Overloading function call operator in C#

Question

Is it possible to overload the default function operator (the () operator) in C#? If so - how? If not, is there a workaround to create a similar affect?

Thanks,

You mention that you want to do logging, here is how you could do that with delegates:

FooBar MyAlgorithm(Foo paramA, Bar paramB, Actions logger) {
    logger("Starting algorithm.")
    FooBar result = ...;
    logger("Finished algorithm.");
    return result;
}

When you run this you could log to the console:

MyAlgorithm(a, b, (text) => Console.WriteLine(text));

Or log to a Windows Forms TextBox:

TextBox logbox = form.GetLogTextBox();
MyAlgorithm(a, b, (text) => logbox.Text += text + Environment.NewLine);
