Windows XP中的应用程序异常

Question

I have a C# app which works on Windows 7, but does not work on Windows XP. The program crashes when I try to close a program window. The window doesn't have any extra functions when closing, and the parent window is not waiting for any results.

Here is the exception:

System.InvalidOperationException: Collection was modified; enumeration operation may not execute.

Answer 1

I've added try block in dispose and a'm not having that issue any more, but I guess problem still is here.

Block:

    protected override void Dispose(bool disposing)`
    {
        try
        {
            if (disposing)
            {
                if (components != null)
                {
                    components.Dispose();
                }
            }
            base.Dispose(disposing);
        }
        catch
        {

        }
    }
