C# Empty Statement

Question

The C# language specification defines the empty-statement grammar production, which allows me to do something like this:

static void Main(string[] a         


        

Answer 1

Here are two uses:

while(DoSomething()) ;

and

void M() {
    if(someCondition) goto exit;
    // ...
    exit: ;
}

There are many others. It's a useful device anytime there is nothing to do but a statement is required.
