Question

我想在我的Enterprise Exchange帐户中创建一个新日历，但我总是获得相同的＆＃34;访问被拒绝＆＃34;例外类型＆＃39; System.UnauthorizedAccessException＆＃39;的例外情况发生在mscorlib.ni.dll但未在用户代码中处理其他信息：拒绝访问。（HRESULT异常：0x80070005（E_ACCESSDENIED））

这是我的代码，这个问题很简单：

private const string ExchangeActiveSync = "{6833942B-ABDA-4C20-9757-4F9252396BD4}";
UserDataAccountStore userDataAccountStore = await UserDataAccountManager.RequestStoreAsync(UserDataAccountStoreAccessType.AllAccountsReadOnly);

//Read-only access to app user data accounts and system user data accounts.
//AllAccountsReadOnly = 0,
//Read/write access to the current app's user data accounts.
//AppAccountsReadWrite = 1
//So AllAccountsReadWrite is missing :(

IReadOnlyList<UserDataAccount> listUserAccounts = await userDataAccountStore.FindAccountsAsync();

string accountId= (from account in listUserAccounts where account.DeviceAccountTypeId.Equals(ExchangeActiveSync) select account.Id).FirstOrDefault();
//accountId = "29,0,af";
string calendarName = Package.Current.DisplayName;
//calendarName = "Test Calendar"

AppointmentStore appointmentStore = await AppointmentManager.RequestStoreAsync(AppointmentStoreAccessType.AllCalendarsReadWrite);

var calendar = await appointmentStore.CreateAppointmentCalendarAsync(calendarName, accountId);
//Here the exception is thrown

calendar.OtherAppReadAccess = AppointmentCalendarOtherAppReadAccess.Full;
calendar.OtherAppWriteAccess = AppointmentCalendarOtherAppWriteAccess.None;
await calendar.SaveAsync();

我还在package.appxmanifest

中添加了必要的限制功能

<rescap:Capability Name="userDataSystem" />
<rescap:Capability Name="userDataAccountsProvider" />
<rescap:Capability Name="appointmentsSystem" />

我认为主要问题出在UserDataAccountStoreAccessType枚举中。在这里，我们错过了＆＃34; AllAccountsReadWrite＆＃34;值（如在日历访问类型中）。我认为这是一个巨大的限制。为什么我无法为帐户创建自定义日历？

我注意到这个限制也在系统日历应用中，所以很糟糕:(

有什么解决方案吗？

非常感谢您的支持。

最好的问候，

我想在我的Enterprise Exchange帐户中创建一个新日历，但我总是获得相同的“拒绝访问”异常mscorlib.ni.dll中出现类型'System.UnauthorizedAccessException'的异常，但未在用户代码中处理其他信息：拒绝访问。（HRESULT异常：0x80070005（E_ACCESSDENIED））

您已使用AppointmentStoreAccessType.AllCalendarsReadWrite访问约会商店。然后您使用CreateAppointmentCalendarAsync(calendarName, accountId)方法创建日历。但您的帐户为ReadOnly。所以它会抛出“拒绝访问”的例外。

如果您想在一个现有的Exchange帐户中创建一个新日历，那么通过我的测试，目前不允许这样做。如果要在属于邮件帐户的现有日历中创建新约会，请参阅以下代码。

IReadOnlyList<AppointmentCalendar> appointmentCalendars = await appointmentStore.FindAppointmentCalendarsAsync();
foreach (AppointmentCalendar calendar in appointmentCalendars)
{
   if(calendar.DisplayName=="Calendar")
    {
        AppointmentCalendar appointmentcalendar = await appointmentStore.GetAppointmentCalendarAsync(calendar.LocalId);
        await appointmentcalendar.SaveAppointmentAsync(appointment);
    }
}
