using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // Declaring and initializing address1
        char ch = 'c';
  
        // Converting the specified character 
        // into its hexadecimal equivalent
        // using HexEscape() method
        string value = Uri.HexEscape(ch);
  
        // Displaying the result
        Console.WriteLine("Hexadecimal Equivalent is: {0}", value);
    }
}

输出：
