In a normal string, you use \\

If this is in a regular expression, it needs to be \\\\

The reason RegEx needs four is because both the String parser and RegEx engine support escapes. Therefore, \\\\ is parsed to \\ by the String parser then to a literal \ by the RegEx parser.

You can write:

String newstr = "\\";

\ is a special character within a string used for escaping.

"\" does now work because it is escaping the second ".

To get a literal \ you need to escape it using \.

string = @"c:\inetpub\wwwroot\"

is the same as

 string = "c:\\inetpub\\wwwroot\\"

in some cases... i'm not 100% sure but i think it might be language dependant... i KNOW "@" works in C#

You escape certain characters by adding "\" in front of the character.

So \\ will work for you.
