Why being so lazy? I searched with your subject in Google[^] and I found About 1,160,000 results (0.20 seconds).

[Edit]Added definition[/Edit]

This error occurs when you are performing a foreach loop over a generic list or a collection and there is a line of code inside the loop that is trying to modify the contents of the list.

Question is not complete ..
I think you are trying to change the values in the collection while looping/iterating the same collection by iterating statements...
