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.
