如何从ASP.NET Web API删除Azure Blob？

将图像从我的Web api上传到azure blob存储可以正常工作，但是在尝试删除它们时却出现以下错误：“ Microsoft.WindowsAzure.Storage.dll中发生了'Microsoft.WindowsAzure.Storage.StorageException类型的异常，但是用户代码未处理”

这是我使用的代码：

// Retrieve storage account from connection string.
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
CloudConfigurationManager.GetSetting("StorageConnectionString"));

// Create the blob client.
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

// Retrieve reference to a previously created container.
CloudBlobContainer container = blobClient.GetContainerReference("mycontainer");

// Retrieve reference to a blob named "myblob.txt".
CloudBlockBlob blockBlob = container.GetBlockBlobReference("myblob.txt");

// Delete the blob.
 blockBlob.Delete();

我试图使用的代码来自：https : //azure.microsoft.com/sv-se/documentation/articles/storage-dotnet-how-to-use-blobs/#delete-blobs

任何帮助或输入表示高度赞赏，谢谢！
