I´ve got the following connectionstring: 

string connectionstring = "Data Source=.\\SQLEXPRESS;AttachDbFilename=C:\\Users\\Harald\\Desktop\\Farmer´s Calc\\Programmierung\\WPF\\Finanz_WPF\\Finanz_WPF\\Datenbank\\FarmersCalc.mdf;Integrated Security=True;User Instance=True";

I need to make it dynamic, not the whole path should be included…
I tried it with |DataDirectory| but it seems to work just in ASP.NET.

How can I manage this?
