Grab a part of text when it matches, get rid of the rest because it's useless

I have a text called

string path = "Default/abc/cde/css/";

I want to compare a text.

string compare = "abc";

I want a result

string result = "Default/abc";

The rest of the path /cde/css is useless.Is it possible to grab the desire result in asp.net c#. Thanks.

I suggest that if you meet questions of this kind in the future, you should try it yourself first.

string result = path.Contains(compare) ? path.Substring(0, (path.IndexOf(compare) + compare.Length)) : path;

Try this. This will loop through the different levels (assuming these are directory levels) until it matches the compare, and then exit the loop. This means that if there is a folder called abcd, this won't end the loop.

string path = "Default/abc/cde/css";
string compare = "abc";
string result = string.Empty;
foreach (string lvl in path.Split("/")) {
    result += lvl + "/";
    if (lvl == compare)
    {
        break;
    }
}
if (result.Length>0)
{
   result = result.substring(0, result.length-1);
}

Is this what you looking for?:

string result = path.Substring(0, path.IndexOf(compare)+compare.Length);

string path = "Default/abc/cde/css/";
string answer = "";
string compare = "abc";

if (path.Contains(compare ))
{
     answer = path.Substring(0, path.IndexOf(stringToMatch) + compare.Length);
}

Something like the above should work.
