asp.net-mvc-2 - CreateIfNotExists 的命名空间是什么？

Question

在我的应用程序中，我尝试将文档上传到 Azure blob 存储。代码是:

// Namespaces for Azure
using Microsoft.WindowsAzure;
using Microsoft.WindowsAzure.StorageClient;

public ActionResult GetPdf(HttpPostedFileBase document)
{
    int pdfocument = Request.ContentLength;

    var doctype=Request.ContentType;

    byte[] pdf = new byte[pdfocument];               
    CloudStorageAccount storageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("Setting1"));
    CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();           
    CloudBlobContainer container = blobClient.GetContainerReference("containername");
    container.CreateIfNotExists();
    var permissions = container.GetPermissions();
    permissions.PublicAccess = BlobContainerPublicAccessType.Blob;
    container.SetPermissions(permissions);
    string uniqueBlobName = "blobname";
    CloudBlockBlob blob = container.GetBlockBlobReference(uniqueBlobName);
    blob.Properties.ContentType = doctype;
    blob.UploadByteArray(pdf);
}

当我构建应用程序时，我在 container.CreateIfNotExists() 处收到错误。错误是:

'Microsoft.WindowsAzure.StorageClient.CloudBlobContainer' does not contain a definition for 'CreateIfNotExists' and no extension method 'CreateIfNotExists' accepting a first argument of type 'Microsoft.WindowsAzure.StorageClient.CloudBlobContainer' could be found (are you missing a using directive or an assembly reference?)'.

我可以为该错误添加哪个命名空间？

CreateIfNotExists 是 Azure 库 2.0 版的一部分。

如果您使用 1.7 版 StorageClient 命名空间，则需要调用 CreateIfNotExist(无复数)
