Url Encoding with Multiple Query String Parameters

Question

In my c# code I am encoding my Url that has multiple query strings. When at the receiver end I try to read back the query strings I get the null values (query string parameter is not found) reason being encoding changes &querystringparameter to &querystringparam. How to get around this.

Response.Redirect(HttpUtility.HtmlEncode("Add.aspx?ID=" + 1 + "&cid="+ 8 + "&jid=" +9));

On the add.aspx page i get the url as "add.aspx?id=1&sid=3&jid=9"

Solution 1

Use HttpUtility.UrlEncode, I bet it will work like a charm. Read this article for more information.

Solution 2

The biggest issue is that you're encoding the whole query string. You need to encode the individual components, then concatenate them together.

you mean where I read the query string or instead of HttpUtility.HtmlEncode?
