Record. Get Chars(Int32, Int64, Char, Int32, Int32) Method
Reads a stream of characters from the specified column offset into the buffer as an array, starting at the given buffer offset.
public: long GetChars(int i, long fieldoffset, cli::array <char> ^ buffer, int bufferoffset, int length);
public long GetChars (int i, long fieldoffset, char buffer, int bufferoffset, int length);
abstract member GetChars : int * int64 * char * int * int -> int64
Public Function GetChars (i As Integer, fieldoffset As Long, buffer As Char(), bufferoffset As Integer, length As Integer) As Long
The zero-based column ordinal.
The index within the row from which to start the read operation.
The buffer into which to read the stream of bytes.
The index for
buffer to start the read operation.
The number of bytes to read.
The actual number of characters read.
GetChars returns the number of available characters in the field. Frequently this is the exact length of the field. However, the number returned may be less than the exact length of the field if
GetChars has already been used to obtain characters from the field.
If you pass a buffer that is
GetChars returns the length of the field in characters.
No conversions are performed; therefore the data retrieved must already be a character array.
