System.Diagnostics.Process启动傲游浏览器项目实例 - xionglee

      需求：在一个winform项目中，每次执行数据库查询时，如发现通过vpn页面访问远程数据库失败，则希望重新启动傲游浏览器，打开指定的vpn页面。

      代码：

 

Code
if(!dbs_Forecast.dbConnectionValid_get)    //立即判断该值
                                {
                                    //一旦数据库连接中断，则判断任务管理器的进程列表之中，是否存在Maxthon.exe进程，如果进程存在，
                                    //则关闭Maxthon进程，再重新启动该进程。
                                    //上述操作只会执行一次，如果再次打开vpn之后，仍然无法连接79数据库，则后续网格的数据获取操作将不再执行。
                                    Process[] curProcessArray = System.Diagnostics.Process.GetProcessesByName("Maxthon");
                                    if(curProcessArray.Length>0)    //返回的进程数组应该只有一个元素
                                    {
                                        Process MaxthonProcess = curProcessArray[0];
                                        try
                                        {
                                            //bool closeValid = MaxthonProcess.CloseMainWindow();
                                            //if(!closeValid)
                                                MaxthonProcess.Kill();
                                            string maxthonConfigPath = System.Configuration.ConfigurationSettings.AppSettings["maxthonExplorerLoadPath"];
                                            string maxthonPath = @maxthonConfigPath;
                                            ProcessStartInfo psi = new ProcessStartInfo();
                                            psi.FileName = maxthonPath;
                                            psi.Arguments = @"sqvpn.hydroinfo.gov.cn";
                                            System.Diagnostics.Process.Start(psi);
                                            
                                            //再次进行该网格的数据查询
                                            dbs_Forecast.dbConnectionValid_get = true;    //需要再次将其设置其为初始状态
                                            gridDataTbl = dbs_Forecast.getGridDataRecrds(gridIdArray[i],queryTime);    //单点查询模式
                                            //如果经过再次打开vpn窗口之后，仍然无法连接，则后续网格的数据获取将不再执行
                                            if(!dbs_Forecast.dbConnectionValid_get)    //再次立即判断该值
                                            {
                                                //一旦发生网络中断，则在这里要记录此时的单点主查询时间
                                                lastQueryTime_ConnectionException = queryTime;
                                                setStatus_Forecast("read","读取"+queryTime.ToString()+"时刻网格"+"("+gridIdArray[i]+")"+"的数值预报记录时，发生了数据库连接中断！",progressValue_read_Forecast.ToString()+"%","("+readGridCounter.ToString()+"/"+totalGridNums_Forecast+")");
                                            }
                                        }
                                        catch//(System.ComponentModel.Win32Exception ex)
                                        {
                                            //MessageBox.Show(ex.Message);
                                        }
                                    }
                                    else    //当前任务管理器进程列表中未存在Maxthon进程，则启动Maxthon进程，并打开vpn页面
                                    {
