Hi, can someone hlep me to reverse the below logic so that I'm selecting the chars after the final \\. For example in this string C:\inetpub\TESTAPP I want to get the substring TESTAPP as it is after the last instance of the \.

Here's the code I'm using at present which is returning 'inetpub':

C#

string dirpath = @"" + dir;
//Specs wants this to contain the name of the parent directory.
String ss = String.Empty;

int i = dir.LastIndexOf("\\");
ss = dir.Remove(i);
ss = ss.Substring(ss.LastIndexOf("\\") + 1);

string compressedDirpath = @"" + dir + "\\" + ss + ".gz";
string[] argd = { dirpath, compressedDirpath };

Hey there,

Try this to get TESTAPP:

C#

string dirpath = @"" + dir;
//Specs wants this to contain the name of the parent directory.
String ss = String.Empty;
 
ss = dir.Substring(dir.LastIndexOf("\\") + 1);
 
string compressedDirpath = @"" + dir + "\\" + ss + ".gz";
string[] argd = { dirpath, compressedDirpath };

I do not understand why you were doing dir.Remove(i), but it was causing the problem.

Hope it helps.

Azee...
