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