Question

SELECT fname || ' ' || lname AS name, fage
FROM people
ORDER BY name;

如何将上面的SQL代码转换为LINQ？

Answer 1

您可以使用let按匿名类型列进行排序。

var r = (from p in People
         let t = new {
            name = p.fname + " " + p.lname,
            fage = p.fage
         }
         orderby t.name
         select t);

Answer 2

如果人物对象包含fname，lname和fage，那么你可以这样做

people.Select(p=> new {name=p.fname + " " + p.lname,
                       fage=p.fage
                      }).OrderBy(a=>a.name).ToList();

Answer 3

试试这个。

(from p in People
select [Name] = p.fname & " " & f.lname, p.fage order by [Name]).ToList()
