Description
Returns the number of bytes generated by encoding the passed characters.
Returns the number of bytes generated by encoding Chars. Note that the number of bytes in a string is not necessarily exactly proportional to the number of characters in a given character array or string. A character in UTF-16 encoded strings is 2 bytes wide.
The following table lists the parameters expected by this method and their description.
| Parameter | Description |
|---|---|
|
Chars |
A character array or a character pointer containing the bytes to be counted. |
|
CharCount |
Specifies the number of characters to encode. |
The return value is the number of bytes in the passed Chars parameter.
