我已经尝试了所有可以找到的Xamarin存储片段，但Azure从未返回任何内容或存储任何内容。它通常甚至不会抛出任何异常，只是忽略它看起来的大部分代码。
我很喜欢这些：
public async Task<string> TestStorage()
{
CloudBlobContainer container = new CloudBlobContainer(new Uri(Settings.StorageContainerUrl), new StorageCredentials(Settings.StorageAccountName, Settings.StorageAccountKey));
//CloudBlockBlob blob = container.GetBlockBlobReference("mytest2");
//await blob.UploadTextAsync("This is newly uploaded data");
CloudBlockBlob blob = container.GetBlockBlobReference("mytest");
string data = await blob.DownloadTextAsync();
return data;
}
如果我给它一个不正确的StorageContainerUrl或StorageAccountName，那么Azure会抛出一个错误。到目前为止，它必须连接并验证该信息。我还确认，如果我使用不存在的Blob名称，则Azure Storage会抛出StorageException：指定的blob不存在。
但是，如果我给它一个坏的StorageAccountKey，则不会抛出任何异常。
此外，DownloadTextAsync命令不返回现有blob的任何内容 - 实际上它永远不会返回，并且永远不会设置字符串数据。最终抛出异常：

如果我取消注释UploadTextAsync，那么它也什么都不做，并且在Azure上没有创建Blob。
我可能犯了一些简单的错误，但我已经尝试了我发现的每个组合，包括CloudStorageAccount.Parse，CreateCloudBlobClient。我认为我是在正确的轨道上，因为如果我给它一个糟糕的URL或帐户，我将从Azure获得例外。
答案 0 :(得分：1)
似乎异常是由于在Xamarin中尚未实现的散列函数。有关详细信息，请参阅问题：https://github.com/Azure/azure-storage-net/issues/387
解决方案是恢复到Azure Storage 7.2.1，直到修复。
