停止服务后杀死进程

Question

我正在尝试在我停止服务后终止一个服务进程，该服务正在下降非常慢 - 类似于7秒，程序通过进程ID终止进程，但是当我遇到它时它会获得ArgumentException试图用命令行做它仍然告诉我进程正在运行虽然我需要用/ F（强制）杀死它 我错过了什么？

    public void KillService(uint processID)
    {
     try
        {                
            process = Process.GetProcessById((int)processID);
            if (process != null)
            {
                process.Kill(); 

            }                                                                
        }
        catch (ArgumentException)
        {
            // Thrown if the process specified by processID
            // is no longer running.               
        }
        catch (Win32Exception)
        {
            // Thrown if process is already terminating,
            // the process is a Win16 exe or the process
            // could not be terminated.

        }
        catch (InvalidOperationException)
        {
            // Thrown if the process has already terminated.

        }
   }
