Func<T>() vs Func<T>.Invoke()
C#InvokeFuncC# Problem Overview
I'm curious about the differences between calling a Func<T>
directly vs. using Invoke()
on it. Is there a difference? Is the first syntactical sugar and calls Invoke()
underneath anyway?
public T DoWork<T>(Func<T> method)
{
return (T)method.Invoke();
}
vs.
public T DoWork<T>(Func<T> method)
{
return (T)method();
}
Or am I on the wrong track entirely?
C# Solutions
Solution 1 - C#
There's no difference at all. The second is just a shorthand for Invoke
, provided by the compiler. They compile to the same IL.
Solution 2 - C#
Invoke works well with new C# 6 null propagation operator, now you can do
T result = method?.Invoke();
instead of
T result = method != null ? method() : null;
