Remarks
For most applications, the GetValues method provides an efficient means for retrieving all columns, rather than retrieving each column individually.
You can pass an Object array that contains fewer than the number of columns contained in the resulting row. Only the amount of data the Object array holds is copied to the array. You can also pass an Object array whose length is more than the number of columns contained in the resulting row.
This method returns DBNull for null database columns.
