Contoh

Contoh berikut menyediakan metode yang dapat digunakan kembali untuk membuat daftar anotasi, menghapus daftar anotasi tertentu, dan menghapus semua daftar anotasi di penyimpanan.

public async Task<ContactAnnotationList> CreateAnnotationList()
{
    // Get the data store.
    ContactAnnotationStore store = await ContactManager.RequestAnnotationStoreAsync(ContactAnnotationStoreAccessType.AppAnnotationsReadWrite);

    // Create a new list.
    ContactAnnotationList list = await store.CreateAnnotationListAsync();

    // Find the list to verify it was created.
    IReadOnlyList<ContactAnnotationList> lists = await store.FindAnnotationListsAsync();

    for (int i = 0; i < lists.Count; i++)
    {
        // Do the IDs match?
        if (list.Id == lists[i].Id)
        {
            // Found it! Return the new list.
            return(list);
        }
    }

    // List not created, return null.
    return(null);
}

public async Task<Boolean> DeleteAnnotationList(string listId)
{
    // Get the store.
    ContactAnnotationStore store = await ContactManager.RequestAnnotationStoreAsync(ContactAnnotationStoreAccessType.AppAnnotationsReadWrite);

    // Find the list.
    ContactAnnotationList list = await store.GetAnnotationListAsync(listId);

    // Make sure we got it.
    if (list.Id == listId)
    {
        // Delete the list.
        await list.DeleteAsync();
        return true;
    }

    return false;
}

public async Task<Boolean> DeleteAllAnnotationLists()
{
    // Get the store.
    ContactAnnotationStore store = await ContactManager.RequestAnnotationStoreAsync(ContactAnnotationStoreAccessType.AppAnnotationsReadWrite);

    IReadOnlyList<ContactAnnotationList> lists = await store.FindAnnotationListsAsync();

    // Make sure at least one annotation list exists.
    if (lists.Count > 0)
    {
        // Find the list.
        for (int i = 0; i < lists.Count; i++)
        {
            await lists[i].DeleteAsync();
        }

        return true;
    }

    return false;
