HttpUtility.UrlDecode Method (Byte(), Encoding)

Converts a URL-encoded byte array into a decoded string using the specified decoding object.

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

'Declaration
Public Shared Function UrlDecode ( _
	bytes As Byte(), _
	e As Encoding _
) As String

Parameters

bytes
Type: System.Byte()

The array of bytes to decode.

e
Type: System.Text.Encoding

The Encoding that specifies the decoding scheme.

Return Value

Type: System.String
A decoded string.

If characters such as blanks and punctuation are passed in an HTTP stream, they might be misinterpreted at the receiving end. URL encoding converts characters that are not allowed in a URL into character-entity equivalents; URL decoding reverses the encoding. For example, when embedded in a block of text to be transmitted in a URL, the characters < and > are encoded as %3c and %3e.

To encode or decode values outside of a web application, use the WebUtility class.
