Query Expression Examples (LINQ to DataSet)

This section provides LINQ to DataSet programming examples in query expression syntax that use the standard query operators. The DataSet used in these examples is populated by using the FillDataSet method, which is specified in Loading Data Into a DataSet. For more information, see Standard Query Operators Overview.
