Question

我有一个简单的文件上传示例，我在ASP.NET 1中制作，2在razor中工作3，它不起作用

使用此代码上传文件不能用于3甚至工作1或MVC 2版本

 HttpPostedFileBase file = Request.Files["file"];
            if (file.ContentLength > 0) // accept the file 
            {
                string filename = Server.MapPath("~" + "/upload/" + file.FileName);
                file.SaveAs(filename);
            }
            ViewBag.filelocate = "/upload/" + file.FileName;
            return View();

是他们在asp.net MVC 3中将我的应用程序的上传文件夹中的文件上传的任何方式

Answer 1

我认为这是浏览器发送完整文件路径的问题试试这个：

if (file.ContentLength > 0)
{ 
 string filename = Server.MapPath("~" + "/upload/" + System.IO.Path.GetFilename(file.FileName)); 
 file.SaveAs(filename); Line 24:             
}

Answer 2

您确定在HTML表单上指定了正确的MIME类型吗？它必须是“multipart / form-data”
