Parameters

bytes

The byte array containing the sequence of bytes to decode.

index

The index of the first byte to decode.

count

The number of bytes to decode.

Returns

The number of characters produced by decoding the specified sequence of bytes.

Exceptions

Type	Reason
ArgumentNullException	bytes is null.
ArgumentOutOfRangeException	index < 0. -or- count < 0. -or- (bytes.Length - index) < count.

Remarks

To calculate the exact array size required by ASCIIEncoding.GetChars(Byte[], int, int, Char[], int) to store the resulting characters, the application uses ASCIIEncoding.GetCharCount(Byte[], int, int). To calculate the maximum array size, the application should use ASCIIEncoding.GetMaxCharCount(int). The ASCIIEncoding.GetCharCount(Byte[], int, int) method generally allows allocation of less memory, while the ASCIIEncoding.GetMaxCharCount(int) method generally executes faster.
