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.
