Is 'void' a valid return value for a function?

Question

private void SaveMoney(string id...)
{
    ...
}

public void DoSthWithMoney(string action,string id...)
{
    if(action=="save") return SaveMoney(string id);
    ...
}

Why won't C# let me return the void of the private function back through the public function? It even is the same data type "void"...

Or isn't void a data type?

Is the following code really the shortest workaround?

if(action=="save") {
    SaveMoney(string id);
    return;
}

Answer 1

void is not a type in C#. In this instance, void means the absence of a return type or value so you cannot use it with return as you have in the first example.

This is different to C, for example, where void can mean typeless or an unknown type.
