这是我正在使用的方法。
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);
}
这是患者实体。
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; }
}
这是我收到的错误。

当我将方法包装在 TryCatch 中时,我收到此消息
Error : The request could not be completed. ()
这是堆栈错误消息

有几点需要注意
- 权限设置为
任何拥有应用程序 key 的人
- 我添加了对
Windows Azure 移动服务托管客户端
的引用 - 我已将此代码插入到 App.XAML.CS 中。
使用 Microsoft.WindowsAzure.MobileServices;
- 我已经放置了从 this 获取的这段代码App.XAML.CS 内的网站。
public static MobileServiceClient MobileService = new MobileServiceClient( AppUrl, AppKey );
为什么我无法连接到我的数据库?我尝试在 Windows 应用商店应用程序上运行这些代码并且它有效。以前我也做过同样的事情,而且效果也很好。
最佳答案
This链接救了我。
显然,我所要做的就是将服务地址从 https
更改为 http
。所以代替这个,
public static MobileServiceClient MobileService = new MobileServiceClient(
"https://www.example.azure-mobile.net/",
"fjkdslajkfdlsref31321fgdsat34ajklfdslajfkldsa"
);
更改为
public static MobileServiceClient MobileService = new MobileServiceClient(
"http://www.example.azure-mobile.net/",
"fjkdslajkfdlsref31321fgdsat34ajklfdslajfkldsa"
);
问题已解决。
关于c# - 尝试从 Azure 检索数据时出现 MobileServiceInvalidOperationException,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/16909922/
