C#操作计划任务
昨天有一个任务,就是要下载相关文件,然后保存在相关路径下,这个没什么难度,所以就略过不谈,主要谈谈定时下载,即每天某个固定时间执行下载,这个功能我是用C#代码来操作windows自带的任务计划来实现的,所以我简单的写了一个任务计划操作类,以下是代码主体部分,基本上可实现我需要的功能,当然,因为时间仓促,还不是很完善,我会尽量抽时间完善这个公共类,以便以后操作的时候,可以直接使用,废话说完,开始进入正题:
1,首先下载TaskScheduler.dll,然后将其添加到引用中。
2,然后下面是TaskSchedulerHandler.cs的代码,也就是满足我的需要的操作类
- /// <summary>
- /// @Date:12/10/2012
- /// @Author:Andy
- /// @Desciption:class of add,delete and select Task Scheduler
- /// </summary>
- public class TaskSchedulerHandler
- {
- public string hour;//task hour
- public string minute;//task minute
- public string interval;//task interval
- public string taskName;//Name of Task
- public string userName;//user to authorize the task
- public string userPwd;//password of user
- public TaskSchedulerHandler()
- {
- InitVariables();
- }
- /// <summary>
- /// Add Task to TaskScheduler
- /// </summary>
- public void AddTask()
- {
- if (!SelTask())
- {
- ScheduledTasks st = new ScheduledTasks();
- Task autoDownload = st.CreateTask(taskName);
- DailyTrigger dayTrigger = new DailyTrigger(Convert.ToInt16(hour), Convert.ToInt16(minute), Convert.ToInt16(interval));//get default config from app.config
- autoDownload.Triggers.Add(dayTrigger);
- //autoDownload.SetAccountInformation(userName, userPwd);//to authorize the console ro run
- autoDownload.ApplicationName = Assembly.GetExecutingAssembly().Location;
- //you can also modify the values in app.config
- //and publish it, then you can add the application name here
- //autoDownload.ApplicationName = "";
- autoDownload.Save();
- autoDownload.Close();
- }
- //else
- //{
- // DelTask(taskName);
- // AddTask();
- //}
- }
- /// <summary>
- /// Select Task from TaskScheduler
- /// </summary>
- /// <param name="taskName"></param>
- /// <returns></returns>
- public bool SelTask()
- {
- bool flag = false;
- ScheduledTasks st = new ScheduledTasks();
- string[] taskNameStr = st.GetTaskNames();
- foreach (string item in taskNameStr)
- {
- if (taskName == item.Split('.')[0])
- {
- flag = true;
- break;
- }
- }
- return flag;
- }
- /// <summary>
- /// Delete Task
- /// </summary>
- /// <param name="taskName"></param>
- public void DelTask(string taskName)
- {
- if (taskName != "" && taskName != null)
- {
- ScheduledTasks st = new ScheduledTasks();
- st.DeleteTask(taskName);
- }
- }
- /// <summary>
- /// Set Default Value for Variables
- /// </summary>
- public void InitVariables()
- {
- hour = ConfigurationManager.AppSettings["taskHour"];
- minute = ConfigurationManager.AppSettings["taskMinute"];
- interval = ConfigurationManager.AppSettings["interval"];
- taskName = ConfigurationManager.AppSettings["taskName"];
- userName = ConfigurationManager.AppSettings["taskUser"];
- userPwd = ConfigurationManager.AppSettings["taskPwd"];
- }
- }
这样,一个简单的任务计划操作类就完成了,简单说下,因为目前我的很多的值都需要存储在app.config中,以便日后修改或进行配置,所以我的变量大多是直接读取app.config中的值来实现赋值的,这也是下一步我打算完善的,希望把这个作为一个公共类,可以让其他人直接使用。
