System.Web.HttpUtility.UrlDecode Method

Converts a URL-encoded byte array into a decoded string using the specified encoding object, starting at the specified position in the array, and continuing for the specified number of bytes.

Syntax

public static string UrlDecode (byte[] bytes, int offset, int count, System.Text.Encoding e)

Parameters

bytes
The array of bytes to decode.
offset
The position in the byte to begin decoding.
count
The number of bytes to decode.
e
The System.Text.Encoding object that specifies the decoding scheme.

Returns

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 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 System.Net.WebUtility class.
