これは私が使用しているメソッドです。MobileServiceInvalidOperationException Azureからデータを取得しようとするとき
try
{
List<Patient> pList = await App.MobileService.GetTable<Patient>().Where(
patient => patient.id == 1).ToListAsync();
foreach (Patient p in pList)
{
System.Diagnostics.Debug.WriteLine("{0}, {1}", p.id, p.first_name);
}
}
catch (Exception err)
{
System.Diagnostics.Debug.WriteLine("ERROR! : {0}", err.Message);
}
ここには患者エンティティがあります。
class Patient
{
public int id { get; set; }
public string first_name { get; set; }
public string last_name { get; set; }
public string middle_name { get; set; }
public string nirc { get; set; }
public int bed_id { get; set; }
}
ここではエラーが発生しています。私はTryCatch以内に私の方法をラップする場合

注意すべきいくつかのポイントがあります取得します。
- 許可は
Anybody with the Application Key
- に設定されている私は既にApp.XAML.CS.内にこのコードを挿入した
Windows Azure Mobile Services Managed Client
- への参照を追加しました
using Microsoft.WindowsAzure.MobileServices;
- 私は既にthisウェブサイトから取得したこのコードをApp.XAML.CS内に配置しました。
public static MobileServiceClient MobileService = new MobileServiceClient(AppUrl, AppKey);
なぜ私は私のデータベースに接続することができませんか。私はこれらのコードをWindows Storeアプリケーションで実行しようとしました。以前はまったく同じことをやっていましたが、うまくいきました。
これは問題を「解決」しないため、回避します。これにより、HTTPSが無効になり、データがクリアテキストで送信されるようになりました。これはおそらく良いことではありません。私の場合、HTTPSが失敗したデバイスで日付/時刻が間違っていました。 –
