在Windows窗体应用程序中获取当前路径无法正常工作

Question

I'm working on an app linked to a local db and I'd like to get the path of db d y namically. I don't know where exactly users will copy this app, so I'd like to get the path to the db automatically. I wrote the following code, it gets the path, but not exactly. I mean, if I have my app in: C:\\Users\\ROG\\Desktop , it says that there is no db in C:\\Users\\ROG . So it doesn't get the last location of it. Why is that and how to solve it?

I connect to it as follow:

var connString = (@"Data Source=" + 
                  Directory.GetParent(Directory.GetCurrentDirectory()).Parent.FullName + 
                  @"\Angajati.sdf");

Answer 1

try to use the following code

var connString = (@"Data Source=" + 
                  System.IO.Path.Combine(System.IO.Path.GetDirectoryName(
                         System.Reflection.Assembly.GetExecutingAssembly().Location),
                  "Angajati.sdf"));

Answer 2

Rather than using get current directory I suggest using Application Path. That's because if an OpenFileDialog be used the current directory changes but the applicationPath is the same.

System.Reflection.Assembly.GetExecutingAssembly().Location

I hope it would be helpful.

Answer 3

Consider using the following code to determine appllication base directory:

AppDomain.CurrentDomain.BaseDirectory

Full code will look like the following:

var connString = "Data Source=" + 
              System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Angajati.sdf");
