When overridden in a derived class, reads a specified number of characters from a specified column starting at a specified index, and writes them to a buffer starting at a specified position.
public:
abstract long GetChars(int ordinal, long dataOffset, cli::array <char> ^ buffer, int bufferOffset, int length);
public abstract long GetChars (int ordinal, long dataOffset, char[] buffer, int bufferOffset, int length);
public abstract long GetChars (int ordinal, long dataOffset, char[]? buffer, int bufferOffset, int length);
abstract member GetChars : int * int64 * char[] * int * int -> int64
Public MustOverride Function GetChars (ordinal As Integer, dataOffset As Long, buffer As Char(), bufferOffset As Integer, length As Integer) As Long
Parameters

- buffer
- Char[]
The buffer into which to copy the data.
- bufferOffset
- Int32
The index with the buffer to which the data will be copied.
- length
