Can I add an attribute to a function to prevent reentry?

Question

At the moment, I have some functions which look like this:

private bool inFunction1 = false;
public void function1()
{
    if (inFunction1) return;
    inFunctio

You could build a PostSharp attribute to check to see if the name of the method is in the current stack trace

    [MethodImpl(MethodImplOptions.NoInlining)]
    private static bool IsReEntry() {
        StackTrace stack = new StackTrace();
        StackFrame[] frames = stack.GetFrames();

        if (frames.Length < 2)
            return false;

        string currentMethod = frames[1].GetMethod().Name;

        for (int i = 2; i < frames.Length; i++) {
            if (frames[i].GetMethod().Name == currentMethod) {
                return true;
            }
        }

        return false;
    }
