Methods

AsEnumerable<TRow>(TypedTableBase<TRow>)	Enumerates the data row elements of the TypedTableBase<T> and returns an EnumerableRowCollection<TRow> object, where the generic parameter T is DataRow. This object can be used in a LINQ expression or method query.
ElementAtOrDefault<TRow>(TypedTableBase<TRow>, Int32)	Returns the element at a specified row in a sequence or a default value if the row is out of range.
OrderBy<TRow,TKey>(TypedTableBase<TRow>, Func<TRow,TKey>)	Sorts the rows of a TypedTableBase<T> in ascending order according to the specified key.
OrderBy<TRow,TKey>(TypedTableBase<TRow>, Func<TRow,TKey>, IComparer<TKey>)	Sorts the rows of a TypedTableBase<T> in ascending order according to the specified key and comparer.
OrderByDescending<TRow,TKey>(TypedTableBase<TRow>, Func<TRow,TKey>)	Sorts the rows of a TypedTableBase<T> in descending order according to the specified key.
OrderByDescending<TRow,TKey>(TypedTableBase<TRow>, Func<TRow,TKey>, IComparer<TKey>)	Sorts the rows of a TypedTableBase<T> in descending order according to the specified key and comparer.
Select<TRow,S>(TypedTableBase<TRow>, Func<TRow,S>)	Projects each element of a TypedTableBase<T> into a new form.
Where<TRow>(TypedTableBase<TRow>, Func<TRow,Boolean>)	Filters a sequence of rows based on the specified predicate.
