推荐答案

我不确定我们是否会根据您的要求知道如何帮助您



（1）..它不清楚你期望申请做什么 - 你的问题n title表示C＃-Win表单，而你的'内容'就像是'桌面应用程序'



（2）Synchronize是一个关于那个的术语有不同的含义 - 有点像'CSV' - 所以描述你想要对数据发生什么



所以，让我们来看看（1）如果你要去设计一个Windows窗体应用程序，你需要做什么？例如



指定Azure数据库和凭证

指定SQLite数据库位置/文件

显示任何错误



（基于此，命令行/控制台应用程序会出现什么问题？）



是该应用程序应该自动运行？或者需要用户输入



如上所述继续进行（2）定义'同步'....你的意思是'做一个完整的副本'从Azure到SQLite - 你的意思是'从Azure更改/添加记录到SQLite'



...你看，它通过写出要求和程序的规范，你开始将其分解为可管理的功能块

Im not sure if we would know how to help you based on your requirements

(1) .. its not clear what you expect the application to do - your question title says C#-Win form, while your 'content' such as it is just says 'desktop application'

(2) Synchronise is a term thats bandied about that has different meaning - a bit like 'CSV' - so describe what you want to happen to the data

So, lets look at (1) if you were going to design a Windows Forms Application, what do you need to do ? For example

Specify Azure Database and Credentials
Specify SQLite Database location/file
Display any errors

(based on this, what would be wrong with a Command-Line/Console Application ?)

Is the application supposed to run Autonomously ? or Needs User Input

And moving on to (2) as I said above, define 'Synchronise' .... do you mean for example 'make a complete copy' from Azure to SQLite - do you mean 'Copy Changed/Added records from Azure to SQLite'

... you see, its by writing out the requirements and the specifications for a program, that you start breaking it down into managable 'chunks' of functionality
