Hi, I'm using visual studio.net 2003 and I wanna create a function like the Split function in vb.net

Split("DFSFDS","|",-1,CompareMethod.Binary

see image

So what I want to do is a dropdown list of my options of my custom function like this

Public Function Color("Red") As String
'Code when option is red, Blue or any other color
End Function


So I want instead of "Red", a dropdown of my colors to be displayed when I call this function from my class.
