返回两个字符之间的值？

Question

If we use the example string:

localhost:12345/MATCH_THIS_PART/more_strings

How would I return the value MATCH_THIS_PART and set it as the value of returnString . I think the problem can be solved using regex, and this is what I think would work:

string returnString = Regex.Match(Request.UrlReferrer.ToString(), @"not sure what goes here");

So basically, what goes in the part where I put

"not sure what goes here"

Answer 1

There are several options. String splitting is the easiest one:

string part = Request.UrlReferrer.ToString().Split('/')[1]; // gets the second item

Or use this regular expression and get the first capture:

.*?\/(.*?)\/.*
