WebUtility.UrlDecodeToBytes(Byte[], Int32, Int32) Method

Definition

Namespace:

System.Net

Assembly:

System.Runtime.dll

Source:

WebUtility.cs

Converts an encoded byte array that has been encoded for transmission in a URL into a decoded byte array.

public:
 static cli::array <System::Byte> ^ UrlDecodeToBytes(cli::array <System::Byte> ^ encodedValue, int offset, int count);

public static byte[]? UrlDecodeToBytes (byte[]? encodedValue, int offset, int count);

static member UrlDecodeToBytes : byte[] * int * int -> byte[]

Public Shared Function UrlDecodeToBytes (encodedValue As Byte(), offset As Integer, count As Integer) As Byte()

Parameters

encodedValue

Byte[]

A URL-encoded Byte array to decode.

offset

Int32

The offset, in bytes, from the start of the Byte array to decode.

count

Int32

The count, in bytes, to decode from the Byte array.

Returns

Byte[]

A decoded Byte array.

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 UrlEncodeToBytes method creates a URL-encoded byte array.

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 >.
