Entering the 'GetObjectsNonReenterant' state from the 'GetObjectsNonReenterant'

Question

DevExpress session

Answer 1

从错误提示看：你在InboundUpgrade_HandleUpgrade.ShowUpgradeInfo中调用了：session.GetObjectByKey
而这时候session中还在执行上一次的查询动作。你的Session实例是全局共享的？

Answer 2

是的啊 写在Global 中的 Application_Start方法中初始化的 大神告诉我 这个应该怎么解决啊， 我对xpo不熟悉啊

Answer 3

void Application_Start(object sender, EventArgs e)
    {
        string complain = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["Complain"].ConnectionString;
        string crm = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["CRM"].ConnectionString;
        Connection.InitializeSession(complain, crm);
}
 public static void InitializeSession(string strConnComplain, string strConnCRM)
    {
        Session_Complain = new Session();
        SqlConnection conn = new SqlConnection();
        conn.ConnectionString = strConnComplain;
        Session_Complain.Connection = conn;
        Session_Complain.AutoCreateOption = DevExpress.Xpo.DB.AutoCreateOption.SchemaOnly;
        Session_CRM = new Session();
        SqlConnection connCRM = new SqlConnection();
        connCRM.ConnectionString = strConnCRM;
        Session_CRM.Connection = connCRM;
        Session_CRM.AutoCreateOption = DevExpress.Xpo.DB.AutoCreateOption.None;
        Session_CRM.LockingOption = LockingOption.None;
        Session_CRM.OptimisticLockingReadBehavior = OptimisticLockingReadBehavior.Ignore;
        Session.DefaultSession.Connection = Session_Complain.Connection;
        Session.DefaultSession.LockingOption = LockingOption.None;
        Session.DefaultSession.OptimisticLockingReadBehavior = OptimisticLockingReadBehavior.Ignore;
        //SqlExcute.connectionString = strConnCRM;
        //SqlExcuteCampaign.connectionString = strConnComplain;
    }

Answer 4

不要用全局变量，每次用到再创建：
using(Session session = new Session()) {
  ... ...
}
