Hi all,

Not sure if anyone can help me..

I have written a Proper Case function which does, well exactly what it says on the tin...what I would like to do now is add it to the String class, appreciating that I can't I was hoping that I could write my own class - lets say RobsStringClass which would inherit the system.string class and then also have my nice new function.

Alas this doesn't seem to be the case as the string class appears to be sealed..

I was hoping that a user of my class would be able to do something like this:

Dim myString As String

myString = "HELLO WORLD"

myString = myString.ToProperCase()

the end result being:

Hello World

Can anyone suggest a way to get all of the functionality from String into another class where I can add my own function too?

Thanks in advance for any help.

Regards

Rob

You can create your own class for this, but you can't like inherit from the string class, that I know of. You can create your own custom helper class.

Hi Brian,

Thanks for your reply.

Yeah, the not being able to inherit from the String class is a bit of a pain, someone on a news group suggested that the String class was one of the most used, I guess it's probably one of the weighty ones also so perhaps I dont want a class with that included in it, I don't know...

I already have a class for the ProperCase method, but I cant achieve my goal of :

myString = myString.ToProperCase

using it...instead I have to:

myString = ProperCase(myString)

just doesn't look as nice (cosmetically) albeit the result is the same...

You could use myString = myString.ProperCase(), if you declare ProperCase shared/static.

Hi Brian,

Thanks for your reply.

Would it be possible for you to give me an example of how to do that? I'm relatively new to .net (had training a year ago but have only been using it for a few months, so slow process etc).

Thanks in advance for any help.

Rob

Actually, my previous post was wrong (sorry), if you assign the string to the class and not make it static, it may work without the parameter, just have a value private field that stores the underlying string value. If you wanted to do it as a shared function, you need to pass the string, and define it as such:

Public Shared Function ProperCase(text as string) as string
  'Transform
end function

Sorry for the mixup.
