asp.net-mvc – Kendo UI异步上传无法在Internet Explorer中运行

我正在尝试在异步模式下使用Kendo UI Upload(MVC包装器).事情似乎在Chrome中运行良好,但在IE中没有这样的运气(截至目前仅在IE 9中测试过).当它启动上传时,我可以看到它命中我的操作方法,并且请求包含我期望的数据,但实际上没有保存任何内容.

代码示例如下：

_EditForm.cshtml(上传的位置)

@(Html.Kendo().Upload()
    .Name(string.Format("upload{0}","background"))
    .Multiple(true)
    .Events(evt => evt.Success("refreshBackgroundImages"))
    .Messages(msg => msg.DropFilesHere("drag and drop images from your computer here")
                        .StatusUploaded("Files have been uploaded"))
    .Async(a => a.AutoUpload(true)
                 .SaveField("files")
                 .Save("UploadImage","Packages",new { siteId = Model.WebsiteId,type = "background" })))

控制器ActionMethod

[HttpPost]
public ActionResult UploadImage(IEnumerable<HttpPostedFileBase> files,Guid siteId,string type)
{
        var site = _websiteService.GetWebsite(siteId);
        var path = Path.Combine(_fileSystem.OutletVirtualPath,site.Outlet.AssetBaseFolder);
        if (type == "background")
        {
            path = Path.Combine(path,_backgroundImageFolder);
        }
        else if (type == "image")
        {
            path = Path.Combine(path,_foregroundImageFolder);
        }
        foreach (var file in files)
        {
            _fileSystem.SaveFile(path,file.FileName,file.InputStream,file.ContentType,true);
        }
        // Return empty string to signify success
        return Content("");
}

var filename = Path.GetFileName(file.FileName);
