Anonymous Method Trick

I found out a quick way of using anonymous methods to wrap a call:

WaitCallback callback = delegate(object client)
{
     processString((string)client);
};

ThreadPool.QueueUserWorkItem (callback, "the string");

the target method:

void processString(string initstring)
{
     ...
}

Because the QueueUserWorkItem uses the delegate WaitCallback which accepts an "object" we can use the anon method to do the casting preserving the target method signature.
