First and foremost welcome to Dream.In.Code, hope you enjoy your stay with us.

In the future please post your programming questions in the proper language forum (In this case it's C#, I will move this one for you). Also
Are you receiving any errors? Does this code not work that way you intended it? When asking for help there are a couple items that are vital in order for someone to properly help you:

• Post the code you're having problems with (DONE)
• Post the exact error you're receiving, if you are receiving one
• If no error explain what the code is doing versus what you want it to do
• Post your question in the body of your post, not the description field

Try a temporary array for that. And then something like this:

CODE

int[] myArray = { 2, 4, 6, 8 };
            int[] temparray = new int[myArray.Length];
            for (int i = 0; i < myArray.Length; i++)
            {
                temparray[(myArray.Length-1) - i] = myArray[i]; //the -1 is to convert lenght to index
            }

After that you can use a similar process to copy the temp array back to the original array.

But I guess if you wanted to be lazy you could also use the array.reverse method. Just look it up on msdn, it can help you a lot in the future to use this as a reference. To help you out now, the usage is Array.Reverse(myArray);
