Asp.net mvc 4 Windows Azure blob压缩并发送到客户端（ASP.NET MVC）

我有一些文件存储在WindowsAzure blob容器中（比如file1.txt和file2.txt）。 在ASP.NETMVC4应用程序（托管在azurewebsites上）中，我需要创建一个“下载为zip”链接。当用户单击它时，他会得到一个包含两个txt文件的zip文件。 我很难编写完成此任务的控制器方法：-（有人能提供简短的示例吗？

非常感谢。

这里有一些代码。代码是原始格式的，请根据您的使用情况进行增强。 我使用了DotNetZip和表存储numget

生成Zip的代码-

    using (ZipFile zip = new ZipFile())
    using(MemoryStream stream = new MemoryStream())
    {
        BlobRepository rep = new BlobRepository();

        // Download files from Blob storage
        byte[] b = rep.DownloadFileFromBlob(filename);

        zip.AddEntry("sample1", b);
        //add as many files as you want

        zip.Save(stream);
        // use that stream for your usage.
    }

下载blob的代码-

public byte[] DownloadFileFromBlob(string filename)
{
    // Get Blob Container 
    CloudBlobContainer container = BlobUtilities.GetBlobClient.GetContainerReference(BlobUtilities.FileContainer);
    // Get reference to blob (binary content) 
    CloudBlockBlob blockBlob = container.GetBlockBlobReference(filename);
    // Read content 
    using (MemoryStream ms = new MemoryStream())
    {
        blockBlob.DownloadToStream(ms);
        return ms.ToArray();
    }
}

Blob实用工具辅助类-

internal class BlobUtilities
{
    public static CloudBlobClient GetBlobClient
    {
        get
        {
            CloudStorageAccount storageAccount = CloudStorageAccount.Parse("connection string here");
            CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
            return blobClient;
        }
    }
    public static string FileContainer
    {
        get
        {
            return "container name here";
        }
    }
}
