Question

在@Amy和@MongZhu的帮助下，我已经能够解决我的大多数原始问题，但现在我遇到了一个问题，其中JobName数组为我提供了错误数组不包含OrderBy的定义，我认为它可能与放置数组的位置有关。

Answer 1

OrderBy是一个linq方法，您需要命名空间System.Linq

OrderBy - 根据键按升序对序列元素进行排序。
OrderByDescending - 根据键按降序排序序列的元素。

使用OrderBy的示例

using System;
using System.Linq;

namespace Test.SO47928637
{
    public class Jobs
    {
        public string JobName { get; set; }
        public int JobTime { get; set; }

        public override string ToString()
        {
            return "Job" + JobName + ": " + JobTime;
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("This program simulates SJN of five jobs");

            Console.WriteLine("Please enter the time in ms for the following jobs");
            //Reading in the Times for jobs 

            Console.WriteLine("Job A Time (ms): ");
            string TimeOneText = Console.ReadLine();
            int JobTimeOne = int.Parse(TimeOneText);
            Jobs jobsA = new Jobs { JobName = "A", JobTime = JobTimeOne };
            Console.WriteLine(jobsA);//Error checking 

            Console.WriteLine("Job B Time (ms): ");
            string TimeTwoText = Console.ReadLine();
            int JobTimeTwo = int.Parse(TimeTwoText);
            Jobs jobsB = new Jobs { JobName = "B", JobTime = JobTimeTwo };
            Console.WriteLine(jobsB);//Error checking

            Console.WriteLine("Job C Time (ms): ");
            string TimeThreeText = Console.ReadLine();
            int JobTimeThree = int.Parse(TimeThreeText);
            Jobs jobsC = new Jobs { JobName = "C", JobTime = JobTimeThree };
            Console.WriteLine(jobsC);//Error checking

            Console.WriteLine("Job D Time (ms): ");
            string TimeFourText = Console.ReadLine();
            int JobTimeFour = int.Parse(TimeFourText);
            Jobs jobsD = new Jobs { JobName = "D", JobTime = JobTimeFour };
            Console.WriteLine(jobsD);//Error checking

            Console.WriteLine("Job E Time (ms): ");
            string TimeFiveText = Console.ReadLine();
            int JobTimeFive = int.Parse(TimeFiveText);
            Jobs jobsE = new Jobs { JobName = "E", JobTime = JobTimeFive };
            Console.WriteLine(jobsE);//Error checking

            Console.ReadLine();
            //Create an array for Job titles
            Jobs[] JobName = { jobsA, jobsB, jobsC, jobsD, jobsE };

            var items = JobName.OrderBy(o => o.JobName).ToList();
            Console.WriteLine("Order by JobName");
            foreach (var item in items)
            {
                Console.WriteLine(item.ToString());
            }

            items = JobName.OrderBy(o => o.JobTime).ToList();
            Console.WriteLine("Order by JobTime");
            foreach (var item in items)
            {
                Console.WriteLine(item.ToString());
            }

            items = JobName.OrderByDescending(o => o.JobTime).ToList();
            Console.WriteLine("Order by descending JobTime");
            foreach (var item in items)
            {
                Console.WriteLine(item.ToString());
            }

            Console.ReadLine();
        }
    }
}
