C#基础---Queue(队列)的应用

    public class Person
    {
        public string Name { get; set; }

        public string Address { get; set; }

        public int Age { get; set; }
    }

    public class ErrorMessage
    {
        public string ErrorCode { get; set; }

        public string ErrorInfo { get; set; }

        public override string ToString()
        {
            return string.Format("{0}:{1}", ErrorCode, ErrorInfo);
        }
    }

public class Program
    {
        public static void Main(string[] args)
        {
            Person person = new Person()
            {
                Name = "Frank Zhang",
                Address = "Chengdu",
                Age = 60
            };

            Queue<Func<Person, ErrorMessage>> myQueue = new Queue<Func<Person, ErrorMessage>>();
            ErrorMessage errorMessage = null;
            myQueue.Enqueue(CheckName);
            myQueue.Enqueue(CheckAge);

            var count = myQueue.Count;
            for (int index = 0; index < count; index++)
            {
                var checkMethod = myQueue.Dequeue();
                errorMessage = checkMethod(person);
                if (errorMessage != null)
                {
                    Console.WriteLine(errorMessage.ToString());
                    break;
                }
            }
        }

        public static ErrorMessage CheckName(Person person)
        {
            if (person != null && person.Name.EndsWith("Zhang"))
            {
                return new ErrorMessage() { ErrorCode = "Error_001", ErrorInfo = "我们不招姓张的" };
            }

            return null;
        }

        public static ErrorMessage CheckAge(Person person)
        {
            if (person != null && person.Age > 50)
            {
                return new ErrorMessage() { ErrorCode = "Error_002", ErrorInfo = "我们不招收老年人" };
            }

            return null;
        }
    }

    上面是在项目中看到的一些运用Check的小技巧。感觉还不错。分享出来。希望各位博友有啥好的想法可以分享一下。
