WebUtility.HtmlDecode Method (String, TextWriter)

.NET Framework (current version)

Converts a string that has been HTML-encoded into a decoded string, and sends the decoded string to a TextWriter output stream.

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

public static void HtmlDecode(
	string value,
	TextWriter output


Type: System.String

The string to decode.

Type: System.IO.TextWriter

A TextWriter stream of output.

Exception Condition

The output parameter cannot be null if the value parameter is not null.

If characters such as blanks and punctuation are passed in an HTTP stream, they might be misinterpreted at the receiving end. HTML encoding converts characters that are not allowed in HTML into character-entity equivalents; HTML decoding reverses the encoding. For example, when embedded in a block of text, the characters < and > are encoded as &lt; and &gt; for HTTP transmission.
