Question

我尝试使用最新的API收集Windows Mobile 10通话记录。我为我的应用程序启用了所有可能的功能，但我仍然得到了＃34;访问被拒绝＆＃34;运行此代码时出错：

var operation = PhoneCallHistoryManager.RequestStoreAsync(PhoneCallHistoryStoreAccessType.AppEntriesReadWrite);
operation.Completed = (o, ev) =>
{
    PhoneCallHistoryStore store = o.GetResults();
    PhoneCallHistoryEntryReader reader = store.GetEntryReader();

    var operation2 = reader.ReadBatchAsync();
    operation2.Completed = (o2, ev2) =>
    {
        IReadOnlyList<PhoneCallHistoryEntry> callsList = o2.GetResults();
        foreach (PhoneCallHistoryEntry entry in callsList)
        {
            // process calls here
        }
    };
};

我在执行第4行时收到以下错误消息：

An exception of type 'System.UnauthorizedAccessException' occurred in App1.exe but was not handled in user code

Additional information: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

我在Visual Studio 2015中的Mobile Emulator上运行此代码。这就是我用于该代码的内容： https://msdn.microsoft.com/en-us/library/windows/apps/windows.applicationmodel.calls.aspx

知道什么是错的吗？

Answer 1

为了使上述代码正常工作并查看电话通话记录，需要添加以下内容：

1）Rescap名称空间

xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities"

2）受限制的能力“phoneCallHistory”

<rescap:Capability Name="phoneCallHistory"/>

3）将PhoneCallHistoryAccessType更改为AllEntriesLimitedReadAndWrite。

var operation = PhoneCallHistoryManager.RequestStoreAsync(PhoneCallHistoryStoreAccessType.AllEntriesLimitedReadWrite);

感谢@RaymondChen为我提供了正确的功能名称。
