Question

Why does the Uri class urldecode my url that I send to its contructor and how can I prevent this?

Example (look at the querystring value “options”):

    string url = "http://www.example.com/default.aspx?id=1&name=andreas&options=one%3d1%26two%3d2%26three%3d3";
    Uri uri = new Uri(url); // http://www.example.com/default.aspx?id=1&name=andreas&options=one=1&two=2&three=3

Update:

// ?id=1&name=andreas&options=one%3d1%26two%3d2%26three%3d3
Request.QueryString["options"] = one=1&two=2&three=3

// ?id=1&name=andreas&options=one=1&two=2&three=3
Request.QueryString["options"] = one=1

This is my problem 🙂

Answer 1

why exactly?
you can get to the encoded version using url.AbsoluteUri

EDIT

Console.WriteLine("1) " + uri.AbsoluteUri);
Console.WriteLine("2) " + uri.Query);

OUT:
1) http://www.example.com/default.aspx?id=1&name=andreas&options=one%3d1%26two%3d2%26three%3d3
2) ?id=1&name=andreas&options=one%3d1%26two%3d2%26three%3d3
