Difference between Html.RenderAction and Html.Action

Question

Does anybody know what's the difference between Html.RenderAction and Html.Action?

Solution 1

Html.Action() – Outputs string

Html.RenderAction() – Renders directly to response stream

If the action returns a large amount of HTML, then rendering directly to the response stream provides better performance than outputting a string.

Solution 2

The difference between the two is that Html.RenderAction will render the result directly to the Response (which is more efficient if the action returns a large amount of HTML) whereas Html.Action returns a string with the result.

So when would you use Html.Action if RenderAction gives better performance?

[David Kassa]

@user76071 from another question with Action you can put the result in a variable or return it from a function.

Better performance? Barely. This is a bad case of premature optimization. Unless you are outputting a huge wiki article, the differences are negligible. Personally, I find Html.Action more readable and only use Html.RenderAction if I am in a code block.

Below article In answer below, states RenderAction is better when rendering a lot of HTML, (like a partial View.) That's why I like it better.
