参数

  • fieldoffset
    类型:System.Int64
    The index within the row from which to begin the read operation.
  • buffer
    类型:array<System.Char[]
    The buffer into which to copy the data.
  • bufferoffset
    类型:System.Int32
    The index with the buffer to which the data will be copied.
  • length
    类型:System.Int32
    The maximum number of characters to read.

返回值

类型:System.Int64
The actual number of characters read.

实现

IDataRecord.GetChars(Int32, Int64, array<Char[], Int32, Int32)
