最佳答案
我是MVC 4的新手,我试图实现文件上传控制 我的网站。我找不到错误所在。我得到一个null
控制器:
public class UploadController : BaseController
{
public ActionResult UploadDocument()
{
return View();
}
[HttpPost]
public ActionResult Upload(HttpPostedFileBase file)
{
if (file != null && file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(Server.MapPath("~/Images/"), fileName);
file.SaveAs(path);
}
return RedirectToAction("UploadDocument");
}
}
观点:
@using (Html.BeginForm("Upload", "Upload", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
<input type="file" name="FileUpload" />
<input type="submit" name="Submit" id="Submit" value="Upload" />
}
