linq到sql连接

Question

我在linq to sql连接中使用了以下表达式。

       int before = db.Employees.Count();

        var after = (from c in db.Employees
                     where c.emp_city == "pune"
                     select c).Count;


        Console.WriteLine("# of Customers= {0}, In pune= {1}", before, after);


        Console.ReadLine();

它给出了这个错误：

错误1无法将方法组分配给隐式类型的局部变量

如何解决？

Answer 1

你忘了实际调用Count方法，添加括号：

 var after = (from c in db.Employees
                 where c.emp_city == "pune"
                 select c).Count();
