LINQ到SQL连接

Question

我在我的LINQ中使用以下表达式来连接sql。

 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(); 

它给这个错误：

错误1无法分配方法组到一个隐式类型的局部变量

如何解决呢？

Answer 1

你忘了实际调用的计数方法，加括号：

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