    @Session["s1"] 
     @Session["s2"]
    
       </div>

Can someone tell me that why Session Variable is still null

推荐答案

由于你没有使用它的外观任何模型绑定，试试这个：

Since you're not using any model binding by the looks of it, try this:

public ActionResult Index2( FormCollection o){
   ViewData["s1"] = o["My"]; 
   ViewData["s2"] = o["My2"]; 
   return View("View2");
}

您好，



您所关注的流程在这里是错误的。您必须使用HTML帮助程序，如

Hello ,

The process you are following is wrong here. You must use the HTML helpers like the

@Html.BeginForm Or Ajax in order to bind your model.

请查看以下链接，以便更好地了解视图和控制器之间的模型传递。

Html.BeginForm（）vs MVC中的Ajax.BeginForm（） [ ^ ]

对于Controller和视图之间的数据传递，你可以使用， ViewData，ViewBag或TempData



希望这有帮助，

谢谢

Please check the below link to get a better understanding on the model pass between view and Controller.
Html.BeginForm() vs Ajax.BeginForm() in MVC[^]
For pass of data between Controller and view you can use, ViewData, ViewBag Or TempData

Hope this helps,
Thanks

你好，



我想你刚刚开始你的MVC开发，我假设你很好奇MVC是如何工作的。



解决问题的步骤： -

1.请用H装饰你的Index2动作ttpPost属性。



注意： -

1.附加调试器以查看作为请求对象发送的所有请求。

2.请注意，您没有母版页或任何其他页面，它具有相同名称的Dom元素，您用于两个输入框。（我的，My2）。

3.使用Request.Params [我的]并检查。



虽然这不是最好的方法，但是对于学习和试验MVC这很好。

但实时项目采用MVC模型粘合剂概念。

Hello,

I think you have just started your MVC development , I assume that you are curious about how MVC works .

Steps to solve your problem :-
1. Kindly decorate your Index2 Action with HttpPost attribute .

Note :-
1. Attach Debugger to see what all are the request which are send as request object .
2. Pls see that you dont have masterpage or any other page ,which has same Dom Element with same name u you have used for two input box.(My,My2).
3. Use Request.Params["My"] and check.

Although this is not best approch but for learning and experimenting MVC this is fine .
but in real time project go with MVC Model binders concept.
