参数
- i
类型：System.Int32
The zero-based column ordinal.
- fieldoffset
类型：System.Int64
The index within the field from which to begin the read operation.
- buffer
类型：array<System.Char[]
The buffer into which to read the stream of bytes.
- bufferoffset
类型：System.Int32
The index within the buffer where the write operation is to start.
- length
类型：System.Int32
The maximum length to copy into the buffer.
返回值
类型：System.Int64
The number of characters read.
实现
IDataRecord.GetChars(Int32, Int64, array<Char[], Int32, Int32)
