HttpUtility.HtmlDecode Method (String)

Converts a string that has been HTML-encoded for HTTP transmission into a decoded string.

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

static String^ HtmlDecode (
	String^ s
public static String HtmlDecode (
	String s
public static function HtmlDecode (
	s : String
) : String



The string to decode.

Return Value

A decoded string.

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.

The following code example demonstrates the HtmlEncode and HtmlDecode methods of the HttpUtility class. The input string is encoded using the HtmlEncode method. The encoded string obtained is then decoded using the HtmlDecode method.

        String myEncodedString;
        // Encode the string.
        myEncodedString = HttpUtility.HtmlEncode(myString);
        Console.WriteLine("HTML Encoded string is " + myEncodedString);
        StringWriter myWriter =  new StringWriter();
        // Decode the encoded string.
        HttpUtility.HtmlDecode(myEncodedString, myWriter);
        Console.Write("Decoded string of the above encoded string is " 
            + myWriter.ToString());
    } //main
} //MyNewClass
