二维会话变量 [英] Two Dimension Session variable
问题描述
你好
我的代码
protected void RadioButton1_CheckedChanged（object sender，EventArgs e）
{
RadioButton rb1 = null;
RadioButton rb2 = null;
RadioButton rb3 = null;
RadioButton rb4 = null;
RadioButton rb5 = null;
RadioButton rb6 = null;
foreach（dlDisplayAll.Items中的DataListItem项目）
{
rb1 =（RadioButton）item.FindControl（RadioButton1）;
rb2 =（RadioButton）item.FindControl（RadioButton2）;
rb3 =（RadioButton）item.FindControl（RadioButton3）;
rb4 =（RadioButton）item.FindControl（RadioButton4）;
rb5 =（RadioButton）item.FindControl（RadioButton5）;
rb6 =（RadioButton） item.FindControl（RadioButton6）;
if（rb1.Checked == true）
{
Session [Size] =Small;
}
else if（rb2.Checked == true）
{
Session [Size] =Medium;
}
else if（rb3.Checked == true）
{
Session [Size] =Large;
}
else if（rb4.Checked == true）
{
Session [Size] = XL;
}
else if（rb5.Checked == true）
{
Session [大小] =XXL;
}
否则if（rb6.Checked == true）
{
会话[大小] =XS;
}
}
}
和viewcart.cs文件
str11 + =
| < input type =''Text''id =''size+ cnt1 +''value =+ Session [Size]。ToString（）+readonly> |
现在当我在购物车中添加一个项目时，它会显示所有尺寸为ID等的信息。现在我继续购物并在购物车中添加新商品，而不是两个商品的尺寸相同，因为我使用了会话[尺寸]一个会话现在我怎么能用它的产品id
Hello
My Code
protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
{
RadioButton rb1 = null;
RadioButton rb2 = null;
RadioButton rb3 = null;
RadioButton rb4 = null;
RadioButton rb5 = null;
RadioButton rb6 = null;
foreach (DataListItem item in dlDisplayAll.Items)
{
rb1 = (RadioButton)item.FindControl("RadioButton1");
rb2 = (RadioButton)item.FindControl("RadioButton2");
rb3 = (RadioButton)item.FindControl("RadioButton3");
rb4 = (RadioButton)item.FindControl("RadioButton4");
rb5 = (RadioButton)item.FindControl("RadioButton5");
rb6 = (RadioButton)item.FindControl("RadioButton6");
if (rb1.Checked == true)
{
Session["Size"] = "Small";
}
else if (rb2.Checked == true)
{
Session["Size"] = "Medium";
}
else if (rb3.Checked == true)
{
Session["Size"] = "Large";
}
else if (rb4.Checked == true)
{
Session["Size"] = "XL";
}
else if (rb5.Checked == true)
{
Session["Size"] = "XXL";
}
else if (rb6.Checked == true)
{
Session["Size"] = "XS";
}
}
}
and in viewcart.cs file
str11 += "
| <input type=''Text'' id=''size" + cnt1 + "'' value=" + Session["Size"].ToString() +" readonly> |
now when i add one item in cart it display all information with size id etc. now i continue shopping and add new item in cart than size of both item gone same because i used Session[Size] one session now how i can do size with it''s product id
推荐答案
你只能在一个条件下传递几乎所有的会话变量：对象应该是< I>可序列化的。这不合乎逻辑吗？
这里有很好的解释： http://msdn.microsoft.com/en-us/library/ms178581%28v=vs.100%29.aspx [ ^ ]。

You can pass nearly anything as a session variable, under only one condition: the object should be serializeable. Isn''t this logical?
This is well explained here: http://msdn.microsoft.com/en-us/library/ms178581%28v=vs.100%29.aspx[^].
