Property Value

Type: System.Text::Encoding
An encoding for the UTF-8 format.

This property returns a UTF8Encoding object that encodes Unicode characters into a sequence of one to four bytes per character, and that decodes a UTF-8-encoded byte array to Unicode characters. For information about the character encodings supported by the .NET Framework and a discussion of which Unicode encoding to use, see Understanding Encodings.

The UTF8Encoding object that is returned by this property may not have the appropriate behavior for your application. 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 UTF8Encoding::UTF8Encoding(Boolean, Boolean) constructor to instantiate a UTF8Encoding object whose fallback is either an EncoderFallbackException or a DecoderFallbackException, as the following example illustrates.

No code example is currently available or this language may not be supported.

The following code example determines the number of bytes required to encode a character array, encodes the characters, and displays the resulting bytes.
