如何在ASP.NET MVC中的请求之间存储数据? [英] How do I store data between requests in ASP.NET MVC?

问题描述

我的应用程序从USB扫描仪读取条形码.我将它们视为令牌，然后从这些令牌构建命令.在可能的情况下，我需要两次或更多次读取才能创建命令.我需要以某种方式存储以前的读物.如何在两次请求之间保留一些数据?我不要在我的视图中使用这些令牌.

My application reads barcodes from a USB scanner. I treat them as tokens and then build commands from those tokens. There may be a situation that I need 2 or more reads before I can create a command. I need to store previous reads in some way. How can I keep some data between request? I do not to use that tokens in my view.

仅命令的结果可能会显示在视图中.

Only results of commands may be displayed in the view.

推荐答案

TempData 字典是在控制器动作之间存储数据的理想选择.它在发布/重定向/获取"模式中最常用，但可以在此处应用.

The TempData dictionary is ideal for storing data between controller actions. It's most commonly used in the Post/Redirect/Get pattern but could apply here.
