Question

我正在检索一个LINQ查询，虽然在其上下文中我将如何对输出进行排序，我已经尝试过sortby等但无济于事

    DataClasses1DataContext db = new DataClasses1DataContext();
    var returnall = from p in db.Orders
                    select p.ShipName;

Answer 1

var returnall = from p in db.Orders
                orderby p.ShipName
                select p.ShipName;

可以在MSDN samples page上找到各种LINQ函数的方便参考。

Answer 2

您可以使用OrderBy为单个属性订购多个属性ThenBy

 DataClasses1DataContext db = new DataClasses1DataContext();
 var returnall = db.OrderBy(r=> r.OrderDelivaryDate).
                    ThenBy(r => r. OrderName);

此查询将首先按OrderDelivaryDate排序，然后按OrderName
