参数
- ordinal
类型：System.Int32
An Int32 value that specifies the column position at which to retrieve the character array value.
- buffer
类型：array<System.Char[]
A Uint8 array that specifies the buffer into which to read the character array.
- length
类型：System.Int32
An Int32 value that specifies the number of characters to read.
- bufferoffset
类型：System.Int32
An Int32 value that specifies the index from which to start the read operation.
- fieldoffset
类型：System.Int32
An Int32 value that specifies the index position within the record from which to begin the read operation.
返回值
类型：System.Int32
An int32 value that specifies the number of characters returned in the array.
