Question

If I have a console application containing the class

public class HelloWorld
{
    public string Hello()
    {
        return "hi";
    }
}

I can go into the immediate window at design time and do

new HelloWorld().Hello()

But, if I try

? Hello()

I get error “The name ‘Hello’ does not exist in the current context”. So it appears I need to instantiate the class first. That makes sense.

But, my confusion comes from the MSDN documentation where they show

Module Module1

    Sub Main()
        MyFunction(5)
    End Sub

    Function MyFunction(ByVal input as Integer) As Integer
        Return input * 2
    End Function

End Module

They say all you have to do is type

?MyFunction(2) in the Immediate window and press Enter.

I’m not a VB.NET guy. Am I correct in assuming I need to instantiate my object first? Why does the VB.NET example differ?

Answer 1

This is in a Module, not in a class. Modules are leftovers from the days of yore (i.e., VB6).
