问题
I am looking for ways to store data in a Windows Forms application in .NET. I want to make the input data of a system persistent, so when I close my program and open it again, the data is retrieved.
Which ways of doing this exist besides creating a linked database? Examples are gladly appreciated.
回答1:
There are dozens of different ways to store data. It completely depends on what data. Is it:
- Just a couple of configuration values? Use the built-in Settings library.
- Machine-wide configuration? Use the registry.
- Transactional? Use a relational database.
- Related but not transactional? Use a lightweight database like SQLite or SQLCE.
- Structured but not related? Use XML or JSON files.
- Somewhat structured and high in volume? Use a NoSQL solution like MongoDB.
And so on... there are different solutions for every storage requirement and many projects make use of more than one at a time.

An easy way would be to make use of XML.
Using XML in C# in the simplest way
Read/Write Xml document with FileStream
回答3:
If your data is not mission critical (e.g. user preferences), you could just serialise your objects to file, and de-serialise them next time the app is loaded.
回答4:
Examples? Do your homework yourself :)
Anyhow, possible ways are:
- Registry.
- Files. Like Microsoft Word does. Or like an ini file, like most games do for example for their settings
- Databaase
Which makes sense depends on what the application DOES and other scenarios around it. A fast answer is not really possible without knowing more.
