 During the serialization of data reader, most of code uses column name
 instead of column index, for example, get column type, check null, get
 data.
 Actually as the final purpose is to return the whole dataset, there is no
 such situation that a column exists in dataset but not serialized, also
 the sequence of property is exactly the same with the sequence of column.
 So the serialization can be optimized to use column index to reduce column
 searching.
