Func delegate with no return type
All Func delegates return something; all the Action delegates return void.
Func<TResult>
takes no arguments and returns TResult:
public delegate TResult Func<TResult>()
Action<T>
takes one argument and does not return a value:
public delegate void Action<T>(T obj)
Action
is the simplest, 'bare' delegate:
public delegate void Action()
There's also Func<TArg1, TResult>
and Action<TArg1, TArg2>
(and others up to 16 arguments). All of these (except for Action<T>
) are new to .NET 3.5 (defined in System.Core).
... takes no arguments and has a void return type?
I believe Action
is a solution to this.
