Try setting up a connection in VS with the Server Explorer pane:
1) Open Server Explorer.
2) Right click "Data connections" and select "Add connection"
3) In the dialog that follows, select your DataSource, and database, specify the security info, and press the "Test connection" button.
4) When the connection works, press "OK"
5) Highlight your database in the Server Explorer pane, and look at the Properties pane. A working example of the connection string will be shown, which you can copy and paste into your app or config file.

Solution 2

as guys said go to this link
http://www.connectionstrings.com/sql-server-compact/[^]

it seems that you need to use following lines to get the right db connection string

string StartupPath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().GetName().CodeBase);

C#

string datalogicFilePath = Path.Combine(StartupPath, "Datalogic.sdf");
string connectionString = string.Format("DataSource={0}", datalogicFilePath);

Keyword not supported: 'datasource'.

string StartupPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);

SqlConnection con = new SqlConnection(string.Format("DataSource={0}", System.IO.Path.Combine(Application.StartupPath, "Database2.sdf")));
