How to open the Database .mdf file without any Server connection

Question

im a newbie at C# and Database's. I need your help. I use Visual Studio C# Gui and SQL Server Managment Studio from Microsoft.

My problem: I have a Database at SQL Server Managment. Im only able to view it when im connectet about Datagridview in Visual Studio C#. (y thats pretty normal). Now, i want to copy the Database file (.mdf and .ldf) and use it, when im not connectet to view it. Only to view.

 SqlCeConnection myConnection2 = new SqlCeConnection(@"Data Source=C:\Users\XX\Desktop\XX\Database.mdf");
                    SqlCeDataAdapter sda = new SqlCeDataAdapter("Select* FROM Database", myConnection2);
                   DataTable dt = new DataTable();
                    myConnection2.Open();
                    sda.Fill(dt);
                    dgv_Test.DataSource = dt;

This is not working!

How can i do it?

Sorry I don't know how to use your SQL without a connection but you could just make a mock repository and put fake data into that. Then you can just call that repo to have a fake database.
