HttpPostedFileBase always null when upload file by asp.net mvc4 mobile

困擾了很久的問題，終於解決了，解決方案串連：

http://stackoverflow.com/questions/13292173/asp-net-mvc-razor-uploading-file-httppostedfilebase-always-null

 

 

@using(Html.BeginForm("Import","Home",FormMethod.Post,new{ enctype ="multipart/form-data"})){<input type="file" name="uploadFile"/><input type="submit" value="Importa"/>}

　　

[AcceptVerbs(HttpVerbs.Post)] // or [HttpPost], nothing changespublic ActionResult Import(HttpPostedFileBase uploadFile){   Debug.WriteLine("Inside Import");   if (uploadFile == null)       Debug.WriteLine("null");   // Verify that the user selected a file   if (uploadFile != null && uploadFile.ContentLength > 0)   {      Debug.WriteLine("Valid File");      ...   }}

　　

需要在View中添加

@data_ajax="false"

。

呼，舒服~
