String.Contains() - how about a literal string?

[IlyaRabyy]

Colleagues,
Let's say you have a list of prefixes/IDs/whatever that are part of a file name, specifically - 1st two characters.
You go through the files' names in a dir and, depending on that 2-char prefix, rename this file.
Say, prefix may be "AB", "CD", "EF", "GH", but you're interested only in "CD" and "GH".
If it was up to me, I'd do the checking something like this:

Dim cStr As String, cFPref As String
cStr = "CD GH"
cFPref = Mid(cJustFileName, 1, 2)
If cStr.Contains(cFPref) Then
   cFileName ' etc.

However, I have no such luxury like adding my own code into the existing one (takes too long to explain the reasons).
I doubt that

String("CD GH").Contains(cFPref)

would work...
... or it would?
Please advise!
Tnx!

Regards,

Ilya

Hi Ilya,

I'd make use of "StartsWith" instead of Contains:

If cJustFileName.StartsWith("CD") OrElse cJustFileName.StartsWith("GH") Then
End If

This is assuming you got something like this:

cJustFileName = Path.GetFilename(cFile)

or

cJustFileName = Path.GetFilenameWithoutExtension(cFile)
