In C#
| Code: |
string myStr = "c:\mydir\abc\abc.txt";
string[] arrStr = new string[4];
char[] sep = {'\'};
arrStr = myStr.Split(sep);
for(int x = 0; x < arrStr.Length; x++ )
{
if( x == arrStr.Length - 1 || x == arrStr.Length )
Response.Write(arrStr[x].ToString());
}
|
Will loop through and return the last 2 elements of your array. Not the most elegant solution.

A shorter solution would be:
string Str = "a/b/c/d.txt";
int Index = Str.LastIndexOf('/') + 1;
Console.WriteLine(Str.Substring(Index, Str.Length - Index));

This doesn't return "abc/axd.txt", does it?
Since no one is using the requested language, I'll post mine too! C++ with MOC magic: | Code: | QFileInfo f("C:/program files/aaa/abc/axd.txt");
QString s = f.absoluteDir().dirName() + '/' + f.fileName();
// s is now "abc/axd.txt" |
Or, if you want to handle it as a string: | Code: | QString s("C:/program files/aaa/abc/axd.txt");
s.remove(QRegExp(".*/(?=.*/)"));
// s is now "abc/axd.txt" |
Inverse QString::section() would be cool, but too bad there isn't one.

Couldn't tell you how in VB, I've always hated that language. You could still do it in either C# or C++ using MS Visual C# or MS Visual C++ and still make use of the .NET roll up.
