List <T> .Find(Predicates/Lambda)

Question

有人能告诉我以下3个查找选项之间的差异/优势:

        List<Employee> Employees = new List<Employee>();

        Employee tmp = new Employee();

        tmp.FirstName = "Randy";
        tmp.LastName = "Jones";
        Employees.Add(tmp);

        tmp.FirstName = "David";
        tmp.LastName = "Smith";
        Employees.Add(tmp);

        tmp.FirstName = "Michele";
        tmp.LastName = "Morris";
        Employees.Add(tmp);


        // Find option 1
        Employee eFound1= Employees.Find((Employee emp1) => {return emp1.LastName == "Jones";});

        // Find option 2
        Employee eFound2 = Employees.Find(emp2 => emp2.LastName == "Smith");

        // Find option 3
        Employee eFound3 = Employees.Find(
        delegate(Employee emp3)
        {
                return emp3.LastName == "Morris";
        }
        );

我一直在阅读有关lambdas和谓词的内容(我怀疑它与答案有某种联系),但我不能把它们放在一起.任何启示将不胜感激!

谢谢大卫

Answer 1

第一个是语句lambda,第二个是lambda表达式,第三个是匿名方法.

它们在功能上都是等价的.
