字符串，对象＆gt;匿名类和的IDictionary℃之间的差异;在ASP.NET MVC htmlAttributes？

问题描述：

例如，如果您选中这两个扩展方法，唯一的区别是htmlAttributes的类型，因此你可以通过你的htmlAttributes两种不同的方式：

For example if you check these two extension methods the only difference is type of htmlAttributes so you can pass your htmlAttributes in two different ways:

public static MvcHtmlString TextBoxFor<TModel, TProperty>(
    this HtmlHelper<TModel> htmlHelper,
    Expression<Func<TModel, TProperty>> expression,
    IDictionary<string, object> htmlAttributes);

public static MvcHtmlString TextBoxFor<TModel, TProperty>(
    this HtmlHelper<TModel> htmlHelper,
    Expression<Func<TModel, TProperty>> expression,
    object htmlAttributes);

和通过下列方式使用它们：

And use them in either of these ways:

@Html.TextBoxFor(model => model.TagLine,
    new { @placeholder = "We live to make art." })

@Html.TextBoxFor(model => model.TagLine,
    new Dictionary<string, object> { 
        { "placeholder", "We live to make art." } })

我已经检查MVC源$ C $ c和我知道他们使用同样的方法为背景，但它接受匿名对象使用一个 HtmlHelper.AnonymousObjectToHtmlAttributes（htmlAttributes）使匿名对象字典。

在我的角度来看，视图是清洁剂使用匿名对象。你怎么看你们？是否有任何缺点，使用一个匿名对象？

In my point of view, views are cleaner to use anonymous object. What do you think guys? Are there any drawbacks to using an anonymous object?

答

有没有太多的区别，但用匿名对象是调用者更清洁，更可读的语法，现在算是比较标准的做法。有可能是轻微的，可以忽略不计的性能优势，如果你是微优化的风扇使用的IDictionary。

There's not too much difference, however using the anonymous object is a cleaner and more readable syntax for the caller, and now considered more standard practice. There might be a slight, negligible performance benefit to using IDictionary if you're a fan of micro-optimisation.

在IDictionary的超载选项卡可能因为ASP.NET MVC 1.0 CTP天，当C＃3.0和匿名对象仍然很新。 Eilon立顿的博客文章建议Using C＃3.0匿名类型的字典给出了一些背景。

The IDictionary overload option has probably stuck since ASP.NET MVC 1.0 CTP days when C# 3.0 and anonymous objects were still quite new. Eilon Lipton's blog post proposing Using C# 3.0 Anonymous Types as Dictionaries gives some background.
