Following is the simple C# program to swap neighbor characters in a given string,

using System;
using System.Text;
namespace HelloWorld
{
 class Program
 {
   static void Main(string[] args)
   {
     Console.WriteLine(Program.SwapNeighbourChar('DEMO'));  
     Console.ReadLine();      
   }
   public static string SwapNeighbourChar(string strToSwap)  
   {  
       char[] arrStr = strToSwap.ToCharArray();  
       StringBuilder strbuild = new StringBuilder();  
       for (int i = 0; i <= arrStr.Length - 1; i++)  
       {  
           if (i != arrStr.Length - 1)  
           {  
               strbuild.Append(arrStr[i + 1]);  
           }  
           strbuild.Append(arrStr[i]);  
           i = i + 1;  
       }  
       return strbuild.ToString();  
   } 
 }
}

Output: EDOM
