This is the simple C# program to reverse the order of words in a given string,

using System;
using System.Text;
namespace HelloWorld
{
  class Program
  {
    static void Main(string[] args)
    {
    Program.ReverseWordOrder("Hello World");   
    }
    static void ReverseWordOrder(string str) 
    { 
        int i; 
        StringBuilder reverseWord = new StringBuilder(); 

        int Start = str.Length - 1; 
        int End = str.Length - 1; 

        while (Start > 0) 
        { 
            if (str[Start] == ' ') 
            { 
                i = Start + 1; 
                while (i <= End) 
                { 
                    reverseWord.Append(str[i]); 
                    i++; 
                } 
                reverseWord.Append(' '); 
                End = Start - 1; 
            } 
            Start--; 
        } 

        for (i = 0; i <= End; i++) 
        { 
            reverseWord.Append(str[i]); 
        } 
       Console.WriteLine(reverseWord.ToString()); 
    }
  }
}
Output:  World Hello
