I have a fairly simple RegEx code below.

I am given a file name, (which I don't control) , and need to change a
folder name in it.

The code below is choking on the filename not being escaped.

"Unrecognized escape sequence"

While I can escape the findValue and replaceValue,
I don't necessarily control the fileName value. Aka, all I can do is
manually string.Replace the fileName value. (Unless someone knows better
than I)

Do I have to do a string.Replace here? ( to make all the \ into \\ )

Or am I missing some trick in vb.net.

----------Start VB.Net code

Dim fileName As String

fileName = "C:\wutemp\myfile.txt" '<< this is given to me, I cannot simply
say " filename = "C:\\wutemp\\myfile.txt" "

Dim replaceRegEx As System.Text.RegularExpressions.Regex = New
System.Text.RegularExpressions.Regex(fileName, getRegexOptions())

Dim findValue As String = "\wutemp\"

Dim replaceValue As String = "\newfolder\"

Dim newFileName As String = replaceRegEx.Replace(fileName, findValue,
replaceValue)

Private Function GetRegexOptions() As RegexOptions

Dim options As RegexOptions = New RegexOptions

options = options Or RegexOptions.IgnoreCase

Return options

End Function

PS
This is a repost. But I marked the other post (in .language.vb) as "IGNORE
do not reply here".

Why not just use the Path class in the System.IO namespace?

string filename = @"c:\wutemp\myfile.txt";
string replaceValue = @"c:\newfolder";
string newFileName = Path.Combine(replaceValue,
Path.GetFileName(filename));
