LINQ到SQL - 如何从查询

Question

结果进行排序我有一个LINQ查询我检索，虽然它的上下文我会怎么排序的输出，我已经试过sortby等，但都无济于事

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; 

各种LINQ功能的便捷参考可在MSDN samples page上找到。

Answer 2

order by

Answer 3

var ret = db.Orders.OrderBy(x => x.ShipName); 

Answer 4

可以使用OrderBy订购单一属性的多个属性使用ThenBy也

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

这个查询排序首先OrderDelivaryDate然后通过OrderName
