Cannot get session in webmethod in asp.net

Question

I just find that the problem is not related to the webmethod.

It is caused by another problem.

I set the Session["PhotoId"] in a normal aspx. But I can't retrieve value in the webMethod of the aspx page.

[WebMethod(EnableSession=true)]
    public static string Submit(string data1, ...)
    {
        string test = HttpContext.Current.Session["PhotoId"]; // test is null
    }

What should I do?

check if the sessionid is same.

As I see, everything should be fine here.

As far as HttpContext.Current.Session is not null, session state is supported here. Please ensure, that you set Session["PhotoId"].

You can test whether it is the same session by examining

 HttpContext.Current.Session.SessionID

in both normal ASPX and WebMethod.

How or why SessionId could be different?

You should use ToString() method to use session as a string.

[WebMethod(EnableSession=true)]
public static string Submit(string data1, ...)
{
    string test = HttpContext.Current.Session["PhotoId"].ToString(); 
}
