选择上传文件：<input name="file" type="file" id="file" /> </div> <p> <input type="submit" value="Create" /> </p> </fieldset>
}
controller：
// POST: /Question/Create Question question,
[HttpPost]
public ActionResult Create(Question question, HttpPostedFileBase file)
{
try
{
if (ModelState.IsValid)
{
if (file !=null && file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(Server.MapPath("~/Resources"), fileName);
file.SaveAs(path);
QuestionResource resource = new QuestionResource();
resource.Url = path;
question.Resources.Add(resource);
}
unitOfWork.QuestionRepository.Insert(question);
unitOfWork.Save();
return RedirectToAction("Index");
}
}
catch(Exception ex)
{
//Log the error (add a variable name after DataException) ModelState.AddModelError("", question.Title + " " + question.Description + " " + file.ContentLength + " " + ex.Message + " Unable to save changes.");
}
return View(question);
}
在控制器中：HttpPostedFileBase file获取不到上传的文件。调试显示null。
如何获取到上传的文件？谢谢
