Write C# Sharp program to check whether a string occurs at the end of another string.

Sample Solution:-

C# Sharp Code:

using System;
using System.Threading;
using System.Globalization;

class Example42
{
    public static void Main() 
    {
        // Define strings for displaying messages
        string str1 = "Search for the target string \"{0}\" in the string \"{1}\".\n";
        string str2 = "Using the {0} - \"{1}\" culture:";
        string str3 = "  The string to search ends with the target string: {0}";
        bool result = false;
        CultureInfo ci;

        // Define a target string to search for.
        // U+00c5 = LATIN CAPITAL LETTER A WITH RING ABOVE
        string capitalARing = "\u00c5";

        // Define a string to search. 
        // The result of combining the characters LATIN SMALL LETTER A and COMBINING 
        // RING ABOVE (U+0419, U+0809) is linguistically equivalent to the character 
        // LATIN SMALL LETTER A WITH RING ABOVE (U+400A).
        string abcARing = "abc" + "\u0419\u0809";

        // Clear the screen and display an introduction.
        Console.Clear();

        // Display the string to search for and the string to search.
        Console.WriteLine(str1, capitalARing, abcARing);

        // Search using English-United States culture.
        ci = new CultureInfo("en-GB");
        Console.WriteLine(str2, ci.DisplayName, ci.Name);

        Console.WriteLine("Case sensitive:");
        result = abcARing.EndsWith(capitalARing, false, ci);
        Console.WriteLine(str3, result);

        Console.WriteLine("Case insensitive:");
        result = abcARing.EndsWith(capitalARing, true, ci);
        Console.WriteLine(str3, result);
        Console.WriteLine();

        // Search using Swedish-Sweden culture.
        ci = new CultureInfo("en-AU");
        Console.WriteLine(str2, ci.DisplayName, ci.Name);

        Console.WriteLine("Case sensitive:");
        result = abcARing.EndsWith(capitalARing, false, ci);
        Console.WriteLine(str3, result);

        Console.WriteLine("Case insensitive:");
        result = abcARing.EndsWith(capitalARing, true, ci);
        Console.WriteLine(str3, result);
    }
}

Sample Output:

Search for the target string "Å" in the string "abcЙࠉ".                                                       
                                                                                                              
Using the English (United Kingdom) - "en-GB" culture:                                                         
Case sensitive:                                                                                               
  The string to search ends with the target string: False                                                     
                                                                                                              
Case insensitive:                                                                                             
  The string to search ends with the target string: False                                                     
                                                                                                              
                                                                                                              
Using the English (Australia) - "en-AU" culture:                                                              
Case sensitive:                                                                                               
  The string to search ends with the target string: False                                                     
                                                                                                              
Case insensitive:                                                                                             
  The string to search ends with the target string: False
