何时在MVC 4 Razor中使用@Model和Model [英] When to use @Model and Model In MVC 4 Razor

问题描述

在我的PartialView中使用VS 2013，C#，我有以下内容；

Using VS 2013, C#, in my PartialView I have the following;

@model MyProject.Models.MyObject

我可以通过以下方式访问模型属性:

I can access the model properties by;

@Model.MyProperty

或

Model.MyProperty

我注意到，如果我不使用@Model，则不会获得显示对象属性名称的IntelliSense.除此之外，它们的工作原理完全相同.

I noticed that if I don't use the @Model, I don't get the IntelliSense to show the object property names. Apart from that they both work exactly the same.

因此，什么时候应该使用@ Model.MyProperty，什么时候应该仅使用Model.MyProperty?

Therefore when should I use @Model.MyProperty and when should I use just Model.MyProperty?

推荐答案

"@"符号告诉Razor View Engine后面有一个内联表达式.但是引擎足够聪明，在某些情况下您不需要'@'符号.例如，在简单的代码块中，例如

The '@' sign tells the Razor View Engine that an inline expression follows. But the engine is smart enough that you don't need the '@' sign in some cases. For example in simple code blocks like

@{ 
  int x = 123; 
  string y = Model.AStringProperty;
}

或者如果您以后使用多个Razor/C#语句:

or if your are using multiple Razor/C# statements after another:

@for (var i = 0; i < Model.List.Count(); i++) {
        var image = Model.List[i];

        <div class="item @(i == 0 ? "active" : "")">
        (... other stuff ...)
        </div>
 }

有点奇怪的是，您没有获得IntelliSense-您应该获得IntelliSense.

What's a little bit strange is that you don't get IntelliSense - you should get one.

因此，(运行时)编译器会告诉您何时使用"@"符号.

So the (runtime)compiler will tell you when to use the '@' sign or not.
