My application reads barcodes from USB scanner. I treat them as tokens and then build commands from those tokens. There maybe a situation that I need 2 or more reads before I can create a command. I need to store previous reads in some way. Actually what is the correct way to keep some data between request? I do not to use that tokens in my view.
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。在创建命令之前，我可能需要2次或更多次读取。我需要以某种方式存储以前的读取。实际上，在请求之间保留一些数据的正确方法是什么？在我看来，我不会使用这些令牌。
Only results of commands may be displayed in the view.
只有命令的结果可能会显示在视图中。

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.
TempData字典非常适合在控制器操作之间存储数据。它最常用于Post / Redirect / Get模式，但可以在此处应用。

Here are a couple of possibilities that come to mind:
以下是一些可能的想法：
On the client:
在客户端：
- Cookie
- 曲奇饼
- Hidden fields
- 隐藏的领域
On the server:
在服务器上：
- Cache (make sure to use user specific key to avoid collisions)
- 缓存（确保使用用户特定的密钥以避免冲突）
- Some backend storage (such as a database)
- 一些后端存储（例如数据库）
- ASP.NET Session
- ASP.NET会话
