static member UrlDecode : string -> string
Public Shared Function UrlDecode (encodedValue As String) As String



A URL-encoded string to decode.


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 equivalent hexadecimal escape sequences. The hexadecimal escape sequences are in uppercase. For example, the characters < and > are encoded into the escape sequences %3C and %3E. 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 >.
