Question

I have the string string test="http://www.test.com//web?testid=12".

I need to replace with in the string // into /.

Problem is if I use string a=test.replace("//","/") I get http:/www.test.com/web?testid=12 all with single slash(/) but I need http://www.test.com/web?testid=12.

I need only the second // nearby web, not first // near by www.

How to do this?

Answer 1

string test = @"http://www.test.com//web?testid=12";
test = test.Substring(0, test.LastIndexOf(@"//") - 1) 
       + test.Substring(test.LastIndexOf(@"//")).Replace(@"//", @"/");

Or since its a Uri, you can do:

Uri uri = new Uri(test);
string newTest = uri.Scheme + @"//" + uri.Authority 
                                    + uri.PathAndQuery.Replace(@"//",@"/");
