The DecoderFallback object represents an error handler that is invoked when an encoded byte sequence cannot be decoded into a character. Any one of the following handler types is supported:
A best-fit fallback handler, which replaces bytes that cannot be decoded with some suitable replacement character.
A replacement fallback handler, which replaces bytes that cannot be decoded with some arbitrary replacement character. The .NET Framework includes one replacement fallback handler, DecoderFallback, which by default replaces bytes that cannot be decoded with a question mark ("?") character.
An exception fallback handler, which throws an exception when bytes cannot be decoded. The .NET Framework includes one exception fallback handler, DecoderExceptionFallback, which throws a DecoderFallbackException when bytes cannot be decoded.
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows XP SP2 x64 Edition, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
