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
public class TaskSchedulerConfig
{
/// <summary>
/// 引用程序路径
/// </summary>
public string ApplicationPath { get; set; }
/// <summary>
/// 引用程序参数
/// </summary>
//public string ApplicationParameter { get; set; }
/// <summary>
/// 任务名称
/// </summary>
public string TaskName { get; set; }
/// <summary>
/// 任务说明
/// </summary>
public string TaskDescription { get; set; }
/// <summary>
/// 任务执行周期 0 每日执行 1 每周执行 2 每月执行
/// </summary>
public int TaskExecutionCycle { get; set; }
/// <summary>
/// 开始执行时间范围 yyyy/MM/dd HH:mm:ss
/// </summary>
public DateTime StartBoundary { get; set; }
/// <summary>
/// 每月的第几号执行
/// </summary>
public int DaysOfMonth { get; set; }
/// <summary>
/// 每周的周几执行
/// </summary>
public int DaysOfWeek { get; set; }
}
/// <summary>
/// 根据数字1-7来设置周一 - 周日
/// </summary>
/// <param name="num"></param>
/// <returns></returns>
static DaysOfTheWeek GetDaysOfTheWeek(int num)
{
switch (num)
{
case 1:
return DaysOfTheWeek.Monday;
case 2:
return DaysOfTheWeek.Tuesday;
case 3:
return DaysOfTheWeek.Wednesday;
case 4:
return DaysOfTheWeek.Thursday;
case 5:
return DaysOfTheWeek.Friday;
case 6:
return DaysOfTheWeek.Saturday;
case 7:
return DaysOfTheWeek.Sunday;
default:
throw new ArgumentException("无效的数字。请提供1到7之间的数字。");
}
}
/// <summary>
/// 限定每月只能在1-28号之间执行任务
/// </summary>
/// <param name="num"></param>
/// <returns></returns>
static int GetDaysOfMonth(int num)
{
if (num < 1 || num > 28)
{
throw new ArgumentException("无效的数字。请提供1到28之间的数字。");
}
return num;
}
两个日期范围判定的方法
static void Main(string[] args)
{
TaskSchedulerConfig taskSchedulerConfig;
try
{
var taskSchedulerConfigJson = args[0];
taskSchedulerConfig = JsonConvert.DeserializeObject<TaskSchedulerConfig>(taskSchedulerConfigJson);
}
catch

""StartBoundary"": ""2024/02/28 08:00:00"",
""DaysOfMonth"": 28,
""DaysOfWeek"": 3
}";
Console.WriteLine($"参数错误,正确示例：{demo}");
return;
}
try
{
using (TaskService taskService = new TaskService())
{
// 创建一个新任务
TaskDefinition taskDefinition = taskService.NewTask();
taskDefinition.Principal.UserId = "SYSTEM"; // 设置为SYSTEM以在系统级别运行
// 设置任务的基本信息
taskDefinition.RegistrationInfo.Description = taskSchedulerConfig.TaskDescription;
switch (taskSchedulerConfig.TaskExecutionCycle)
{
case 0:
DailyTrigger dailyTrigger = new DailyTrigger();
dailyTrigger.StartBoundary = taskSchedulerConfig.StartBoundary;
dailyTrigger.DaysInterval = 1; // 每天执行
taskDefinition.Triggers.Add(dailyTrigger);
break;
case 1:
WeeklyTrigger weeklyTrigger = new WeeklyTrigger();
weeklyTrigger.StartBoundary = taskSchedulerConfig.StartBoundary;
weeklyTrigger.DaysOfWeek = GetDaysOfTheWeek(taskSchedulerConfig.DaysOfWeek);
weeklyTrigger.WeeksInterval = 1; // 每隔1周执行
taskDefinition.Triggers.Add(weeklyTrigger);
break;
case 2:
MonthlyTrigger monthlyTrigger = new MonthlyTrigger();
monthlyTrigger.StartBoundary = taskSchedulerConfig.StartBoundary;
monthlyTrigger.DaysOfMonth = new[] { GetDaysOfMonth(taskSchedulerConfig.DaysOfMonth) };
monthlyTrigger.MonthsOfYear = MonthsOfTheYear.AllMonths; // 每个月执行
taskDefinition.Triggers.Add(monthlyTrigger);
break;
default:
Console.WriteLine("任务执行周期参数错误！正确示例：0 每日执行 1 每周执行 2 每月执行");
break;
}
// 设置要执行的程序路径
taskDefinition.Actions.Add(new ExecAction(taskSchedulerConfig.ApplicationPath, null, null));
// 将任务注册到 Windows 任务计划程序
taskService.RootFolder.RegisterTaskDefinition(taskSchedulerConfig.TaskName, taskDefinition);
Console.WriteLine("任务计划创建成功！");
}
}
catch (Exception ex)
{
Console.WriteLine($"创建{taskSchedulerConfig.TaskName} 任务错误，错误原因是：{ex.Message}");
