<Extension()>
Public Function OrderByDescending(Of TRow As DataRow, TKey As DataRow) (source As TypedTableBase(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

TypedTableBase<TRow>

A TypedTableBase<T> that contains 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.
