Hi,
I am working on a web application in vb.net 2005.
default.aspx is a main page and mailutil.vb is referred from Application code folder in that web application.

I want to pass ID from aspx page to mailutil.vb page in Application code folder. I can''t use query string,session,cookies in that page.

Is there any method ?

I want to pass a ID to that function from a .aspx page to mailutil.vb


thanks in advance..

regards,

推荐答案

首先可以使用Session，Request，Response，Server等.
如果我理解正确，mailutil.vb是一个类.

1.添加到此类:

First of all you can use Session, Request, Response, Server, etc.
If I understood you correctly mailutil.vb is a class.

1. Add to this class:

using System.Web;

2.在要检索的方法中，说Session ["myPassedID"]获取会话对象:

2. In the method where you want to retrieve say Session["myPassedID"] get the session object:

System.Web.SessionState.HttpSessionState session = HttpContext.Current.Session;

string myID = session["myPassedID"];

祝您好运

Good luck

您能否仅将它作为default.aspx.vb中的一个参数传递:

can you not just pass it as a parameter from your default.aspx.vb:

Dim someParam as Int
someParam = 123

mailutil.SomeMethod(someParam)

还是我错过了什么?

or am I missing something?

我无法完全理解您的问题.
只需在您的mailutil.vb的类中保留一个公共静态变量

语法:
公用共享的dim id为String

这样一来，您就可以在不需任何地方创建实例的情况下对其进行读/写操作
(mailutil.id)

I could not understand y''r question thoroughly.
Just keep a public static variable in your mailutil.vb''s class

Syntax:
Public Shared dim id as String

Then you''ll be able to read/write to it without creating an instance as you wish from anywhere
(mailutil.id)
