"&" inside QueryString value

Question

I'm using QueryStrings for users to auto-select values from a drop down list. Some of the values in this drop down list contain "&" in them.

E.g. "Acquisitions & Development"

When the user passes through a value with an "&", the string value gets cut off before the second half.

string functionalDepartment = Request.QueryString["FunctionalDepartment"];
//returns "Acquisitions "

Is there a way that I can include the second half of the value when getting the value from the QueryString?

Answer 1

The & character needs to be URL encoded because & is used to divide the query string into name=value pairs. When creating the URL, use:

HttpUtility.UrlEncode(url);

Answer 2

Before passing it to query string just replace:

.Replace("&","%26");

or use Server.URLEncode()

Answer 3

You could user System.Web.HttpUtility.UrlEncode while setting the values for the drop down.

This will ensure that & will not break the values.

Answer 4

Use HttpServerUtility.UrlEncode:

URL encoding ensures that all browsers will correctly transmit text in URL strings. Characters such as a ampersand (&) might be truncated or corrupted by some browsers.

Answer 5

Server.UrlEncode("url") will solve ur issue.

Example:

 MyURL = "http://www.ursite.com/urpage.aspx?ReqStr=" + Server.UrlEncode("ASP.NET Examples");
