Method-Based Query Examples (LINQ to DataSet)

This section provides LINQ to DataSet programming examples in method-based query 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.

Method-Based Query Syntax Examples: Projection (LINQ to DataSet)

The examples in this topic demonstrate how to use the Select and SelectMany methods to query a DataSet.

Method-Based Query Syntax Examples: Partitioning (LINQ

The examples in this topic demonstrate how to use the Skip<TSource> and Take<TSource> methods to query a DataSet and partition the results.

Method-Based Query Syntax Examples: Ordering (LINQ to DataSet)

The examples in this topic demonstrate how to use the OrderBy, OrderByDescending, Reverse<TSource>, and ThenByDescending methods to query a DataSet and order the results.

Method-Based Query Syntax Examples: Set Operators (LINQ to DataSet)

The examples in this topic demonstrate how to use the Distinct, Except, Intersect, and Union operators to perform value-based comparison operations on sets of data rows.

Method-Based Query Syntax Examples: Conversion Operators (LINQ to DataSet)

The examples in this topic demonstrate how to use the ToArray<TSource>, ToDictionary, and ToList<TSource> methods to immediately execute a query expression.

Method-Based Query Syntax Examples: Element Operators (LINQ to DataSet)

The examples in this topic demonstrate how to use the First and ElementAt<TSource> methods to get DataRow elements from a DataSet.

Method-Based Query Syntax Examples: Aggregate Operators (LINQ to DataSet)

The examples in this topic demonstrate how to use the Average, Count, Max, Min, and Sum methods to query a DataSet and aggregate data.

Method-Based Query Syntax Examples: Join (LINQ to DataSet)

The examples in this topic demonstrate how to use the GroupJoin and Join methods to query a DataSet.
