public:
generic <typename TRow, typename TKey>
[System::Runtime::CompilerServices::Extension]
 static System::Data::OrderedEnumerableRowCollection<TRow> ^ OrderBy(System::Data::EnumerableRowCollection<TRow> ^ source, Func<TRow, TKey> ^ keySelector);

static member OrderBy : System.Data.EnumerableRowCollection<'Row> * Func<'Row, 'Key> -> System.Data.OrderedEnumerableRowCollection<'Row>
<Extension()>
Public Function OrderBy(Of TRow, TKey) (source As EnumerableRowCollection(Of TRow), keySelector As Func(Of TRow, TKey)) As OrderedEnumerableRowCollection(Of TRow)

Type Parameters

TRow

The type of the row elements in source, typically DataRow.

TKey

The type of the key returned by keySelector.

Parameters

source
EnumerableRowCollection<TRow>

An EnumerableRowCollection containing the DataRow elements to be ordered.

keySelector
Func<TRow,TKey>

A function to extract a key from an element.

Returns

OrderedEnumerableRowCollection<TRow>

An OrderedEnumerableRowCollection<TRow> whose elements are sorted by the specified key.

Remarks

This method is implemented by using deferred execution. The immediate return value is an object that stores all the information that is required to perform the action. The query represented by this method is not executed until the object is enumerated either by calling its GetEnumerator method directly or by using foreach in Visual C# or For Each in Visual Basic.
