EDBDataReader Class

The EDBDataReader class implements the DbDataReader abstract class, providing an encapsulation of a data reader object for enumerating the result set of an EDBCommand instance.

In addition to the normal Get* methods that use column indexes to retrieve column data, there are also matching Get* methods that accept a column name instead of a column index. The only difference in the method parameters for these methods is the first parameter, which is a String instead of an Int32.
