VB .NET String Manipulation

I have the following phrases for example:

This is a test for wordA.
This is a test for wordB.

I need to grab the phrase before wordA OR wordB.  So my output for both sentences would be "This is a test for".  I need it to look for both wordA and wordB, grabbing the phrase before either word.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You may use String.SubString, start at position 0, and your max limit will me the IndexOf("wordA") or IndexOf("wordB")
Mike TomlinsonHigh School Computer Science, Computer Applications, and Mathematics TeachersCommented:
You can use the plain old Split() function.  Everything before your word will at Index 0 (zero):
Dim word As String = "wordA"
        Dim str As String = "This is a test for wordA."
        Dim values() As String = str.Split(word)
        Dim phrase As String = values(0)
