HttpServerUtility.UrlDecode Method (String)
URL-decodes a string and returns the decoded string.
Assembly: System.Web (in System.Web.dll)
Parameters
- s
-
Type:
System.String
The text string to decode.
URL encoding ensures that all browsers will correctly transmit text in URL strings. Characters such as a question mark (?), ampersand (&), slash mark (/), and spaces might be truncated or corrupted by some browsers. As a result, these characters must be encoded in <a> tags or in query strings where the strings can be re-sent by a browser in a request string.
This method is a convenient way to access the HttpUtility.UrlDecode method at run time from an ASP.NET application. Internally, this method uses HttpUtility.UrlDecode to decode strings.
In the code-behind file for an ASP.NET web page, access an instance of the HttpServerUtility class through the Server property. In a class that is not in a code-behind file, use HttpContext.Current.Server to access an instance of the HttpServerUtility class.
Outside of a web application, use the WebUtility class to encode or decode values.
The following example shows how to URL-decode a value that is retrieved from the query string. The code resides in the code-behind file for a web page. ReturnPage refers to a HyperLink control.
