It lists each encoding's code page number and the values of the encoding's EncodingInfo.Name and EncodingInfo.DisplayName properties. The following table lists the encodings supported by. Use the GetEncoding method to obtain other encodings, and call the GetEncodings method to get a list of all encodings. Often one of the derived Unicode classes is the correct choice for your app. The Encoding class is primarily intended to convert between different encodings and Unicode. Also available through the UTF32 property. Both little endian (code page 12000) and big endian (code page 12001) byte orders are supported.
UTF32Encoding encodes Unicode characters using the UTF-32 encoding. Also available through the Unicode property and the BigEndianUnicode property. Both little endian and big endian byte orders are supported. UnicodeEncoding encodes Unicode characters using the UTF-16 encoding. Also available through the UTF8 property. This encoding supports all Unicode character values. UTF8Encoding encodes Unicode characters using the UTF-8 encoding. Also available through the UTF7 property. UTF7Encoding encodes Unicode characters using the UTF-7 encoding. Also available through the ASCII property. This encoding only supports character values between U+0000 and U+007F. NET provides the following implementations of the Encoding class to support current Unicode encodings and other encodings:ĪSCIIEncoding encodes Unicode characters as single 7-bit ASCII characters. If you must encode arbitrary binary data into text, you should use a protocol such as uuencode, which is implemented by methods such as Convert.ToBase64CharArray. Note that Encoding is intended to operate on Unicode characters instead of arbitrary binary data, such as byte arrays. For information about the Unicode Transformation Formats (UTFs) and other encodings supported by Encoding, see Character Encoding in.
In contrast, decoding is the process of transforming a sequence of encoded bytes into a set of Unicode characters. ' Ascii converted string: This string contains the unicode character Pi (?)Įncoding is the process of transforming a set of Unicode characters into a sequence of bytes. ' Original string: This string contains the unicode character Pi (Π) ' The example displays the following output: Display the strings created before and after the conversion.Ĭonsole::WriteLine( "Original String*: ", asciiString) String^ asciiString = gcnew String( asciiChars ) Convert the new Byte into a char and then into a string.Īrray^asciiChars = gcnew array(ascii->GetCharCount( asciiBytes, 0, asciiBytes->Length )) Īscii->GetChars( asciiBytes, 0, asciiBytes->Length, asciiChars, 0 ) Perform the conversion from one encoding to the other.Īrray^asciiBytes = Encoding::Convert( unicode, ascii, unicodeBytes ) String^ unicodeString = "This string contains the unicode character Pi (\u03a0)" Īrray^unicodeBytes = unicode->GetBytes( unicodeString ) NET Char and String types are themselves Unicode, so the GetChars call decodes the data back to Unicode. The byte array is the only type in this example that contains the encoded data.
