Definition

Namespace:

System.Net

Assembly:

System.Runtime.dll

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

Overloads

HtmlDecode(String)	Converts a string that has been HTML-encoded for HTTP transmission into a decoded string.
HtmlDecode(String, TextWriter)	Converts a string that has been HTML-encoded into a decoded string, and sends the decoded string to a TextWriter output stream.

HtmlDecode(String)

Source:

WebUtility.cs

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

public:
 static System::String ^ HtmlDecode(System::String ^ value);

public static string? HtmlDecode (string? value);

static member HtmlDecode : string -> string

Public Shared Function HtmlDecode (value As String) As String

Parameters

value

String

The string to decode.

Returns

String

A decoded string.

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.

If the value parameter is null, then the returned decoded string is null. If the value parameter is an empty string, then the returned decoded string is an empty string.
