Parameters
- charCount

Returns
A int containing the maximum number of bytes required to encode charCount characters as ASCII-encoded characters.
Exceptions
Type Reason ArgumentOutOfRangeException charCount < 0.
Remarks
Note:This method overrides Encoding.GetMaxByteCount(int) .
Use this method to determine a minimum buffer size for byte arrays passed to the ASCIIEncoding.GetBytes(Char[], int, int, Byte[], int) or Encoding.GetBytes(Char[]) method for the current instance. Using this minimum buffer size can help ensure that buffer overflow exceptions do not occur.
