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 }
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 }
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 }"; 21 22 Console.WriteLine($"参数错误,正确示例：{demo}"); 23 return; 24 } 25 26 27 try 28 { 29 using (TaskService taskService = new TaskService()) 30 { 31 // 创建一个新任务 32 TaskDefinition taskDefinition = taskService.NewTask(); 33 taskDefinition.Principal.UserId = "SYSTEM"; // 设置为SYSTEM以在系统级别运行 34 // 设置任务的基本信息 35 taskDefinition.RegistrationInfo.Description = taskSchedulerConfig.TaskDescription; 36 37 switch (taskSchedulerConfig.TaskExecutionCycle) 38 { 39 case 0: 40 DailyTrigger dailyTrigger = new DailyTrigger(); 41 dailyTrigger.StartBoundary = taskSchedulerConfig.StartBoundary; 42 dailyTrigger.DaysInterval = 1; // 每天执行 43 taskDefinition.Triggers.Add(dailyTrigger); 44 break; 45 case 1: 46 WeeklyTrigger weeklyTrigger = new WeeklyTrigger(); 47 weeklyTrigger.StartBoundary = taskSchedulerConfig.StartBoundary; 48 weeklyTrigger.DaysOfWeek = GetDaysOfTheWeek(taskSchedulerConfig.DaysOfWeek); 49 weeklyTrigger.WeeksInterval = 1; // 每隔1周执行 50 taskDefinition.Triggers.Add(weeklyTrigger); 51 break; 52 case 2: 53 MonthlyTrigger monthlyTrigger = new MonthlyTrigger(); 54 monthlyTrigger.StartBoundary = taskSchedulerConfig.StartBoundary; 55 monthlyTrigger.DaysOfMonth = new[] { GetDaysOfMonth(taskSchedulerConfig.DaysOfMonth) }; 56 monthlyTrigger.MonthsOfYear = MonthsOfTheYear.AllMonths; // 每个月执行 57 taskDefinition.Triggers.Add(monthlyTrigger); 58 break; 59 default: 60 Console.WriteLine("任务执行周期参数错误！正确示例：0 每日执行 1 每周执行 2 每月执行"); 61 break; 62 } 63 64 65 66 // 设置要执行的程序路径 67 taskDefinition.Actions.Add(new ExecAction(taskSchedulerConfig.ApplicationPath, null, null)); 68 69 // 将任务注册到 Windows 任务计划程序 70 taskService.RootFolder.RegisterTaskDefinition(taskSchedulerConfig.TaskName, taskDefinition); 71 Console.WriteLine("任务计划创建成功！"); 72 } 73 } 74 catch (Exception ex) 75 { 76 Console.WriteLine($"创建{taskSchedulerConfig.TaskName} 任务错误，错误原因是：{ex.Message}"); 77 } 78 79 80 }
// 设置要执行的程序路径
//这里要补充一下，要设置一下起始于这个选项，起始于的目的是指定你执行文件的根目录，如果你没有指定程序就会寻址到C:\Windows\system32这个目录
taskDefinition.Actions.Add(new ExecAction(Path.GetFileName(taskSchedulerConfig.ApplicationPath), arguments, Path.GetDirectoryName(taskSchedulerConfig.ApplicationPath)));
