Encoding::Unicode Property
Gets an encoding for the UTF-16 format using the little endian byte order.
Assembly: mscorlib (in mscorlib.dll)
Property Value
Type: System.Text::Encoding^An encoding for the UTF-16 format using the little endian byte order.
For information about the encodings supported by the .NET Framework and a discussion of which Unicode encoding to use, see Character Encoding in the .NET Framework.
The UnicodeEncoding object that is returned by this property may not have the appropriate behavior for your app. It uses replacement fallback to replace each string that it cannot encode and each byte that it cannot decode with a question mark ("?") character. Instead, you can call the UnicodeEncoding::UnicodeEncoding(Boolean, Boolean, Boolean) constructor to instantiate a little endian UnicodeEncoding object whose fallback is either an EncoderFallbackException or a DecoderFallbackException, as the following example illustrates.
The following example determines the number of bytes required to encode a character array, encodes the characters, and displays the resulting bytes.
using namespace System; using namespace System::Text; void PrintCountsAndBytes( array<Char>^chars, Encoding^ enc ); void PrintHexBytes( array<Byte>^bytes ); int main() { // The characters to encode: // Latin Small Letter Z (U+007A) // Latin Small Letter A (U+0061) // Combining Breve (U+0306) // Latin Small Letter AE With Acute (U+01FD) // Greek Small Letter Beta (U+03B2) // a high-surrogate value (U+D8FF) // a low-surrogate value (U+DCFF) array<Char>^myChars = gcnew array<Char>{ L'z','a',L'\u0306',L'\u01FD',L'\u03B2',L'\xD8FF',L'\xDCFF' }; // Get different encodings. Encoding^ u7 = Encoding::UTF7; Encoding^ u8 = Encoding::UTF8; Encoding^ u16LE = Encoding::Unicode; Encoding^ u16BE = Encoding::BigEndianUnicode; Encoding^ u32 = Encoding::UTF32; // Encode the entire array, and print out the counts and the resulting bytes. PrintCountsAndBytes( myChars, u7 ); PrintCountsAndBytes( myChars, u8 ); PrintCountsAndBytes( myChars, u16LE ); PrintCountsAndBytes( myChars, u16BE ); PrintCountsAndBytes( myChars, u32 ); } void PrintCountsAndBytes( array<Char>^chars, Encoding^ enc ) { // Display the name of the encoding used. Console::Write( "{0,-30} :", enc ); // Display the exact byte count. int iBC = enc->GetByteCount( chars ); Console::Write( " {0,-3}", iBC ); // Display the maximum byte count. int iMBC = enc->GetMaxByteCount( chars->Length ); Console::Write( " {0,-3} :", iMBC ); // Encode the array of chars. array<Byte>^bytes = enc->GetBytes( chars ); // Display all the encoded bytes. PrintHexBytes( bytes ); } void PrintHexBytes( array<Byte>^bytes ) { if ( (bytes == nullptr) || (bytes->Length == 0) ) Console::WriteLine( "<none>" ); else { for ( int i = 0; i < bytes->Length; i++ ) Console::Write( "{0:X2} ", bytes[ i ] ); Console::WriteLine(); } } /* This code produces the following output.
