在 Xamarin 应用程序中实例化 CloudStorageAccount 会导致未处理的异常

Posted 2023-04-13

【中文标题】在 Xamarin 应用程序中实例化 CloudStorageAccount 会导致未处理的异常

【英文标题】：Instantiating CloudStorageAccount in Xamarin application causes unhandled exception

【发布时间】：2017-10-07 22:08:52

【问题描述】：

在this 文章之后，我创建了一个空白 Xamarin 表单应用程序，将 WindowsStorage.Azure 包添加到 PCL 和 android 应用程序（我现在删除了 ios 和 UWP，因为它只是一个测试应用程序）

  <package id="WindowsAzure.Storage" version="8.1.1" targetFramework="portable45-net45+win8+wp8+wpa81" />

并尝试与库进行交互，但只要我做任何事情，应用程序就会崩溃并出现未处理的异常：

无论我做什么，创建一个新的 StorageCredentials 对象：

var creds = new StorageCredentials("something", "other");

或新的 CloudStorageAccount：

var storageAccount = CloudStorageAccount.Parse(storageConnectionString);

我也一样。 我已经阅读了github documentation 并看不出这是什么原因。

有没有人遇到过这个问题，可以帮忙看看这里出了什么问题？

编辑：

我可以从 debu 窗口看到它抛出了 NotImplementedException：

【问题讨论】：

尝试查看调试/输出窗口以获取有关错误的更多信息。有时您确实需要点击“继续”才能显示。但在一个疯狂的猜测（没有任何进一步的信息），除了 pcl 之外，您是否将 azure 存储包添加到您正在启动的本机。

【参考方案1】：

...为您解决方案中的所有项目安装最新的稳定版本...

回复：步骤 3 https://docs.microsoft.com/en-us/azure/storage/storage-xamarin-blob-storage

Azure 存储使用本机功能/特性，因此您不仅需要在 PCL 项目中安装包，还需要在每个本机应用程序项目中安装包。
