c# - event.Invoke(args) vs event(args). Which is faster?

Question

Which is faster; using event.Invoke(args), or just calling event(args). What's the difference? Is one faster or slower than the other; or is it just a matter of preference?

Answer 1

Writing someDelegate(...) is a compiler shorthand for someDelegate.Invoke(...).
They both compile to the same IL—a callvirt instruction to that delegate type's Invoke method.

The Invoke method is generated by the compiler for each concrete delegate type.

By contrast, the DynamicInvoke method, defined on the base Delegate type, uses reflection to call the delegate and is slow.
