HttpServerUtility.HtmlDecode Method (String, TextWriter)

Decodes an HTML-encoded string and sends the resulting output to a TextWriter output stream.

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

public void HtmlDecode (
	string s,
	TextWriter output
public void HtmlDecode (
	String s, 
	TextWriter output
public function HtmlDecode (
	s : String, 
	output : TextWriter



The HTML string to decode.


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.

HtmlDecode decodes text that has been transmitted to the server.

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

The following code example decodes a string that has been HTML-encoded for transmission over HTTP. It decodes the supplied string named EncodedString which contains the text "This is a &ltTest String&gt.", and copies it into the string named DecodedString as "This is a <Test String>."

String EncodedString = "This is a &ltTest String&gt.";
StringWriter writer = new StringWriter();
Server.HtmlDecode(EncodedString, writer);
String DecodedString = writer.ToString();

String encodedString = "This is a &ltTest String&gt.";
StringWriter writer = new StringWriter();
get_Server().HtmlDecode(encodedString, writer);
String decodedString = writer.ToString();

var encodedString : String = "This is a &ltTest String&gt."
var writer : StringWriter = new StringWriter()
Server.HtmlDecode(encodedString, writer)
var decodedString : String = writer.ToString()
