You are either returning a value/struct or a reference. Theoretically you cannot return more, but you can instruct the method to assign a value by reference with the `ref` or `out` keyword. — Silvermind, Sep 24 '15 at 12:00

You can use output parameters:

public void Foo(out int bar, out string goo)
{
    bar = 1;
    goo = "moo";
}

And use it like this:

int a;
string b;
Foo(out a, out b);

You can use a Tuple to return more than one value. Keep in mind, they can get out of hand pretty quick.

public Tuple<string, int> Foo()
{
     return Tuple.Create("Bar",1);
}

Tupples can be spun up with multiple values.

Tuple<int,string,int,int,string>

They can get messy quick :)

Good luck

_They can get messy quick_ Yeah, Tuples should be deleted from existence. ;) – Silvermind Sep 24 '15 at 12:28
