上传多个文件天青Blob存储 [英] Uploading Multiple Files to Azure Blob Storage

问题描述

漂亮的新的Windows Azure。我已经按照这个教程：的教程。它完美但是一个限制是对我心目中的应用程序，它需要有可能相对快速地上传多个文件。

Pretty new to Windows Azure. I've followed this tutorial: tutorial. It works perfectly however one limitation is that for the application I have in mind, it would need to be possible to upload multiple files relatively quickly.

是否有可能修改教程，支持多文件上传，例如用户可以使用Shift键并单击选择多个文件。

Is it possible to modify the tutorial to support multi-file uploads, e.g. The user can use shift-click to select multiple files..

或者，如果任何人任何好的教程，详细说明上述？

Or if anyone knows of any good tutorials detailing the above?

任何帮助表示赞赏，

感谢

推荐答案

我想看看从DotNetCurry这个教程它展示了如何使用创建多文件上传jQuery来处理文件的多个上传到ASP.NET页面。它使用ASP.NET 3.5建的，但如果你使用.NET 4中不应该的问题 - 没有什么太疯狂了事情

I'd take a look at this tutorial from DotNetCurry which shows how to create a multiple file upload using jQuery to handle the multiple uploading of files to an ASP.NET page. It's built using ASP.NET 3.5, but it shouldn't matter if you're using .NET 4 - there's nothing too crazy going on.

但关键是， jQuery的插件，可以让你的文件集合上传到服务器上。在ASP.NET代码后面将处理由通过 Request.Files 收集循环：

But the key is that the jQuery plug-in will allow you to upload a collection of files to the server. The ASP.NET code behind will handle that by looping through the Request.Files collection:

    HttpFileCollection hfc = Request.Files;
    for (int i = 0; i < hfc.Count; i++)
    {
        HttpPostedFile hpf = hfc[i];
        if (hpf.ContentLength > 0)
        {
            hpf.SaveAs(Server.MapPath("MyFiles") + "\\" +
              System.IO.Path.GetFileName(hpf.FileName));
            Response.Write("<b>File: </b>" + hpf.FileName + " <b>Size:</b> " +
                hpf.ContentLength + " <b>Type:</b> " + hpf.ContentType + " Uploaded Successfully <br/>");
        }
    }

您会将此代码放在您的教程在 insertButton_Click 事件处理程序 - 本质把斑点创作并上传到Blob存储里面，上面的代码的如果（hpf.ContentLength大于0）块

You would put this code in your tutorial in the insertButton_Click event handler - essentially putting the blob creation and uploading to blob storage inside the above code's if(hpf.ContentLength>0) block.

所以伪代码可能看起来像：

So pseudo-code may look like:

protected void insertButton_Click(object sender, EventArgs e)
{
    HttpFileCollection hfc = Request.Files;
    for (int i = 0; i < hfc.Count; i++)
    {
      HttpPostedFile hpf = hfc[i];

      // Make a unique blob name
      string extension = System.IO.Path.GetExtension(hpf.FileName);

      // Create the Blob and upload the file
      var blob = _BlobContainer.GetBlobReference(Guid.NewGuid().ToString() + extension);
      blob.UploadFromStream(hpf.InputStream);

      // Set the metadata into the blob
      blob.Metadata["FileName"] = fileNameBox.Text;
      blob.Metadata["Submitter"] = submitterBox.Text;
      blob.SetMetadata();

      // Set the properties
      blob.Properties.ContentType = hpf.ContentType;
      blob.SetProperties();
    }
}

同样，它只是伪码，所以我中号假设这是它如何工作。我没有测试的语法，但我认为它很接近。

Again, it's just pseudo-code, so I'm assuming that's how it would work. I didn't test the syntax, but I think it's close.

我希望这有助于。祝你好运！

I hope this helps. Good luck!
