Question

我正在尝试在Windows服务应用程序中使用会话[“emailcc3”] ..但是它向我显示了在此上下文中不可用的错误会话....有没有其他方法可以做该??

这是我的代码：

 foreach (DataRow newRow in employee.Rows)
                {
                    num = num - 1;



                    if (num == 4)
                    {
                        Session["emailto"] = newRow["EMAILID"].ToString();
                    }
                    if (num == 3)
                    {
                        Session["emailcc1"] = newRow["EMAILID"].ToString();
                    }
                    if (num == 2)
                    {
                        Session["emailcc2"] = newRow["EMAILID"].ToString();
                    }
                    if (num == 1)
                    {
                        Session["emailcc3"] = newRow["EMAILID"].ToString();
                    }

                }

                string emailto = Session["emailto"].ToString();

                string emailcc1 = Session["emailcc1"].ToString();

                string emailcc2 = Session["emailcc2"].ToString();

                string emailcc3 = Session["emailcc3"].ToString();

如果我疯狂猜测，我认为你想要的只是：

string emailto = null;
string emailcc1 = null;
string emailcc2 = null;
string emailcc3 = null;

foreach (DataRow newRow in employee.Rows)
{
    num = num - 1;
    switch (num)
    {
       case 4:
          emailto = newRow["EMAILID"].ToString();
          break;
       case 3:
          emailcc1 = newRow["EMAILID"].ToString();
          break;
       case 2:
          emailcc2 = newRow["EMAILID"].ToString();
          break;
       case 1:
          emailcc3 = newRow["EMAILID"].ToString();
          break;
       default:
          //Do something here?
    }
}

我不确定您为什么要使用Session - 除非您使用它，因为它允许您动态声明变量，原样。

会话在Windows服务应用程序中不起作用？
