HttpUtility::HtmlAttributeEncode Method (String, TextWriter)

Minimally converts a string into an HTML-encoded string and sends the encoded string to a TextWriter output stream.

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

public:
static void HtmlAttributeEncode(
	String^ s, 
	TextWriter^ output
)

Parameters

s
Type: System::String

The string to encode

output
Type: System.IO::TextWriter

A TextWriter output stream.

The HtmlAttributeEncode method converts only quotation marks ("), ampersands (&), and left angle brackets (<) to equivalent character entities. It is considerably faster than the HtmlEncode method.

The string result from the HtmlAttributeEncode method should be used only for double-quoted attributes. Security issues might arise when using the HtmlAttributeEncode method with single-quoted attributes.
