请记住，Web应用程序是无状态的. webform_1将无法记住以前的值.您需要保存值.有许多保存值的方法.您要保存的状态的性质和类型对于使用哪种机制会有一定的影响.这里没有一些特别的顺序.

1. 会话状态 [应用程序 [缓存 [ Cookie [

Remeber that web application are stateless. webform_1 won''t be able to remember previous values. You need to save the values. There are many ways of saving the values. The nature and type of the state you want to save will have some infunce as to which mechanism to use. In no particualr order here are some of them.

1. Session State [^]
2. Application[^]
3. Cache[^]
4. Database
5. Cookie[^]

If it is simple you may use session variable

//Set value
Session["MyValue"] =  value;

//Get value
value = Session["MyValue"];

您可以将其作为查询字符串 [

You can pass it to your page as Query String[^] as well.
