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

Note: This method is new in the .NET Framework version 2.0.

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

This method is not CLS-compliant.  

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

[ComVisibleAttribute(false)] 
[CLSCompliantAttribute(false)] 
public virtual int GetChars (
	byte* bytes,
	int byteCount,
	char* chars,
	int charCount
)
J# does not support APIs that consume or return unsafe types.
JScript does not support APIs that consume or return unsafe types.

Parameters

bytes

A pointer to the first byte to decode.

byteCount

The number of bytes to decode.

chars

A pointer to the location at which to start writing the resulting set of characters.

charCount

The maximum number of characters to write.

Return Value

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

Exception typeCondition

ArgumentNullException

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

-or-

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

ArgumentOutOfRangeException

byteCount or charCount is less than zero.

ArgumentException

charCount is less than the resulting number of characters.

To calculate the exact array size that GetChars requires to store the resulting characters, use GetCharCount. To calculate the maximum array size, use GetMaxCharCount. The GetCharCount method generally allows you to allocate less memory, whereas 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, use the Decoder or the Encoder object provided by the GetDecoder or the GetEncoder method, respectively, of a derived class.
