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

```cs
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
```
