C# Return Different Types?

Question

I got something like this:

public [What Here?] GetAnything()
{
     Hello hello = new Hello();
     Computer computer = new Computer();
     Radio radio = ne

Defining a single type for all is not always possible. Even if when you can, the implementation is rarely easy. I prefer to use out parameters. The only caveat is that you need to know all the return types in advanced:

public void GetAnything(out Hello h, out Computer c, out Radio r)
{
     /// I suggest to:
     h = null;
     c = null;
     r = null; 
     // first, 

     // Then do whatever you have to do:
     Hello hello = new Hello();
     Computer computer = new Computer();
     Radio radio = new Radio();
}

The return type can be a void, or something else, like bool an int or a predefined enum which can help you check for exceptions or different cases wherever the method is used.
