Question

我有这个控制器：

- (UIStoryboardSegue *)segueForUnwindingToViewController:(UIViewController *)toViewController fromViewController:(UIViewController *)fromViewController identifier:(NSString *)identifier {

    UIStoryboardSegue *theSegue;

    NSLog(@"Unwind called");

    if ([fromViewController isKindOfClass:[SetDetailViewController class]]) {
        theSegue = [ZoomOutSegue segueWithIdentifier:identifier source:fromViewController destination:toViewController performHandler:^(void){}];
    } else {
        theSegue = [super segueForUnwindingToViewController:toViewController fromViewController:fromViewController identifier:identifier];
    }

    return theSegue;
}

这一行

public ActionResult Index(UserDetails user)
        {
            user.UserEmail = "Email";
            return View();
        }

如何从视图中的控制器（在UserEmail的输入框中）中过去一个值？

感谢您的帮助斯蒂芬

Answer 1

将UserDetails对象传递给视图。

public ActionResult Index(UserDetails user)
{
   user.UserEmail = "Email";
   return View(user);
}

假设您的剃刀视图（Index.cshtml）强烈输入UserDetails

@model UserDetails 
@Html.DisplayNameFor(model => model.UserEmail)
@Html.EditorFor(model => model.UserEmail)

Answer 2

有多种方法可以将值从控制器传递到视图..我会使用viewData和viewBag：

public ActionResult Index(UserDetails user)
    {
        user.UserEmail = "Email";
        ViewData["ArbitraryName"] = user;
        return View();
    }

在您看来：

@Html.DisplayNameFor(model => model.UserEmail)
@Html.EditorFor(model => model.UserEmail)
@{ var user = ViewBag.ArbitraryName;}

要从那里访问特定数据，请使用@user.YourData
