Creating your own methods that have optional parameters

[aewarnick]

I see that some methods have optional parameters. How do I do that?

myClass.myMethod(Optional someParam As String = "")

Id rather overload.

Public Function myMethod () as string
Public Function myMethod (aParm as string) as string
Public Function myMethod (anObj as object) as string

That is probably VB and I dont think you quite know what I mean. I guess the only way is to use method overloading, right?

I see someone already posted that. Ok, got my answer.

It works in VB.NET, being a .NET related forum, I generally try to provide answers that work in .NET.

Ummm... NO. Method overloading is probably a better approach to getting the functionality you require, but the Optional keyword is there just as I said above -- it is exactly what you asked for btw.

Do you have any idea how I would write that optional parameter in C#? I tried a few things but could not get it to compile.

 

[quwiltw]

You cant. You didnt say C# was the language of choice. Optional is a VB.NET keyword so as I said above it works in VB.NET.

C# doesnt support Optional parameters, your only choice is to use function overloading (a better design anyway).

Ok, sounds good to me. Thanks everyone.
