Parameters

bytes

A byte array to decode.

index

A int that specifies the first index in bytes to decode.

count

A int that specifies the number elements in bytes to decode.

Returns

A int containing the number of characters the next call to Decoder.GetChars(Byte[], int, int, Char[], int) will produce if presented with the specified range of bytes .

Note: This value takes into account the state in which the current instance was left following the last call to Decoder.GetChars(Byte[], int, int, Char[], int). This contrasts with Encoding.GetChars(Byte[]), which does not maintain state information across subsequent calls.

Exceptions

Type	Reason
ArgumentNullException	bytes is null .
ArgumentOutOfRangeException	index < 0. -or- count < 0. -or- index and count do not specify a valid range in bytes (i.e. (index + count) > bytes.Length).

Remarks

Operation

As described above.

Note to Inheritors

Override this method to return the appropriate value for a particular encoding.

Usage

Use this method to determine the appropriate size of a buffer to contain the decoded values.
