Encoding.GetChars Method (Byte*, Int32, Char*, Int32)
Assembly: mscorlib (in mscorlib.dll)
[ComVisibleAttribute(false)] [CLSCompliantAttribute(false)] public: virtual int GetChars ( unsigned char* bytes, int byteCount, wchar_t* chars, int charCount )
A pointer to the first byte to decode.
The number of bytes to decode.
A pointer to the location at which to start writing the resulting set of characters.
The maximum number of characters to write.
Return ValueThe actual number of characters written at the location indicated by the chars parameter.
bytes is a null reference (Nothing in Visual Basic).
chars is a null reference (Nothing in Visual Basic).
byteCount or charCount is less than zero.
charCount is less than the resulting number of characters.
A fallback occurred (see Understanding Encodings for complete explanation)
To calculate the exact array size that GetChars requires to store the resulting characters, the application should use GetCharCount. To calculate the maximum array size, the application should use GetMaxCharCount. The GetCharCount method generally allows allocation of less memory, while the GetMaxCharCount method generally executes faster.
If the data to be converted is available only in sequential blocks (such as data read from a stream) or if the amount of data is so large that it needs to be divided into smaller blocks, the application should use the Decoder or the Encoder object provided by the GetDecoder or the GetEncoder method, respectively, of a derived class.
Note This method is intended to operate on Unicode characters, not on arbitrary binary data, such as byte arrays. If your application needs to encode arbitrary binary data into text, it should use a protocol such as uuencode, which is implemented by methods such as System.Convert.ToBase64CharArray.
For a discussion of programming considerations for use of this method, see the Encoding class description.
