LINQ到SQL連接

Question

我在我的LINQ中使用以下表達式來連接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(); 

它給這個錯誤：

錯誤1無法分配方法組到一個隱式類型的局部變量

如何解決呢？

Answer 1

你忘了實際調用的計數方法，加括號：

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