Html.Partial或Html.RenderPartial与MVC3？ [英] Html.Partial or Html.RenderPartial with MVC3?

问题描述

我甚至看到了下面的解释后，我完全糊涂了。

I am totally confused even after seeing the following explanation.

<div>
  @Html.Partial("_FeaturedProduct")
</div>

部分视图可以在里面布局页面渲染（或者如果使用MVC 2/3瓦特/ ASPX，母版页​​），以及定期的意见。

Partial views can be rendered inside a Layout Page (or if using MVC 2/3 w/ASPX, the Master Page) as well as regular views.

有一些情况下，你可能想靠边站，并直接写入到HTTP响应流，而不是一个局部视图渲染的结果（谐音/视图使用MvcHtmlString / StringWriter的）。要做到这一点，使用Html.RenderPartial帮手。

There are some cases where you might like to step aside and write directly to the HTTP Response stream rather than having a partial view render the results (partials/views use MvcHtmlString/StringWriter). To do so, use the Html.RenderPartial helper.

<div>
  @Html.RenderPartial("_FeaturedProduct")
</div>

谁能告诉我这是什么意思？什么情况下，我可能会喜欢写直接到HTTP响应等。如果我的局部视图只包含一行是这样的：

Can someone tell me what it means? What cases where I might like to write direct to the HTTP Response etc. What if my partial view contains just one line like this:

<h1>Hello</h1>

我应该使用，为什么哪？如果我用其他的，会发生什么？

Which should I use and why? What would happen if I used the other?

以下困惑我更加：使用Html.RenderPartial流媒体图像或在媒体中心或者更快的下载时间是非常重要的元素。

The following confused me even more: "Use Html.RenderPartial for streaming images or other elements that are media-centric or where faster download times are highly important."

推荐答案

请参见下面的响应。

唯一的区别是部分返回一个MvcHtmlString，并且必须
  在里面＆LT调用;％=％>，而的RenderPartial returnsvoid并呈现
  直接到视图。

The only difference is that Partial returns an MvcHtmlString, and must be called inside <%= %>, whereas RenderPartial returnsvoid and renders directly to the view.

如果你看一下源$ C ​​$ C，你会发现它们都调用
  同样的内部方法，传递一个StringWriter的为它渲染到。

If you look at the source code, you'll see that they both call the same internal method, passing a StringWriter for it to render to.

如果您想要查看，保存或操纵你会打电话偏
  生成的，而不是将它们写入HTML页面。

You would call Partial if you want to view, save, or manipulate the generated HTML instead of writing it to the page.
