remove "\" from the end of string[Resolved]

Code:

---

string path=@"C:\data\test\test2\test3\test4";

---

I have this string and I want to remove all characters starting from the begining till the last backslash "\" char . Note , this is just an example . The string will be changable and has no fixed number of characters .

Result I need is like this :
"test4"

Thanks .

Code:

---

string path=@"C:\data\test\test2\test3\test4";
Regex r = new Regex(@"(.*?\\)+([^\\]*)\\?");
Match m = r.Match(path);
if (m.Success)
        textBox1.Text = m.Groups[2].Value;

Umm , what's this ?how to use ?:D
Don't tell me it's regex coz I've not used them before :rolleyes:

ok posted code

Sorry i just rolled out of bed not quite awake yet.

that expression will return the last directory in the path even if the path ends with a \

Code:

---

string[] path=@"C:\data\test\test2\test3\test4".Split(@"\".ToCharArray());
path[path.Length-1];

---

The above code gives me same result with less overhead and in one line of code . I think I've misexplaind the problem . I need result like this :

\test\test2\test3\test4"
test2\test3\test4"
test3\test4"
test4"---------I've only got this part done .:(

any ideas ?

Thanks Tewl .

This is a Solution using Substrings;
Dont know if its better or worse, just different:

Code:

---

string path =@"C:\data\test\test2\test3\test4";
                        path = path.Substring(path.LastIndexOf(@"\",path.Length,path.Length)+1,path.Length - (path.LastIndexOf(@"\",path.Length,path.Length)+1));

Take Care, Stephan

EDIT-------> Sorry you posted while I was writing! Forget about this. Sorry!

ok i have to think a little more now :o * yawn lol

I'm not completely sure what you are wanting do you want everything after the first path ( test\test2\test3\test4 ) or do you want everything but the drive ( data\test\test2\test3\test4 ) or what :S

is that what you are looking for?

Code:

---

string path =@"C:\data\test\test2\test3\test4";
string output ="";

while(path.LastIndexOf(@"\",path.Length,path.Length)!=-1)
{
        path = path.Substring(path.IndexOf(@"\",0,path.Length)+1,path.Length-(path.IndexOf(@"\",0,path.Length)+1));
        Console.WriteLine(path);
}

Console.ReadLine();

lol , so far we got three different ways but yours is the longest ever .:D

all above code remove all occurances of "\" and return the last word after the last "\" .
ex .
before
string path =@"C:\data\test\test2\test3\test4";

after
test4



While I need to return the following results :
before
string path =@"C:\data\test\test2\test3\test4";

after
data\test\test2\test3\test4
test\test2\test3\test4
test2\test3\test4
test3\test4
test4

System.IO.Path.GetFilename() would work..
