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)
Use Html.RenderPartial for streaming images or other elements that are media-centric or where faster download times are highly important.
有什么开销
MvcHtmlString/StringWriter介绍？使用 Html.RenderPartial 有什么缺点吗？一直以来，如果开销较少？我在 MSDN 上找不到答案:

最佳答案
Html.RenderPartial 比 Html.Partial 快，因为 RenderPartial 可以快速响应输出。
