将文件上传到Blob Azure [英] Upload file into Blob Azure

问题描述

我正在尝试将文件从MVC应用程序上传到blob Azure中，我在关注

I'm trying to upload files into blob Azure from an MVC app, I'm following this tutorial, and I'm stuck in this snippet:

using (var fileStream = System.IO.File.OpenRead(@"path\myfile"))
{
    blockBlob.UploadFromStream(fileStream);
}

如何使@"path\myfile"动态?如何检索文件的真实路径以将其放入其中?我也接受任何其他建议以上传到blob:)

How to make @"path\myfile" dynamic?? How to retrieve the real path of my file to put it in there? I accept any other suggestion too to upload to blob :)

更新

根据建议，我在视图中添加了代码:

As suggested I added the code inside my View:

@model RiPSShared.Models.RiPSModels.AgencyNote

<h2>PostFile</h2>

<form action="@Url.Action("PostFile", "AgencyNotes", new { NoteId=Model.aut_id})" method = "post" enctype="multipart/form-data">
    <label for="file1"> File name:</label>
    <input type="file" name="file" id="file1" />
    <input type="submit" value="Submit" />    
</form>

以及完整的动作控制器:

And the full action controller:

 public ActionResult PostFile(HttpPostedFileBase file, int NoteId)
 {
 CloudBlockBlob blockBlob = container.GetBlockBlobReference(path);
 using (Stream fileStream = file.InputStream)
            {
                blockBlob.UploadFromStream(fileStream);
            }
 return RedirectToAction("Index");
}

推荐答案

HttpPostedFileBase将提供您所需的信息.具体来说，InputStream属性将为您提供视频流

HttpPostedFileBase will have the information you need. Specifically the InputStream property will give you the stream

[HttpPost]
public ActionResult PostFile(HttpPostedFileBase file, int NoteId)  
{   
    // Your existing code for azure blob access
    CloudBlockBlob blockBlob = container.GetBlockBlobReference("myblob");
    // make sure to a null check on file parameter before accessing the InputStream

    using (var s = file.InputStream)
    {
       blockBlob.UploadFromStream(s);
    }
    // to do :Return something
}
