VS 2008 : Process.StartInfo.Arguments With A Collection Of Files?

I need to pass a file's name as an argument and a switch to the executable I'm using.I'm doing it like this:

vb.net
proc.StartInfo.Arguments = "-z ""C: est.txt"""

I'll know where the files are that I need to grab, but I won't always know the exact names. So, I thought I could grab a collection of the files, store them in a variable, and then pass them as an argument.I tested it with one file like this:

vb.net
Dim File As New System.IO.FileInfo("C:...Desktop est.txt") Dim proc As New Process proc.StartInfo.WorkingDirectory = "..." proc.StartInfo.FileName = "....exe" proc.StartInfo.Arguments = "-z" & File & "additional arugments" proc.Start() proc.WaitForExit()

But, as you all may already know, I can't use the & operator with a string and FileInfo.Would I have to then convert the FileInfo to a string first and then pass it through?
