提问by user516883
I am very new to MVC and I am updating a web form application to mvc. I have a shared layout (masterpage in webforms), I would like to set the meta and title information per view but I see no options for this. thanks for any help.
我对 MVC 很陌生，我正在将 Web 表单应用程序更新为 mvc。我有一个共享布局（webforms 中的母版页），我想设置每个视图的元和标题信息，但我看不到此选项。谢谢你的帮助。

Typically, in your layout, you'll have something like this:
通常，在您的布局中，您将拥有如下内容：
<!DOCTYPE html>
<html lang="en">
<head>
<title>@ViewBag.Title</title>
<!-- the rest omitted for brevity -->
The important part is @ViewBag.Title. This bit of razor syntax encodes and writes the value of ViewBag.Title. ViewBagis a property on all razor views to a dynamic type that uses the ViewDatadictionary as its backing store. ViewDatais just a dictionary where you can store random stuff that you want to use in your view.
重要的部分是@ViewBag.Title。这种剃刀语法编码并写入ViewBag.Title. ViewBag是使用ViewData字典作为其后备存储的动态类型的所有 razor 视图的属性 。ViewData只是一个字典，您可以在其中存储要在视图中使用的随机内容。
In your controller, layout, or view, you can get or set ViewBag.Title. Here's an example of how to set it in a view that uses your layout (called _Layout.cshtmlin this example):
在您的控制器、布局或视图中，您可以获取或设置ViewBag.Title. 以下是如何在使用您的布局（_Layout.cshtml在本例中称为）的视图中设置它的示例：
@{
ViewBag.Title = "My View's Title";
Layout = "~/Views/Shared/_Layout.cshtml";
}
You can access the model metadata from ViewData.ModelMetadata. In this example, I enumerate the properties of the model and display the names:
您可以从 访问模型元数据ViewData.ModelMetadata。在此示例中，我枚举模型的属性并显示名称：
<ul>
@foreach (var property in ViewData.ModelMetadata.Properties)
{
<li>@property.PropertyName</li>
}
</ul>

In your method of controller.
在您的控制器方法中。
ViewData["Title"] = "this is page one title";
ViewData["Title"] = "this is page one title";
in you view, have this.
@ViewData["Title"])
在你看来，有这个。
@ViewData["Title"])
if title is html, it should be @html.raw(ViewData["TopMessage"])
如果标题是 html，它应该是 @html.raw(ViewData["TopMessage"])
Razor engine is better for mvc, so I recommend you try razor when you create a new project. hope it help you.
Razor 引擎更适合 mvc，所以我建议您在创建新项目时尝试使用 razor。希望对你有帮助。

I like to set page titles dynamically using the action and controller names. You can use a library like Humanizerto convert "SomeActionName" into "Some action name":
我喜欢使用动作和控制器名称动态设置页面标题。您可以使用Humanizer 之类的库将“SomeActionName”转换为“Some action name”：
public static class HtmlHelperExtensions
{
public static MvcHtmlString GetPageTitle(this HtmlHelper helper)
{
var actionName = helper.GetRouteDataValue("action");
var controllerName = helper.GetRouteDataValue("controller");
return new MvcHtmlString(controllerName.Humanize() + " - " + actionName.Humanize());
}
private static string GetRouteDataValue(this HtmlHelper helper, string value)
{
return helper.ViewContext.RouteData.Values[value].ToString();
}
}
and then in your _Layout:
然后在您的 _Layout 中：
<title>@Html.GetPageTitle()</title>
