 abstract long GetChars(int i, long dataIndex, cli::array <char> ^ buffer, int bufferIndex, int length);

public:
 virtual long GetChars(int i, long dataIndex, cli::array <char> ^ buffer, int bufferIndex, int length);

public abstract long GetChars (int i, long dataIndex, char[] buffer, int bufferIndex, int length);

public abstract long GetChars (int i, long dataIndex, char[]? buffer, int bufferIndex, int length);

public long GetChars (int i, long dataIndex, char[] buffer, int bufferIndex, int length);

Public MustOverride Function GetChars (i As Integer, dataIndex As Long, buffer As Char(), bufferIndex As Integer, length As Integer) As Long

Public Function GetChars (i As Integer, dataIndex As Long, buffer As Char(), bufferIndex As Integer, length As Integer) As Long

列序号。

要将数据复制到其中的缓冲区。

复制到缓冲区的最大长度。

从缓冲区中开始的点。

从数据源中开始的点。

Int64

指定列的值。

不执行任何转换，因此检索的数据必须已经是字符数组。
