HttpServerUtility.UrlDecode Method (String, TextWriter)

Decodes an HTML string received in a URL and sends the resulting output to a TextWriter output stream.

Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)

public void UrlDecode(
	string s,
	TextWriter output
)

Parameters

s
Type: System.String

The HTML string to decode.

output
Type: System.IO.TextWriter

The TextWriter output stream that contains the decoded string.

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.

UrlDecode is a convenient way to access the HttpUtility.UrlDecode method at run time from an ASP.NET application. Internally, UrlDecode uses HttpUtility.UrlDecode to decode strings.

The following example decodes the string named EncodedString (received in a URL) into the string named DecodedString.

StringWriter writer = new StringWriter();
Server.UrlDecode(EncodedString, writer);
String DecodedString = writer.ToString();
