Return multiple values to a method caller

Question

I read the C++ version of this question but didn\'t really understand it.

Can someone please explain clearly if it can be done and how?

Answer 1

A method taking a delegate can provide multiple values to the caller. This borrows from my answer here and uses a little bit from Hadas's accepted answer.

delegate void ValuesDelegate(int upVotes, int comments);
void GetMultipleValues(ValuesDelegate callback)
{
    callback(1, 2);
}

Callers provide a lambda (or a named function) and intellisense helps by copying the variable names from the delegate.

GetMultipleValues((upVotes, comments) =>
{
     Console.WriteLine($"This post has {upVotes} Up Votes and {comments} Comments.");
});
