這篇文章主要為大家詳細(xì)介紹了C#實(shí)現(xiàn)定時(shí)任務(wù)Task Scheduler的相關(guān)知識(shí),文中的示例代碼講解詳細(xì),感興趣的小伙伴可以跟隨小編一起學(xué)習(xí)一下

本文和大家分享一個(gè)自己寫的 Windows 定時(shí)任務(wù)計(jì)劃（Task Scheduler）動(dòng)態(tài)創(chuàng)建代碼，沒做太多封裝，留個(gè)實(shí)現(xiàn)筆記

首先封裝一個(gè)簡(jiǎn)單配置項(xiàng)的類

核心代碼

public class TaskSchedulerConfig
{
    /// <summary>
    /// 引用程序路徑
    /// </summary>
    public string ApplicationPath { get; set; }
    /// <summary>
    /// 引用程序參數(shù)
    /// </summary>
    //public string ApplicationParameter { get; set; }
    /// <summary>
    /// 任務(wù)名稱
    /// </summary>
    public string TaskName { get; set; }
    /// <summary>
    /// 任務(wù)說明
    /// </summary>
    public string TaskDescription { get; set; }
    /// <summary>
    /// 任務(wù)執(zhí)行周期 0 每日?qǐng)?zhí)行 1 每周執(zhí)行 2 每月執(zhí)行
    /// </summary>
    public int TaskExecutionCycle { get; set; }
    /// <summary>
    /// 開始執(zhí)行時(shí)間范圍 yyyy/MM/dd HH:mm:ss
    /// </summary>
    public DateTime StartBoundary { get; set; }
    /// <summary>
    /// 每月的第幾號(hào)執(zhí)行
    /// </summary>
    public int DaysOfMonth { get; set; }
    /// <summary>
    /// 每周的周幾執(zhí)行
    /// </summary>
    public int DaysOfWeek { get; set; }


}

兩個(gè)范圍判定的方法

 /// <summary>
          /// 根據(jù)數(shù)字1-7來設(shè)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("無(wú)效的數(shù)字。請(qǐng)?zhí)峁?到7之間的數(shù)字。");
             }
         }
         /// <summary>
         /// 限定每月只能在1-28號(hào)之間執(zhí)行任務(wù)
         /// </summary>
         /// <param name="num"></param>
         /// <returns></returns>
         static int GetDaysOfMonth(int num)
         {
             if (num < 1 || num > 28)
             {
                 throw new ArgumentException("無(wú)效的數(shù)字。請(qǐng)?zhí)峁?到28之間的數(shù)字。");
             }
             return num;
         }
