MultipartMemoryStreamProvider：文件名？ [英] MultipartMemoryStreamProvider: filename?

问题描述

我已经在这里问我怎么能读取网页API上传的文件，而不需要拯救他们。
这个问题得到的回答与MultipartMemoryStreamProvider，但如何获取文件名用这种方法来从中获得上传文件的类型？

I already asked here how I can read uploaded files in Web Api without the need to save them. This question was answered with the MultipartMemoryStreamProvider, but how do I get the file name with this method to derive the type of the uploaded file from it?

亲切的问候

推荐答案

有在这个DotNetNuke的code <一个例子href=\"https://dotnetnuke.svn.$c$cplex.com/svn/trunk/Community/DotNetNuke.Web/InternalServices/FileUploadController.cs\">here （请参阅 PostFile（）法）。

There is an example in this DotNetNuke Code here (See the PostFile() method).

获得您需要的内容项，然后访问FileName属性。

Get the content item you require and then access the filename property.

事情是这样的：

        var provider = new MultipartMemoryStreamProvider();
        var task = request.Content.ReadAsMultipartAsync(provider).
             ContinueWith(o =>
                 {
                     //Select the appropriate content item this assumes only 1 part
                     var fileContent = provider.Contents.SingleOrDefault();

                     if (fileContent != null)
                     {
                         var fileName = fileContent.Headers.ContentDisposition.FileName.Replace("\"", string.Empty);
                     }
                 }
