using System;

using System.Collections.Generic;

using System.Text;

namespace ConsoleApplication1

{

class Program

{

static void Main(string[] args)

{

for(int cnt=1;cnt<6;cnt++)

{

Console.WriteLine("Loop Iteration");

switch(cnt)

{

case 1: Console.WriteLine("one"); break;

One or more of your "case" statements does not have a break command:

switch (variableName) {
case value1:
// .. some code goes here.
case value2:
// .. some more code here.
}

Whereas this would work:

switch (variableName) {
case value1:
// .. some code goes here.
break;
case value2:
// .. some more code here.
break;
}

Hi, Umesh_karthy_41cdd8

Yes, you've lost break keywords. Put it in your mind that case is just used as a sign, like a sign for goto statement.

If you don't put break after case the switch logic can't be accomplished well, so the compile error occurred.

You may first learn how to use switch keywords: http://msdn2.microsoft.com/en-us/library/06tc147t(VS.80).aspx
