分享一个我自己写的 Windows 定时任务计划（Task Scheduler） 动态创建代码，没做太多封装，留个实现笔记
首先封装一个简单配置项的类
1 public class TaskSchedulerConfig
2 {
3 /// <summary>
4 /// 引用程序路径
5 /// </summary>
6 public string ApplicationPath { get; set; }
7 /// <summary>
8 /// 引用程序参数
9 /// </summary>
10 //public string ApplicationParameter { get; set; }
11 /// <summary>
12 /// 任务名称
13 /// </summary>
14 public string TaskName { get; set; }
15 /// <summary>
16 /// 任务说明
17 /// </summary>
18 public string TaskDescription { get; set; }
19 /// <summary>
20 /// 任务执行周期 0 每日执行 1 每周执行 2 每月执行
21 /// </summary>
22 public int TaskExecutionCycle { get; set; }
23 /// <summary>
24 /// 开始执行时间范围 yyyy/MM/dd HH:mm:ss
25 /// </summary>
26 public DateTime StartBoundary { get; set; }
27 /// <summary>
28 /// 每月的第几号执行
29 /// </summary>
30 public int DaysOfMonth { get; set; }
31 /// <summary>
32 /// 每周的周几执行
33 /// </summary>
34 public int DaysOfWeek { get; set; }
35
36
37 }View Code
1 /// <summary>
2 /// 根据数字1-7来设置周一 - 周日
3 /// </summary>
4 /// <param name="num"></param>
5 /// <returns></returns>
6 static DaysOfTheWeek GetDaysOfTheWeek(int num)
7 {
8 switch (num)
9 {
10 case 1:
11 return DaysOfTheWeek.Monday;
12 case 2:
13 return DaysOfTheWeek.Tuesday;
14 case 3:
15 return DaysOfTheWeek.Wednesday;
16 case 4:
17 return DaysOfTheWeek.Thursday;
18 case 5:
19 return DaysOfTheWeek.Friday;
20 case 6:
21 return DaysOfTheWeek.Saturday;
22 case 7:
23 return DaysOfTheWeek.Sunday;
24 default:
25 throw new ArgumentException("无效的数字。请提供1到7之间的数字。");
26 }
27 }
28 /// <summary>
29 /// 限定每月只能在1-28号之间执行任务
30 /// </summary>
31 /// <param name="num"></param>
32 /// <returns></returns>
33 static int GetDaysOfMonth(int num)
34 {
35 if (num < 1 || num > 28)
36 {
37 throw new ArgumentException("无效的数字。请提供1到28之间的数字。");
38 }
39 return num;
40 }两个范围判定的方法
1 static void Main(string[] args)
2 {
3
4 TaskSchedulerConfig taskSchedulerConfig;
5 try
6 {
7 var taskSchedulerConfigJson = args[0];
8 taskSchedulerConfig = JsonConvert.DeserializeObject<TaskSchedulerConfig>(taskSchedulerConfigJson);
9 }
10 catch
11 {
12 string demo = @"{
13 ""ApplicationPath"": ""C:\\YourApplication\\YourExecutable.exe"",
14 ""TaskName"": ""DailyTask"",
15 ""TaskDescription"": ""This is a daily task"",
16 ""TaskExecutionCycle"": 0,
17 ""StartBoundary"": ""2024/02/28 08:00:00"",
18 ""DaysOfMonth"": 28,
19 ""DaysOfWeek"": 3
20 }";

22 Console.WriteLine($"参数错误,正确示例：{demo}");
23 return;
24 }

27 try
28 {
29 using (TaskService taskService = new TaskService())
30 {
31 // 创建一个新任务
32 TaskDefinition taskDefinition = taskService.NewTask();
33 taskDefinition.Principal.UserId = "SYSTEM"; // 设置为SYSTEM以在系统级别运行
34 // 设置任务的基本信息
35 taskDefinition.RegistrationInfo.Description = taskSchedulerConfig.TaskDescription;
36
37 switch (taskSchedulerConfig.TaskExecutionCycle)
38 {
39 case 0:
40 DailyTrigger dailyTrigger = new DailyTrigger();
41 dailyTrigger.StartBoundary = taskSchedulerConfig.StartBoundary;
42 dailyTrigger.DaysInterval = 1; // 每天执行
43 taskDefinition.Triggers.Add(dailyTrigger);
44 break;
45 case 1:
46 WeeklyTrigger weeklyTrigger = new WeeklyTrigger();
47 weeklyTrigger.StartBoundary = taskSchedulerConfig.StartBoundary;
48 weeklyTrigger.DaysOfWeek = GetDaysOfTheWeek(taskSchedulerConfig.DaysOfWeek);
49 weeklyTrigger.WeeksInterval = 1; // 每隔1周执行
50 taskDefinition.Triggers.Add(weeklyTrigger);
51 break;
52 case 2:
53 MonthlyTrigger monthlyTrigger = new MonthlyTrigger();
54 monthlyTrigger.StartBoundary = taskSchedulerConfig.StartBoundary;
55 monthlyTrigger.DaysOfMonth = new[] { GetDaysOfMonth(taskSchedulerConfig.DaysOfMonth) };
56 monthlyTrigger.MonthsOfYear = MonthsOfTheYear.AllMonths; // 每个月执行
57 taskDefinition.Triggers.Add(monthlyTrigger);
58 break;
59 default:
60 Console.WriteLine("任务执行周期参数错误！正确示例：0 每日执行 1 每周执行 2 每月执行");
61 break;
62 }
63
64
65
66 // 设置要执行的程序路径
67 taskDefinition.Actions.Add(new ExecAction(taskSchedulerConfig.ApplicationPath, null, null));
68
69 // 将任务注册到 Windows 任务计划程序
70 taskService.RootFolder.RegisterTaskDefinition(taskSchedulerConfig.TaskName, taskDefinition);
71 Console.WriteLine("任务计划创建成功！");
72 }
73 }
74 catch (Exception ex)
75 {
76 Console.WriteLine($"创建{taskSchedulerConfig.TaskName} 任务错误，错误原因是：{ex.Message}");
77 }
