Question

Is it possible to call a method passing a lambda with variable number of parameters?

For example:

public void Go(Action x)
{
}

I need to call it passing parameters, such as:

Go(() => {});
Go((x, y) => {});
Go((x) => {});

Is it possible? How?

Answer 1

You could create overloads as in

public void Go<T>(Action<T> x)
{
}

Here is an article showing more examples of Action<T>. Notice that it doesn’t return a value, from MSDN:

Encapsulates a method that has a
single parameter and does not return a
value.
