[C# Talk] : A smarter OrderBy<> and OrderByDescendnig<>
Hvordan undgår man at blive nød til at kalde skiftevis OrderBy<> og OrderByDescendnig<> når man laver en custom sorting-algoritme i sit business lag i en Linq-baseret applikation? Man laver da naturligvis en extension method!
public static class ExtensionMethods
{
public static IOrderedQueryable<TSource>
OrderByDirection<TSource,TKey>(this IQueryable<TSource> source, Expression<Func<TSource, TKey>> keySelector, SortDirection sortDirection)
{
return sortDirection == SortDirection.Ascending ?
source.OrderBy(keySelector) :
source.OrderByDescending(keySelector);
}
}
