从aspx页面访问静态变量

Question

 public partial class Page1 :System.Web.UI.Page
 {
      public static LGDP.LDGPSession var1 = null;

      private void Login(this, EventArgs e)
      {
           var1 = new LGDPSession(this, data, data);
      }

      public bool IsLoggedIn()
      {
           bool login = false;

           if (var1 != null)
           {
                login = true;
           }

           return var1;
      }
 }

How do I access the Page1 static var1 or function IsLoggedIn() from Page2.apsx ?

 public partial class Page2 :System.Web.UI.Page
 {
      Page1.(nothing shows up here)
 }

ANSWER ----- created separate class and accessed public var in pageload / postback

private static bool _login = false;

public static void SetLoggedIn(object lgdps)
{
    if (lgdps == null)
    {
        _login = false;
    }

    if (lgdps != null)
    {
        _login = true;
    }
}

public static bool IsLogin
{
    get { return _login; }
}

Answer 1

Your function IsLoggedIn in Page1 doesn't compile. It has to return something:

public bool IsLoggedIn()
{
  bool login = false;

  if (var1 != null)
  {
    login = true;
  }

  return login;
}

Or simply:

public bool IsLoggedIn()
{
  return var1 != null;
}

Once the page compiles, its members should show up in the intellisense.

Answer 2

It's better to create a base class with your functions in it:

public class BasePage : Page
{    
      public bool IsLoggedIn()
      {
           bool login = false;

           if (var1 != null)
           {
                login = true;
           }
      }

}

And then you can access IsLoggedIn from you pages when you inherit from BasePage

public partial class Page1 : BasePage
{
}

public partial class Page2 : BasePage
{
  protected void Page_Load(object sender, EventArgs e)
  {
        if(IsLoggedIn())
        {
        }
  }   
}
