Linq to sql linq到sql连接
我在linq到sql连接中使用了以下表达式Linq to sql linq到sql连接,linq-to-sql,Linq To Sql,我在linq到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 pu
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();
它给出了以下错误:
错误1无法将方法组分配给隐式类型的局部变量
如何解决此问题?如果忘记实际调用Count方法,请添加括号:
var after = (from c in db.Employees
where c.emp_city == "pune"
select c).Count();
