HttpServerUtility.HtmlEncode Method (String)

HTML-encodes a string and returns the encoded string.

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

public string HtmlEncode(
	string s
)

Parameters

s
Type: System.String
The text string to encode.

Return Value

Type: System.String
The HTML-encoded text.

HTML encoding makes sure that text is displayed correctly in the browser and not interpreted by the browser as HTML. For example, if a text string contains a less than sign (<) or greater than sign (>), the browser would interpret these characters as the opening or closing bracket of an HTML tag. When the characters are HTML encoded, they are converted to the strings &lt; and &gt;, which causes the browser to display the less than sign and greater than sign correctly.

The HtmlEncode method is a convenient way to access the HttpUtility.HtmlEncode method at run time from an ASP.NET application. Internally, HtmlEncode uses HttpUtility.HtmlEncode to encode strings.

The following example encodes a string for transmission by HTTP. It encodes the string named TestString, which contains the text "This is a <Test String>.", and copies it into the string named EncodedString as "This is a &lt;Test String&gt;.".


String TestString = "This is a <Test String>.";
String EncodedString = Server.HtmlEncode(TestString);
