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
)
public void UrlDecode (
	String s, 
	TextWriter output
)
public function UrlDecode (
	s : String, 
	output : TextWriter
)

Parameters

s

The HTML string to decode.

output

The TextWriter output stream containing the decoded string.

URL encoding ensures that all browsers will correctly transmit text in URL strings. Characters such as ?, &, /, and spaces might be truncated or corrupted by some browsers, so those 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 System.Web.HttpUtility.UrlDecode method at run time from an ASP.NET Web application. Internally, UrlDecode uses System.Web.HttpUtility.UrlDecode to decode strings.

The following code 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();
   

StringWriter writer = new StringWriter();
get_Server().UrlDecode(encodedString, writer);
String decodedString = writer.ToString();

var writer : StringWriter = new StringWriter()
Server.UrlDecode(encodedString, writer)
var decodedString : String = writer.ToString()
