当初是html 页面向aspx 页面传参数，说的是未将对象引用设置到对象的实例。 可是现在用aspx向aspx页面传递参数，还是说的是
未将对象引用设置到对象的实例。 郁闷啊，
html 向aspx传递参数没有正确是因为 name属性没有写正确
那aspx向aspx传递参数又是哪里不正确呢！！1.aspx

当然收不到值.
如果要传递可以用.
Response.Redirect("2.aspx?t1="+t1.Text);然后在2中string aa=Request.QueryString["t1"];
string aa=Request.Form["t1"]==null?"":Request.Form["t1"].ToString();
1、使用明文串：2.aspx?name=XXX,在第二个页面中再分析；
2、使用页面投递，个人认为这是不错的选择，因为复杂的值传递也很麻烦，比如时间一类的：在1.aspx中写属性：
public string t1_value
{
get{return t1.text;}
}2.aspx中写：
<%@ PreviousPageType VirtualPath="~/1.aspx" %>cs页面的Load：
if (!Page.IsPostBack)
{
if (PreviousPage != null)
{
string _str = PreviousPage.t1_value;
}}
Response.Redirect("2.aspx");
改为:
Server.Transfer("2.aspx");
