Encoding.GetBytes Method (Char*, Int32, Byte*, Int32)
Assembly: mscorlib (in mscorlib.dll)
[ComVisibleAttribute(false)] [CLSCompliantAttribute(false)] public virtual int GetBytes ( char* chars, int charCount, byte* bytes, int byteCount )
A pointer to the first character to encode.
The number of characters to encode.
A pointer to the location at which to start writing the resulting sequence of bytes.
The maximum number of bytes to write.
Return ValueThe actual number of bytes written at the location indicated by the bytes parameter.
chars is a null reference (Nothing in Visual Basic).
bytes is a null reference (Nothing in Visual Basic).
charCount or byteCount is less than zero.
byteCount is less than the resulting number of bytes.
A fallback occurred (see Understanding Encodings for complete explanation)
To calculate the exact array size that GetBytes requires to store the resulting bytes, the application should use GetByteCount. To calculate the maximum array size, the application should use GetMaxByteCount. The GetByteCount method generally allows allocation of less memory, while the GetMaxByteCount 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.
For a discussion of programming considerations for use of this method, see the Encoding class description.
