推荐答案

您有很多选择可以做到这一点.


为了获得总体思路，请在msdn中查看此页面；

ASP.net状态管理概述 [ ASP.net会话状态概述 [状态管理 [ ^ ]

会话概述 [

You have numerous of options to do that.


In order to get the general idea have a look at this page in msdn;

ASP.net State Management Overview[^]

ASP.net session state overview[^]

State management[^]

Session overview[^]

A basic code example is;
This is an example of Session;

object sessionObject = Session["someObject"];

if (sessionObject != null) 
{ 
   myLabel.Text = sessionObject.ToString(); 
}

或者，如果您不想使用状态，则可以使用QueryString在页面之间进行传递(减少状态管理开销的非常常用的技术)

使用QueryString在页面之间传递变量 [

Or if you don''t want to use state, you can pass from page to page using QueryString (very common technique to reduce state management overhead)

Passing variables between pages using QueryString[^]

主要是会话和查询字符串用于传输数据.

Mainly Session and Query String is used to transfer data.

Response.Redirect("Abc.aspx?ID=2");

在Abc.aspx中

And in Abc.aspx

String ID = Request.QueryString["ID"];

还有

And

Session["ID"]=ID;

在下一页

in next Page

String ID = Session["ID"].ToString();
