Asp.Net程序根目录下文件夹操作导致Session失效的解决方案

1、配置web.config

<system.web>
    <sessionState mode="StateServer" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data
    source=127.0.0.1;Trusted_Connection=yes" cookieless="false" timeout="40"/>
</system.web>

2、在Global.asax中添加启动启动ASP.NET 状态服务代码

void Application_Start(object sender, EventArgs e)
    {
        // 在应用程序启动时运行的代码
        try
        {
            //启动ASP.NET 状态服务
            string g_serviceName = "aspnet_state";

            System.ServiceProcess.ServiceController[] serviceControllers =
                System.ServiceProcess.ServiceController.GetServices();

            foreach (System.ServiceProcess.ServiceController service in serviceControllers)
            {
                if (service.ServiceName == g_serviceName)
                {
                    if (service != null && service.Status != System.ServiceProcess.ServiceControllerStatus.Running)
                    {
                        service.Start();
　　　　　　　　　　　　　　 SimpleLogHelper.WriteError(g_serviceName + "服务已开启");
                    }
                    else
                    {
                        if (service == null)
                        {
                            SimpleLogHelper.WriteError(g_serviceName + "服务未安装");
                        }
                        else
                        {
                            SimpleLogHelper.WriteError(g_serviceName + "服务正在运行...");
                        }
                    }
                    break;
                }
            }
        }
        catch (Exception ex)
        {
            SimpleLogHelper.WriteError(ex.ToString());
        }
    }
