The following code example concatenates a person's first, middle, and last name.


using System;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {

      // we want to simply quickly add this person's name together
      string fName = "Simon";
      string mName = "Jake";
      string lName = "Harrows";

      // because we want a name to appear with a space in between each name, 
      // put a space on the front of the middle, and last name, allowing for
      // the fact that a space may already be there
      mName = " " + mName.Trim();
      lName = " " + lName.Trim();

      // this line simply concatenates the two strings
      outputBlock.Text += String.Format("Welcome to this page, '{0}'!", string.Concat(string.Concat(fName, mName), lName)) + "\n";
   }
