如何使用C＃将已登录用户的信息存储在桌面应用程序中

Question

We want to keep track of which User is logged in at the moment. Instead uf using for example: Environment.Username we want to know the Username from our database. We are able to get the Username from the database but we want to store it somewhere. Any solutions?

Answer 1

An example from the question linked below:

Settings.Default["SomeProperty"] = "Some Value";
Settings.Default.Save(); // Saves settings in application configuration file

I recommend to have a glance at this question .

Best practice to save application settings. There are other solutions as well.

Answer 2

They are several solutions:

• Using MVVM, create shared user manager service(recommended).

• Singleton service.

• Application settings.

• Static variable.

Answer 3

如果您的应用程序由多个用户使用，则您可以将数据存储在CSV，XML等传统文件中。但是，使用这种技术可能无法获得数据安全性，因此可以使用二进制序列化。
