Question

我正在尝试将视频上传到Windows Azure媒体服务。使用Microsoft提供的示例我收到错误System.Collections.ListDictionaryInternal。但是，当我将此行从var uploadFilePath = Path.GetFileName(FileUpload1.PostedFile.FileName);更改为var uploadFilePath = Path.GetFileName(@"c:\video\ocean.mp4");时。文件上传，它工作正常。

<code>
        try
        {
            var uploadFilePath = Path.GetFileName(FileUpload1.PostedFile.FileName);
            var context = new CloudMediaContext("123media", "###############");
            var uploadAsset = context.Assets.Create(Path.GetFileNameWithoutExtension(uploadFilePath), AssetCreationOptions.None);
            var assetFile = uploadAsset.AssetFiles.Create(Path.GetFileName(uploadFilePath));
            assetFile.Upload(uploadFilePath);
            StatusLabel.Text = "Upload status: File uploaded!";
        }
        catch (AggregateException ex)
        {
            StatusLabel.Text = ex.Data.ToString();
        }

 <form id="form1" enctype="multipart/form-data" runat="server">
<div>    
<asp:FileUpload ID="FileUpload1" CssClass="btn-button" runat="server" Width="325px" />
<asp:Button runat="server" id="UploadButton" text="Upload" onclick="UploadButton_Click" />
<br />
<br />
<asp:Label runat="server" id="StatusLabel" text="Upload status: " />
</div>
</form>

这是FileName HttpPostedFile的PostedFile属性（其类型是FileUpload控件的save the uploadedfile属性）实际上是完全限定的名称服务器上的文件，不。

您必须在本地首先my Sample MVC based project使用相同的名称，然后将其传递给AssetFile对象进行上传。

有些人尝试修复代码：

    try
    {
        var fileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
        var serverFileName = Server.MapPath("~/" + fileName);
        FileUpload1.PostedFile.SaveAs(serverFileName);
        var context = new CloudMediaContext("123media", "###############");
        var uploadAsset = context.Assets.Create(Path.GetFileNameWithoutExtension(fileName), AssetCreationOptions.None);
        var assetFile = uploadAsset.AssetFiles.Create(fileName);
        assetFile.Upload(serverFileName);
        StatusLabel.Text = "Upload status: File uploaded!";
    }
    catch (AggregateException ex)
    {
        StatusLabel.Text = ex.Data.ToString();
    }

你能引用一下你从哪里得到这个示例代码？顺便说一句，你可以得到{{3}}。我大约3个月前更新了它，所以一定要工作。
