Being new to regular expressions, I find myself confused by an error

message that I'm getting whilst attempting to perform a simple

regex.replace.



I need to take a simple string such as "c:\intranet\aspnet" and delete

the "c:\intranet\" from the beginning (just leaving aspnet at the end)



The following is the code I'm attempting to use.



..........



Dim regexp as Regex =3D new Regex("c:\intranet\", 

RegexOptions.IgnoreCase)



strViewLocation =3D regexp.Replace(strBaseDir, "")



..........



The error I'm getting is...



System.ArgumentException: parsing "c:\intranet\" - Unrecognized escape

sequence \i. Parameter name: c:\intranet\



I think asp.net is interpreting the \ in the middle of the string as

being an expression of some sort, how do I get asp.net to ignore that

and just read it as a string?!



Thanks in advance for any help with this.

$subst('Email.Unsub'). 

One or two suggestions...

Use the replace function and put two \\ for each \ and make the c:\intranet\ a

string var and put the var in the program.

Thanks



The double \\ for every \ made it work!

You can also use the verbatim sign as in

@"D:\\myDirectory\myfile.fil"  which forces compiler to read the string and

all characters literally.
