extract query string from a URL string

Question

I am reading from history, and I want that when i come across a google query, I can extract the query string. I am not using request or httputility since i am simply parsing

Answer 1

here is the solution -

string GetQueryString(string url, string key)
{
    string query_string = string.Empty;

    var uri = new Uri(url);
    var newQueryString = HttpUtility.ParseQueryString(uri.Query);
    query_string = newQueryString[key].ToString();

    return query_string;
}
