Jak napisać " Html.BeginForm " w Razor
Jeśli napiszę TAK:
To działa.Form action = "Images" method = "post" enctype= "multipart/form-data"
Ale w Razor Z ' @ ' to nie działa. Popełniłem jakieś błędy?
@using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
Mój kontroler wygląda tak:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Upload()
{
foreach (string file in Request.Files)
{
var uploadedFile = Request.Files[file];
uploadedFile.SaveAs(Server.MapPath("~/content/pics") +
Path.GetFileName(uploadedFile.FileName));
}
return RedirectToAction ("Upload");
}

Następujący kod działa dobrze:
@using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
I generuje zgodnie z oczekiwaniami:
<form action="/Upload/Upload" enctype="multipart/form-data" method="post">
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
</form>
Z drugiej strony, jeśli piszesz ten kod w kontekście innej konstrukcji po stronie serwera, takiej jak if
lub foreach
, powinieneś usunąć @
przed using
. Na przykład:
@if (SomeCondition)
{
using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
}
Jeśli chodzi o kod po stronie serwera, oto Jak postępować :
[HttpPost]
public ActionResult Upload(HttpPostedFileBase file)
{
if (file != null && file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
file.SaveAs(path);
}
return RedirectToAction("Upload");
}
