DataRow Field Operators

In addition to the DataRow-specific comparer class for the set-type operators, there is a need for some DataRow-specific operators. These operators are defined in the System.Data.DataSetExtensions.dll assembly, in the static System.Data.DataRowExtensions class.

You have no doubt noticed that in virtually every example thus far, I have used the Field<T> operator to extract a DataColumn object's value from a DataRow. There are two purposes for this operator: correct equality comparisons and null value handling.
