Question

Below is the perfect working code, when i googled for splitting the first part of the string with a delimiter.

But i have a problem because, this code works only when the target framework is 4
How can i convert this code, where it will run in target framework 2

    Public Shared Function FirstFromSplit(ByVal source As String, ByVal delimiter As String) As String
        Dim i = source.IndexOf(delimiter)

       Return If(i = -1, source, source.Substring(0, i))

    End Function

Answer 1

As far as know both string-methods exists in 2.0, so I guess it’s the return-statement that gives troubles.
Try re-writing it in the old style.

Public Shared Function FirstFromSplit(ByVal source As String, ByVal delimiter As String) As String 
     Dim i = source.IndexOf(delimiter) 

     If i < 0 Then
       return source
     Else
       return source.Substring(0, i)
     End if
End Function
