我正在开发我的第一个ASP.net MVC项目,并且在同一页面中使用多个表单时出现了一些问题.首先我创建了2个部分类:(*注册将允许用户注册,*登录它允许用户登录.)
然后我使用HTML.render将它们集成到我的"Logpage"中.所以我要使用2个不同的动作.像这个:
[HttpPost]
public ActionResult Login(LogModel.Login Model)
{
if (ModelState.IsValid)
{
if (LogModel.Login.Verifuser(Model.IDUser, Model.Password))
{
FormsAuthentication.SetAuthCookie(Model.IDUser, false);
if (LogModel.Login.IsAdmin(Model.IDUser, Model.Password))
{
return View("Admin/Index");
}
else
{
return View("Agence/Index");
}
}
else
{
ModelState.AddModelError("", "Invalide username or Password");
return View(Model);
}
}
return View(Model);
}

我想Html.HiddenFor用预设值设置助手的值,这部分是解决的.这是我的代码:
