Converts a URL-encoded string or byte array into a decoded array of bytes.

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

Overloads

UrlDecodeToBytes(Byte[])

Converts a URL-encoded array of bytes into a decoded array of bytes.
UrlDecodeToBytes(String)

Converts a URL-encoded string into a decoded array of bytes.
UrlDecodeToBytes(String, Encoding)

Converts a URL-encoded string into a decoded array of bytes using the specified decoding object.
UrlDecodeToBytes(Byte[], Int32, Int32)

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

UrlDecodeToBytes(Byte[])

Source:
HttpUtility.cs
Source:
HttpUtility.cs
Source:
HttpUtility.cs

Converts a URL-encoded array of bytes into a decoded array of bytes.

public:
 static cli::array <System::Byte> ^ UrlDecodeToBytes(cli::array <System::Byte> ^ bytes);
public static byte[]? UrlDecodeToBytes (byte[]? bytes);
public static byte[] UrlDecodeToBytes (byte[] bytes);
static member UrlDecodeToBytes : byte[] -> byte[]
Public Shared Function UrlDecodeToBytes (bytes As Byte()) As Byte()

Parameters

bytes
Byte[]

The array of bytes to decode.

Returns

Byte[]

A decoded array of bytes.

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 WebUtility class.
