Encoding.GetBytes Method (Char*, Int32, Byte*, Int32)

When overridden in a derived class, encodes a set of characters starting at the specified character pointer into a sequence of bytes that are stored starting at the specified byte pointer.

This method is not CLS-compliant.  

Namespace: System.Text
Assembly: mscorlib (in mscorlib.dll)

[ComVisibleAttribute(false)] 
[CLSCompliantAttribute(false)] 
public virtual int GetBytes (
	char* chars,
	int charCount,
	byte* bytes,
	int byteCount
)
Not applicable.

Parameters

chars

A pointer to the first character to encode.

charCount

The number of characters to encode.

bytes

A pointer to the location at which to start writing the resulting sequence of bytes.

byteCount

The maximum number of bytes to write.

Return Value

The actual number of bytes written at the location indicated by the bytes parameter.

Exception typeCondition

ArgumentNullException

chars is a null reference (Nothing in Visual Basic).

-or-

bytes is a null reference (Nothing in Visual Basic).

ArgumentOutOfRangeException

charCount or byteCount is less than zero.

ArgumentException

byteCount is less than the resulting number of bytes.

EncoderFallbackException

A fallback occurred (see Understanding Encodings for complete explanation)

-and-

EncoderFallback is set to EncoderExceptionFallback.

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.
