reg expression: want stuff after "\" in a string 2

[G00GLER]

string in question happens to be "CM\WilliS"
This Code Works:

					string t = User.Identity.Name;
					string s = Regex.Replace(t, "CM","");
					Message.InnerHtml += s+"<BR>";

But returns "\Willis"
I am having dificulty removing the \

 

[G00GLER]

Regex.Replace(s, @"[^\w\.@-]", "");

removed the special characters, i guess i needed the brackets

 

[G00GLER]

a solution specific to my question:
t = Regex.Replace(s, "\\\\", "");
//yes 4 slashes equals one

Or an alternative without using a regex:

        Dim s As String = "CM\WilliS"
        s = s.Substring(s.IndexOf("\") + 1)

in c sharp why won't this work

TextBox1.Text = strFileName2.Substring(strFileName2.IndexOf("\\\\"),+1);

TextBox1.Text is returning "C:\Documents and Settings\delora\Desktop\12.htm"

when I want it to return 12.htm

shooting from the hip
System.IO.Path.GetFileName

Not quite

string strFileName2 = FILE2.PostedFile.FileName;
FILE2.PostedFile.FileName is the file returned when browsed on clients computer

which returns as an example "C:\Documents and Settings\delora\Desktop\12.htm":

I probably need to use the split()

 

[cappmgr]

string sFileName = System.IO.Path.GetFileName("C:\Documents and Settings\delora\Desktop\12.htm")

sFileName will have 12.htm

You try your post I gave you a star but I can't get it to work I even spelled it out

TextBox1.Text = System.IO.Path.GetFileName("C:\Documents and Settings\delora\Desktop\xi.htm");

it won't compile: Unrecognized escape sequence

 

[G00GLER]

something to do with the slashes

 

[ca8msm]

Try doubling up the slashes e.g. \\

i need to take in a dynamic file path and out put the file name

so are you suggesting i do a search in replace and add \\ where there are only one then use System.IO.Path.GetFileName();

 

[G00GLER]

Thanks you both really appreciate your suggestions,

I ended up getting it to work using the split function and choosing the last in an array.

GOOGlER,
Just saw this looking for something. Glad you solved your problem. For future reference if you get Unrecognized escape sequence
it can usually be fixed by usig ca8msm's \\
TextBox1.Text = System.IO.Path.GetFileName("C:\\Documents and Settings\\delora\\Desktop\\xi.htm");
or
TextBox1.Text = System.IO.Path.GetFileName(@"C:\Documents and Settings\delora\Desktop\xi.htm");

did'nt know which language you where using using.

But surely this is only an artefact of putting the file name in as a literal in the test above. If you already have the file name in a string variable, then you shouldn't need to worry about escaping the backslashes.

TextBox1.Text = System.IO.Path.GetFileName(strFileName2);
