以下只是示例,如有其它业务需求,可添加参数自己扩展
public static IEnumerable<T> GetOrderEnum<T>(this IEnumerable<T> source, Func<IEnumerable<T>, IOrderedEnumerable<T>> func) { return func(source); } public static IEnumerable<T> GetOrderEnum<T>(this IEnumerable<T> source, Func<T, IComparable> func, bool isAsc) { return isAsc ? source.OrderBy(func) : source.OrderByDescending(func); } public static IEnumerable<T> GetOrderEnum<T, K>(this IEnumerable<T> source, Func<T, K> func, bool isAsc) { return isAsc ? source.OrderBy(func) : source.OrderByDescending(func); } public static IEnumerable<T> GetOrderEnum<T>(this IEnumerable<T> source, string propertyName, bool isAsc) { ParameterExpression para = Expression.Parameter(typeof(T)); var proper = Expression.Property(para, propertyName); dynamic expression = Expression.Lambda(proper, para); return isAsc ? Queryable.OrderBy(source.AsQueryable(), expression) : Queryable.OrderByDescending(source.AsQueryable(), expression); }
如果还有其它方法,请留言,以便交流!
