        string name = null;
        string department = null;
        string listStaff = "MylistStaff";

        string sql =  "SELECT tbl_staff.staffName,tbl_department.department " +
            "FROM tbl_staff,tbl_logs,tbl_department " +
            "WHERE tbl_staff.userID = tbl_logs." + listStaff + " and tbl_staff.idDepartment = tbl_department.idDepartment;";
        //change this connection string... visit www.connectionstrings.com
        string connString = "Server=localhost; Database=myDatabaseName; Trusted_Connection=Yes";
        using (SqlConnection conn = new SqlConnection(connString))
        {
            conn.Open();
            using (SqlCommand command = new SqlCommand(sql,conn))
            {
                SqlDataReader reader = command.ExecuteReader();
                while (reader.Read())
                {
                    name = reader[0] as string;
                    department = reader[1] as string;
                    //break for single row or you can continue if you have multiple rows...
                    break;
                }
            }
            conn.Close();
        }

department and listStaff can then easily be applied to label text like:

DepartmentLabel.Text = department;
