I am trying find a string in below string.
http://example.com/TIGS/SIM/Lists/Team Discussion/DispForm.aspx?ID=1779
by using http://example.com/TIGS/SIM/Lists
string. How can I get Team Discussion
word from it?
Some times strings will be
http://example.com/TIGS/SIM/Lists/Team Discussion/DispForm.aspx?ID=1779
I need `Team Discussion`
http://example.com/TIGS/ALIF/Lists/Artifical Lift Discussion Forum 2/DispForm.aspx?ID=8
I need `Artifical Lift Discussion Forum 2`

Here is another solution that provides the following advantages:
This method, however, DOES rely on the following assumptions, which I consider to be the least likely to change:
Basically, I just split the string twice, using text that I expect to be surrounding the area I am interested in.
String urlToSearch = "http://example.com/TIGS/SIM/Lists/Team Discussion/DispForm.aspx";
String result = "";
// First, get everthing after "/Lists/"
string[] temp1 = urlToSearch.Split(new String[] { "/Lists/" }, StringSplitOptions.RemoveEmptyEntries);
if (temp1.Length > 1)
{
// Next, get everything before the first "/"
string[] temp2 = temp1[1].Split(new String[] { "/" }, StringSplitOptions.RemoveEmptyEntries);
result = temp2[0];
}
Your answer will then be stored in the 'result' variable.

This solution will get you the last directory of your URL regardless of how many directories are in your URL.
string[] arr = s.Split('/');
string lastPart = arr[arr.Length - 2];
You could combine this solution into one line, however it would require splitting the string twice, once for the values, the second for the length.

If you wanted to see a regular expression example:
string input = "http://example.com/TIGS/SIM/Lists/Team Discussion/DispForm.aspx?ID=1779";
string given = "http://example.com/TIGS/SIM/Lists";
System.Text.RegularExpressions.Regex regex = new System.Text.RegularExpressions.Regex(given + @"\/(.+)\/");
System.Text.RegularExpressions.Match match = regex.Match(input);
Console.WriteLine(match.Groups[1]); // Team Discussion

If you're always following that pattern, I recommend @Justin's answer. However, if you want a more robust method, you can always couple the System.Uri
and Path.GetDirectoryName
methods, then perform a String.Split
. Like this example:
String url = @"http://example.com/TIGS/SIM/Lists/Team Discussion/DispForm.aspx?ID=1779";
System.Uri uri = new System.Uri(url);
String dir = Path.GetDirectoryName(uri.AbsolutePath);
String[] parts = dir.Split(new[]{ Path.DirectorySeparatorChar });
Console.WriteLine(parts[parts.Length - 1]);
The only major problem, however, is you're going to wind up with a path that's been "encoded" (i.e. your space is now going to be represented by a %20
)

Here's a simple approach, assuming that your URL always has the same number of slashes before the are you want:
var value = url.Split(new[]{'/'}, StringSplitOptions.RemoveEmptyEntries)[5];
