 https://msdn.microsoft.com/en-us/library/windows/desktop/ms681381(v=vs.85).aspx 错误代码

需求：很多时候我们需要后台运行几个Console来不停的计算数据，那么部署到客户服务器后，如果出现突发异常，程序挂掉了，那。。。？  
 解决方案：封装了一个对后台运行程序不停监测的功能，如果发现程序有异常，但是进程还在，这个时候就Kill掉这个进程，重启后台计算程序，这里的计算程序均为"控制台运行程序"。
异常中可以看到，Kill()进程的时候出现"拒绝访问"，在网上搜了下，
解决方案大致就这几种： 在config里增加identity
<system.web>　　
<identity impersonate="true" userName="Administrator" password="123456" />
</system.web>　
检测程序用"管理员身份运行"对监测的程序目录分配权限结果是这几种方式都没能解决此问题。  
 我查看了Kill()方法的注释：  
 //        // 摘要:        
//     立即停止关联的进程。     
  //        // 异常:      
  //   System.ComponentModel.Win32Exception:     
  //     未能终止关联的进程。 - 或 - 正在终止该进程。 - 或 - 关联的进程是一个 Win16 可执行文件。     
  //        //   System.NotSupportedException:       
//     您正尝试为远程计算机上运行的进程调用 System.Diagnostics.Process.Kill()。 该方法仅对在本地计算机上运行的进程可用。        //        //   System.InvalidOperationException:       
//     该进程已经退出。 - 或 - 没有与此 System.Diagnostics.Process 对象关联的进程。       
public void Kill(); 
发现是一个Win32Exception的异常，随后我又查阅了ms的官方文档，果然有发现： 
大概意思就是说如果这个监测程序是Console，這样写是没问题的，可以正常结束掉进程。但这里因为需要在界面上展现出一些监测数据，这里我用的是WPF，也就是文档里说的图像界面程序。
 MS的原话是这样的：如果调用 Kill，则可能丢失进程编辑的数据或分配给进程的资源。
Kill 导致进程不正常终止，因而只应在必要时使用。CloseMainWindow 使进程能够有序终止并关闭所有窗口，所以对于有界面的应用程序，使用它更好。如果 CloseMainWindow 失败，则可以使用 Kill终止进程。Kill 是终止没有图形化界面的进程的唯一方法。 将Kill方法()改成了CloseMainWindow()即可正常杀掉进程。 
调用PDA中的接口调试，程序直接死了，不能结束进程，要重启wince系统。复制到PDA中程序可以正常调用扫码接口，未解之谜。。。此代码一部分用处在于此 ，尴尬。
