参数
- ordinal
类型：System.Int32
An Int32 value that specifies the column position at which to retrieve the character array value.
- fieldoffset
类型：System.Int64
An Int32 value that specifies the index position within the record from which to begin the read operation.
- buffer
类型：array<System.Char[]
A Uint8 array that specifies the buffer into which to read the character array.
- bufferoffset
类型：System.Int32
An Int32 value that specifies the index from which to start the read operation.
- length
类型：System.Int32
An Int32 value that specifies the number of characters to read.
返回值
类型：System.Int64
An Int64 value that specifies the number of characters returned in the array.
实现
IDataRecord.GetChars(Int32, Int64, array<Char[], Int32, Int32)
