c＃winforms GetCurrentDirectory返回C：\\ WINDOWS \\ System32 \\设计错误

Question

I'm making like a cashier app with a winforms project and i need to use an access database and i used System.IO.GetCurrentDirectory() . But it returns C:\\WINDOWS\\System32 on design time so it keeps popping up message boxes when i'm using the designer.

It also returns the correct directory when i run it.

Here's an example of my connection string:

OleDbConnection conn = new OleDbConnection();
string dataPath = System.IO.Directory.GetCurrentDirectory();
conn.ConnectionString = @"
Provider=Microsoft.ACE.OLEDB.12.0;
Data Source=" + dataPath + "/Data/Databases/database.accdb;Persist Security Info=False";

Any help will be appriciated.

Edit:

What happens when i try to open the designer: https://i.stack.imgur.com/HQjHa.png

Not sure why this is happening but u can try :

System.Environment.CurrentDirectory

//or

Application.StartupPath

//or

System.IO.Path.GetDirectoryName(Application.ExecutablePath);

//or

System.IO.Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);

//or

System.AppDomain.CurrentDomain.BaseDirectory
