.NET Framework Class Library
HttpUtility.HtmlEncode Method (String, TextWriter)
Converts a string into an HTML-encoded string, and returns the output as a TextWriter stream of output.
Assembly: System.Web (in System.Web.dll)
Syntax
Visual Basic
Public Shared Sub HtmlEncode ( _ s As String, _ output As TextWriter _ )
C#
public static void HtmlEncode( string s, TextWriter output )
Visual C++
public: static void HtmlEncode( String^ s, TextWriter^ output )
F#
static member HtmlEncode : s:string * output:TextWriter -> unit
Parameters
- s
- Type: System.String
The string to encode
- output
- Type: System.IO.TextWriter
A TextWriter output stream.
Remarks
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 < and > for HTTP transmission.
