Если вам нужна предварительно загруженная БД, вы можете добавить БД sqlCe в свое приложение и заполнить БД исходными данными.
затем вы можете скопировать файл БД в ваш ISO Store при вызове вашего Конструктора DBContext.
public Moviadb1DataContext (string connectionString) : base(connectionString)
{
IsolatedStorageFile iso = IsolatedStorageFile.GetUserStoreForApplication();
if (!iso.FileExists("Moviadb1.sdf"))
{
MoveReferenceDatabase();
}
if (!DatabaseExists())
CreateDatabase();
}
public static void MoveReferenceDatabase()
{
// Obtain the virtual store for the application.
IsolatedStorageFile iso = IsolatedStorageFile.GetUserStoreForApplication();
// Create a stream for the file in the installation folder.
using (Stream input = Application.GetResourceStream(new Uri("Moviadb1.sdf", UriKind.Relative)).Stream)
{
// Create a stream for the new file in isolated storage.
using (IsolatedStorageFileStream output = iso.CreateFile("Moviadb1.sdf"))
{
// Initialize the buffer.
byte[] readBuffer = new byte[4096];
int bytesRead = -1;
// Copy the file from the installation folder to isolated storage.
while ((bytesRead = input.Read(readBuffer, 0, readBuffer.Length)) > 0)
{
output.Write(readBuffer, 0, bytesRead);
}
}
}
}
Вы также можете добавить некоторые начальные данные вместо перемещения ссылочной БД, если у вас очень маленький объем данных.
public ListenDataDataContext (string connectionString) : base(connectionString)
{
if (!DatabaseExists())
{
CreateDatabase();
List<Audiables> PreLoads = new List<Audiables>();
PreLoads.Add(new Audiables { Category = 1, Name = "I want To Eat", AudioLocation = "Sounds/Food/1_IwantToEat.wma", ImageLocation = "Images/Food/1_IwantToEat.jpg" });
PreLoads.Add(new Audiables { Category = 1, Name = "I want To Drink", AudioLocation = "Sounds/Food/1_IwantToDrink.wma", ImageLocation = "Images/Food/1_IwantToDrink.jpg" });
PreLoads.Add(new Audiables { Category = 2, Name = "I want A Ticket", AudioLocation = "Sounds/Travel/1_IwantATicket.wma", ImageLocation = "Images/Travel/1_IwantATicket.jpg" });
PreLoads.Add(new Audiables { Category = 2, Name = "I want To Sit", AudioLocation = "Sounds/Travel/1_IwantToSit.wma", ImageLocation = "Images/Travel/1_IwantToSit.jpg" });
PreLoads.Add(new Audiables { Category = 3, Name = "How Much Is That", AudioLocation = "Sounds/Shopping/1_HowMuchIsThat.wma", ImageLocation = "Images/Shopping/1_HowMuchIsThat.jpg" });
PreLoads.Add(new Audiables { Category = 3, Name = "Please Take the Money", AudioLocation = "Sounds/Shopping/1_PleaseTakeTheMoney.wma", ImageLocation = "Images/Shopping/1_PleaseTakeTheMoney.jpg" });
Audiables.InsertAllOnSubmit(PreLoads);
this.SubmitChanges();
}
}
Счастливого создания приложения :)
