if I'm doing something like that:
someString.Replace("abc","").Replace("def","").Replace(@"c:\Windows","")
How can I replace that with
Regex.Replace(someString," \\here I don't know what the pattern should be")
I've tried this:
Regex.Replace(someString, @"(?:abc|def|c:\Windows)")
but it didn't work
UPD...
The problem is when I pass the path like that
Regex.Replace(someString, @"(?:abc|def|"+aPath+")")
`But it didnt work` doesn't say much helpfull!
Try this:
someString = Regex.Replace(someString, @"(?:abc|def|ghi|c:\\Windows)", "")
It did work when I tried it. I thinks the reason why your code doesn't work is because you forgot the replacement string and you have to escape the backslash in the path.
I'm assuming the thing that "didn't work" is your C:\windows replacement. You need
someString = Regex.Replace(someString, @"(?:abc|def|C:\\windows)","");
The problem is you need to escape your backslash. An unescaped backslash has meaning in regex. In particular, in this case, \W actually matches any non-alphanumeric character.
Edit to escape an any arbitrary string, you can use Regex.Escape(yourString);
\should be\\
