Question

The connection always times out without generating an error message even though it is within trycatch. I suspect there is something wrong with the connection string. This is what I currently have:

            string path = @"C:\PATH\TO\wantedDB.mdb";

            if (!File.Exists(path))
                throw new FileNotFoundException("File not found.");
            else
                Console.WriteLine("File found."); // File is found, so nothing wrong with that.

            string connectionstring = "Database=wantedDB;AttachDBFilename=" +
            path + ";Server=(local)";

            using (SqlConnection conn = new SqlConnection(connectionstring))
            {
                Console.WriteLine("Opening connection...");
                conn.Open();
                Console.WriteLine("Connection opened."); // Program never gets here.

I have also tried a relational path in connection string like:

string connectionstring = "Database=wantedDB;AttachDBFilename=\"wantedDB.mdb\";Server=(local)";

The db is not protected by a password. I have MS Access installed, does that affect this somehow? What am I missing?

To connect to a mdb file you should use the OLEDB connector:

var con = new OleDbConnection("Provider=Microsoft.JET.OLEDB.4.0;" + "data source=C:\\wantedDB.mdb;");
