The opposite of the StartsWith() method is the EndsWith() method of String class, which determines if the value in a String object ends with a specified String or not.

Some overloads of EndsWith() method

Methods	Description
EndsWith(String)	This method determines whether the ending of the invoked String matches with String object passed to this method.
EndssWith(String, StringComparison)	This method determines whether the ending of the invoked String matches with String object passed to this method, when compared using specified StringComparison.
EndsWith(String, Boolean, CultureInfo)	This method determines whether the ending of the invoked String matches with String object passed to this method, when compared using specified CultureInfo.

Example of EndsWith(String)

Let us explain the first overload version of EndsWith() method. In the upcoming code, we have a String object initialized to a value A Blue Moon and we are going to check whether it ends with a specific String value by calling the EndsWith() method.

//C# EndsWith() method of String.


using System;

class StringEndsWith
{
public static void Main()
{
	String str1 = "A Blue Moon";
	Console.WriteLine("String is: "  + str1);

	bool boo1 = str1.EndsWith("Moon");
	Console.WriteLine("Does "+ str1 + " ends with Moon ? "+ boo1);  

	boo1 = str1.EndsWith("on");
	Console.WriteLine("Does "+ str1 + " ends with on ? "+ boo1); 

	boo1 = str1.EndsWith("Moons");
	Console.WriteLine("Does "+ str1 + " ends with Moons ? "+ boo1); 

	boo1 = str1.EndsWith("A Blue");
	Console.WriteLine("Does "+ str1 + " ends with A Blue ? "+ boo1);  
}
}

Output is :

String is: A Blue Moon
Does A Blue Moon ends with Moon ? True
Does A Blue Moon ends with on ? True
Does A Blue Moon ends with Moons ? False
Does A Blue Moon ends with A Blue ? False

Program Analysis

• In the first comparison, EndsWith() method returns True, as the String object A Blue Moon ends with Moon.
• The next EndsWith() method returns True, as String object A Blue Moon ends with on.
• The next EndsWith() method returns False, as String object A Blue Moon does not end with Moons.
• The final EndsWith() method returns False, as String object A Blue Moon doesn't end with a String A Blue, it rather starts with it.

The EndsWith(String) performs a case-sensitive comparison.

By default, the first overload version of EndsWith() checks for comparison between String value passed to it and the invoked String object by conforming to the case sensitivity of each letter.

//C# EndsWith() method of String.

using System;

class StringEndsWithEx
{
public static void Main()
{
	String str1 = "A Mango Tree";
	Console.WriteLine("String is: "  + str1);

	bool boo1 = str1.EndsWith("Tree");
	Console.WriteLine("Does "+ str1 + " ends with Tree ? "+ boo1);  

	boo1 = str1.EndsWith("tree");
	Console.WriteLine("Does "+ str1 + " ends with tree ? "+ boo1);

	boo1 = str1.EndsWith("mango Tree");
	Console.WriteLine("Does "+ str1 + " ends with mango Tree ? "+ boo1);  
}
}

Output is :

String is: A Mango Tree
Does A Mango Tree ends with Tree ? True
Does A Mango Tree ends with tree ? False
Does A Mango Tree ends with mango Tree ? False

Program Analysis

In the upcoming code, we have a String object initialized to a value A Mango Tree
• In the first comparison, EndsWith() method returns True, as the String object ends with Tree.
• The next EndsWith() method returns False, as String object does not end with tree(with a lower case t).
• The last EndsWith() method returns False, as String object doesn't end with mango Tree(with a lower case m in mango).

Example of EndsWith(String, StringComparison)


In the upcoming code, we are going to explain the second overload of EndsWith() method i.e. EndsWith(String, StringComparison), which determines whether the ending of the invoked String matches with String object passed to this method, when compared using a specified value of the StringComparison Enum.

The StringComparison is an Enum which specifies culture, sort, case rules to be used by whem the comparison is made between String objects. Its all important 6 fields are explained below.




Fields of StringComparison	Value	Description
CurrentCulture	0	Compares String objects using culture-sensitive sort rules and current culture.
CurrentCultureIgnoreCase	1	Compares String objects using culture-sensitive sort rules and current culture, while ignoring the case of the String objects being compared.
InvariantCulture	2	Compares String objects using culture-sensitive sort rules and invariant culture.
InvariantCultureIgnoreCase	3	Compares String objects using culture-sensitive sort rules and invariant culture, while ignoring the case of the String objects being compared.
Ordinal	4	Compares String objects using ordinal(binary) sort rules.
OrdinalIgnoreCase	5	Compares String objects using ordinal(binary) sort rules, while ignoring the case of the String objects being compared.



Note: The EndsWith(String, StringComparison) method also performs a case-sensitive search, unless you pass a specific field of StringComparison with IgnoreCase specified in it.



//C# Example of EndsWith(String, StringComparison) method of String.

using System;

class StringEndsWith
{
public static void Main()
{
	String str1 = "A kind heart";
	Console.WriteLine("String is: "  + str1);


	//String comparison made using StringComparison.CurrentCulture
	Console.WriteLine("String comparison by StringComparison.CurrentCulture:");
	
	bool boo1 = str1.EndsWith("heart", StringComparison.CurrentCulture);
	Console.WriteLine("Does "+ str1 + " ends with heart ? "+ boo1); 

	boo1 = str1.EndsWith("arts", StringComparison.CurrentCulture);
	Console.WriteLine("Does "+ str1 + " ends with arts ? "+ boo1);  



	//String comparison made using StringComparison.CurrentCultureIgnoreCase
	Console.WriteLine("String comparison by StringComparison.CurrentCultureIgnoreCase:");

	boo1 = str1.EndsWith("ART", StringComparison.CurrentCultureIgnoreCase);
	Console.WriteLine("Does "+ str1 + " ends with ART ? "+ boo1);

	boo1 = str1.EndsWith("hearts", StringComparison.CurrentCultureIgnoreCase);
	Console.WriteLine("Does "+ str1 + " ends with hearts ? "+ boo1);

	

	//String comparison made using StringComparison.InvariantCulture
	Console.WriteLine("String comparison by StringComparison.InvariantCulture: ");

	boo1 = str1.EndsWith("heart", StringComparison.InvariantCulture);
	Console.WriteLine("Does "+ str1 + " ends with heart ? "+ boo1);  

	boo1 = str1.EndsWith("arts", StringComparison.InvariantCulture);
	Console.WriteLine("Does "+ str1 + " ends with arts ? "+ boo1); 



	//String comparison made using StringComparison.InvariantCultureIgnoreCase
	Console.WriteLine("String comparison by StringComparison.InvariantCultureIgnoreCase: ");

	boo1 = str1.EndsWith("ART", StringComparison.InvariantCultureIgnoreCase);
	Console.WriteLine("Does "+ str1 + " ends with ART ? "+ boo1);

	boo1 = str1.EndsWith("hearts", StringComparison.CurrentCultureIgnoreCase);
	Console.WriteLine("Does "+ str1 + " ends with hearts ? "+ boo1);



	//String comparison made using StringComparison.Ordinal
	Console.WriteLine("String comparison by StringComparison.Ordinal: ");

	boo1 = str1.EndsWith("heart", StringComparison.Ordinal);
	Console.WriteLine("Does "+ str1 + " ends with heart ? "+ boo1);  

	boo1 = str1.EndsWith("arts", StringComparison.Ordinal);
	Console.WriteLine("Does "+ str1 + " ends with arts ? "+ boo1); 


	
	//String comparison made using StringComparison.OrdinalIgnoreCase
	Console.WriteLine("String comparison by StringComparison.OrdinalIgnoreCase: ");

	boo1 = str1.EndsWith("ART", StringComparison.OrdinalIgnoreCase);
	Console.WriteLine("Does "+ str1 + " ends with ART ? "+ boo1);

	boo1 = str1.EndsWith("hearts", StringComparison.CurrentCultureIgnoreCase);
	Console.WriteLine("Does "+ str1 + " ends with hearts ? "+ boo1);
}
}





Output is :




String is: A kind heart
String comparison by StringComparison.CurrentCulture:
Does A kind heart ends with heart ? True
Does A kind heart ends with arts ? False
String comparison by StringComparison.CurrentCultureIgnoreCase:
Does A kind heart ends with ART ? True
Does A kind heart ends with hearts ? False
String comparison by StringComparison.InvariantCulture:
Does A kind heart ends with heart ? True
Does A kind heart ends with arts ? False
String comparison by StringComparison.InvariantCultureIgnoreCase:
Does A kind heart ends with ART ? True
Does A kind heart ends with hearts ? False
String comparison by StringComparison.Ordinal:
Does A kind heart ends with heart ? True
Does A kind heart ends with arts ? False
String comparison by StringComparison.OrdinalIgnoreCase:
Does A kind heart ends with ART ? True
Does A kind heart ends with hearts ? False











Example of EndsWith(String, Boolean, CultureInfo)


This version of EndsWith() method determines whether the beginning of the invoked String matches with String object passed to this method, when compared using specified CultureInfo.

To do this, we will call the constructor of the CultureInfo class that accepts a String(representing the culture) and a bool value that specifies whether to use the user-selected culture settings from the system or not.



//C# Example of EndsWith(String, Boolean, CultureInfo)


using System;
using System.Globalization;

class StringUpper
{
public static void Main()
{
	//Extracting and printing the current culture of our system
	CultureInfo current = CultureInfo.CurrentUICulture;
	Console.WriteLine("The current UI culture of our system is {0}", current.Name);

	
	//Creating a String object and printing it
	String str1 = "Share Smiles";
	Console.WriteLine("String is: "  + str1);  


	//Creating an object of CultureInfo class based on the English-US culture 
	CultureInfo ci1 = new CultureInfo("en-us", false);

	//Creating an object of CultureInfo class based on the Turkish-Turkey culture 
	CultureInfo ci2 = new CultureInfo("tk-TR", false);
	
	//Creating an object of CultureInfo class based on the Turkish-Turkey culture 
	CultureInfo ci3 = new CultureInfo("fr-FR", false);


	//Comparing String objects according to English-United States culture 
	Console.WriteLine("Based on English-US culture, does " + str1 + " ends with Share ? " + str1.EndsWith("Smiles", false, ci1));

	//Comparing String objects according to Turkish-Turkey culture 
	Console.WriteLine("based on Turkish-Turkish culture, does " + str1 + " ends with Share ? " + str1.EndsWith("Smiles", false, ci2));

	//Comparing String objects according to French-France culture 
	Console.WriteLine("Based on French-France culture, does " + str1 + " ends with Share ?" + str1.EndsWith("Smiles", false, ci3));
}
}





Output is :




The current UI culture of our system is en-US
String is: Share Smiles
Based on English-US culture, does Share Smiles ends with Share ? True
based on Turkish-Turkish culture, does Share Smiles ends with Share ? True
Based on French-France culture, does Share Smiles ends with Share ?True


In our last example, we have made a Comparison between String object according to different cultures, by using an instance of CultureInfo class passed to a variant of the EndsWith() method.
