By utilizing closures with anonymous methods, you can simplify this more.

For example:

string input1 = “Input data 1″;
string input2 = “Input data 2″;
ThreadPool.QueueUserWorkItem(delegate
{
// Safe to use enclosing variables here using closures
Debug.WriteLine(input1);
Debug.WriteLine(input2);
}

What is the reference “s” in the following?
s => callback((T)s)

I’m assuming it’s a reference to an anonymous object, but I’m not sure.

This makes me clearer. Thanks a lot.

Thanku very much. Post very useful. Was able to solve my problem of not being able to send multiple parameters using threads.

Hey everyone,
Sorry about the formatting mixup. Some anonymous type annotations () had been eaten by the blog engine. Hopefully this update fixes everything, though it’s not as clean as I’d like (trying VS2010 Beta + Live Writer on Win7 RC). Let me know if I missed something.

By the way, as I’ve been using this in my own code, I just found it easier to use the built-in Action delegate instead of defining my own WaitCallback delegate that takes one argument of type T and returns void.

Ah, I’d totally missed that typo. Yes, HTML protection in effect. Thanks for the heads up! Fixed
