基于winform的应用守护程序-支持服务与应用程序

• 在生产环境有时候部署的程序可能会因为意外情况被关闭

  • 程序异常
  • 系统异常
  • 人为误操作
  • 。。。

• 程序有需要永久开启的需求，这个时候需要有守护程序监测服务或者程序是否关闭，如果关闭了则再次启动。最近写了个简易的程序满足临时的需要。

• 

• 

• 通过配置文件设置对应需要守护的路径或名称。

• "CheckCircle": 5000,
  //服务名称列表
  "ServiceNameList": [],
  //应用程序列表
  "ApplicationNameList": [ "D:\\MyWorkSpace\\test.exe" ]

• 核心代码如下

• /// <summary>

  /// 检查服务并启动

  /// </summary>

  /// <returns></returns>

  private static async Task CheckServiceAndRunAsync()

  {

  Task.Run(async () =>

  {
