.NET regex

[gorgor]

I always think I understand regex's until I go to use them. I'm using C# and .NET Framework. Let's say I have the following string:

"C:\\MsDev\\Sharp\\bin\\Debug\\Control.dll`~`3`~`0`~`" notice that `~` is my delimiter

I want to extract the filename from the string using regex.

I think the following snippet should work, but it is assigning 'filename' with the entire string, not just the filename. Any ideas?? Thanks in advance.

//Get the filename from string using regex...
string filename = (Regex.Replace(dataString, "^(.*)(`~`)?", "$1")).ToString();

The whole string matches always with (.*).
Yopu should change the pattern or use the following statements to extract the file name:

string sPath = "C:\\MsDev\\Sharp\\bin\\Debug\\Control.dll`~`3`~`0`~`" ;  
string sFileName = (sPath.IndexOf("`~`") == -1 )? sPath : sPath.Substring(0,sPath.IndexOf("`~`"));

Any reason why you can't use the Split method on the String object?

string delimStr = "~";
char [] delimiter = delimStr.ToCharArray();
string [] split = sPath.Split(delimiter);
sFileName = split[0];

I'll be using the split later. Before I do the split, I need to extract the filename (and a couple other things)from the string. Obislavu's suggestion works perfectly. Thanks!
