An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll

I wrote a code in asp.net that read data from files and draw a graph.

It worked but after awhile when i run the program, this exception arise

"An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll"

in this statement in the code:

if (File.Exists(fName)) <----(here is the exception)
{
    stream = File.Open(fName, FileMode.Open);
    g_day = Deserialize(stream);
    stream.Close();
    int cn = 0;
    if (g_day.Values.Count != 0)
        cn = g_day.Values[g_day.Values.Count - 1].Value;
    Label1.Text = cn.ToString();
}

Your function is probably calling itself recursively an infinite number of times.

Sometimes this happens indirectly: you call a method in the BCL and it calls back to your code, and this keeps repeating. File.Exists is probably not the culprit. Look at your call stack when the error occurs.
