This is my code. I am learning this through the microsoft C# for absolute beginners book. I am on chapter 8 on the final soccer program and have no errors. The only problem I have is when I run it. I get $exception {Index was outside the bounds of the Array} on line of code that is stared. I have been trying to figure this out for the past few hours and have no idea on how to fix it.

On what line is the exception thrown? The error states you are using an index greater than what is possible.

line 109 (still quite new to all of this code)

It looks like your array is 5 in size. So you can put 0 to 4 in the reference and 5 is too much. Fix or cheat? Create a six element array?
I can't guess where you are in learning to code but my view is to understand arrays better. If it's a one off piece of code you are not submitting to review, just make it work.

After line 126, add the following (for troubleshooting purposes):

string msg = string.Empty;
msg += "x: " + x.ToString() + System.Environment.NewLine;
msg += "y: " + y.ToString() + System.Environment.NewLine;
msg += "SHOT: " + SHOT.ToString() + System.Environment.NewLine;
msg += "GOALIE: " + GOALIE.ToString() + System.Environment.NewLine;
msg += "picPlay Length is " + picPlay.Length  + " -- Index numbers are 0 to " + (picPlay.Length - 1) + System.Environment.NewLine;

MessageBox.Show(msg, "Values");

What is the value of "SHOT"? Where is this value set?

Also, line 67 you have for (int i = 0; i < 6; i++) which should be i < 5.

How do you have "myPics" defined?

Fixed it thanks for your input. I retyped it out into a new project and it worked.
