Get values ​​from a string in c#

  • 772

I am trying to get the values ​​of a stringcontaining a url with a QueryString.

This is an example of the URL:

string url = "http://example.com?id=gdjh48vnnnvwsid1dkif84ndn?id2=cjodfnuvbvmf47747";

As you can see, it is a stringand not a QueryStringsince it is not the address of the page where I am, but a url that I get with a HTTPRequest.

I would like to know if there is any way to parse and obtain the values ​​of the url (in this case id1and id2) without using Split, Replace, etc... since this is not a guarantee that it will work 100% of the time (in the value of id1, for example, appears id1).

c#

    You can use the ParseQueryString method of the HttpUtility class.

    Remember that you will need to add a reference to the System.Web assembly if you don't already have it in your project.

            string url = @"http://example.com?id=gdjh48vnnnvwsid1dkif84ndn&id2=cjodfnuvbvmf47747";
        Uri uri = new Uri(url);

        var queryString = HttpUtility.ParseQueryString(uri.Query);

        foreach (var key in queryString.Keys)
        {
            Console.WriteLine($"{key}: {queryString[(string)key]}");
        }
