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

ordinal: Int32

The zero-based column ordinal.

dataOffset: Int64

The index within the row from which to begin the read operation.

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: Int32

The maximum number of characters to read.

Returns

Int64

The actual number of characters read.
