c# - 将文件上传到 Blob Azure

Question

我正在尝试从 MVC 应用程序将文件上传到 blob Azure，我正在关注 this教程，我被困在这个片段中:

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

如何使 @"path\myfile" 动态化？？如何检索我的文件的真实路径以将其放在那里？我也接受任何其他上传到 blob 的建议 :)

更新

按照建议，我在 View 中添加了代码:

@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 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");
}

Answer 1

HttpPostedFileBase 将包含您需要的信息。具体来说，InputStream 属性将为您提供流

[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
}
