In the other hand why are you not using you own derivated type
Just create a class named "String1" or other
With inherit String[]
Use it every where you need
Dim myarray as new string1
Just somme return that need to be passed to a string1 type
For example split()
You can't do split(...). myarrayfunction
You must do
Dim myarray as string1 = split(...)
Myarray.myarrayfuntion
But you lost only 1 line.
