Microsoft Silverlight will reach end of support after October 2021. Learn more.

Converts a string that has been encoded for transmission in a URL into a decoded string.

Namespace:  System.Windows.Browser
Assembly:  System.Windows.Browser (in System.Windows.Browser.dll)

Syntax

'Declaration
Public Shared Function UrlDecode ( _
    url As String _
) As String

public static string UrlDecode(
    string url
)

Parameters

Return Value

Type: System.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. URL encoding converts characters that are not allowed in a URL into equivalent hexadecimal escape sequences. The UrlEncode method creates a URL-encoded string.

URL decoding replaces hexadecimal escape sequences with corresponding ASCII character equivalents. For example, when embedded in a block of URL-encoded text, the escape sequences %3c and %3e are decoded into the characters < and >.
