which is better to use

哪一个更好用

HTML.Partial and HTML.RenderPartial are methods for rendering partial views in ASP.NET MVC and Core. HTML.Partial returns HTML content as an MvcHtmlString, allowing further manipulation, while HTML.RenderPartial directly writes to the response stream for efficiency. On the other hand, HTML.Action and HTML.RenderAction invoke child action methods. HTML.Action returns a MvcHtmlString, useful for capturing and manipulating output, whereas HTML.RenderAction writes directly to the response stream. The choice depends on your need to capture output and performance requirements. HTML.RenderPartial and HTML.RenderAction are more efficient for direct rendering, while HTML.Partial and HTML.Action offer greater control and flexibility.

HTML.Partial和HTMLRenderPartial是在ASP.NET MVC和Core中呈现部分视图的方法。HTML.Partial以MvcHtmlString的形式返回HTML内容，允许进一步操作，而HTML.RenderPartial直接写入响应流以提高效率。另一方面，HTML.Action和HTML.RenderAction调用子操作方法。HTML.Action返回一个MvcHtmlString，这对于捕获和操作输出很有用，而HTML.RenderAction直接写入响应流。选择取决于您捕获输出和性能要求的需要。对于直接渲染，HTML.RenderPartial和HTML.RenderAction更高效，而HTML.Partial和HTMLL.Action提供了更好的控制和灵活性。

When working with partial views and child actions in ASP.NET MVC and Core, it's essential to understand the differences between HTML.Partial, HTML.RenderPartial, HTML.Action, and HTML.RenderAction to make an informed choice based on your specific requirements.

在ASP.NET MVC和Core中使用分部视图和子操作时，必须了解HTML.Partial、HTMLRenderPartial、HTMLAction和HTMLL.RenderAction之间的差异，以便根据您的特定要求做出明智的选择。

1. HTML.Partial:

   
   
   
   
   • Return Type: MvcHtmlString
   
   
   • Purpose: Renders a partial view with content control.
   
   
   • Recommended Use Cases: Choose HTML.Partial when you need to capture and manipulate the output of a partial view before rendering it. This method provides you with control and flexibility over the rendered content. For example:
     

     @Html.Partial("_UserProfile", user)
     

     
     
   
   
   
   



2. HTML.RenderPartial:

   
   
   
   
   • Return Type: Writes to Response
   
   
   • Purpose: Renders a partial view efficiently.
   
   
   • Recommended Use Cases: Consider using HTML.RenderPartial when performance is a primary concern, and you don't require further manipulation of the output. This method efficiently renders a partial view without the need for additional control. For example:
     

     @Html.RenderPartial("_Sidebar")
     

     
     
   
   
   
   



3. HTML.Action:

   
   
   
   
   • Return Type: MvcHtmlString
   
   
   • Purpose: Invokes and captures the output of child action methods.
   
   
   • Recommended Use Cases: Utilize HTML.Action when you want to invoke a child action method and capture its output for further manipulation. This method allows you to control and modify the child action's output. For example:
     

     @Html.Action("RecentPosts", "Blog")
     

     
     
   
   
   
   



4. HTML.RenderAction:

   
   
   
   
   • Return Type: Writes to Response
   
   
   • Purpose: Invokes and renders child actions efficiently.
   
   
   • Recommended Use Cases: If you prioritize rendering efficiency for child actions and do not need to manipulate the output, choose HTML.RenderAction. It efficiently renders child actions without the need for additional control. For example:
     

     @Html.RenderAction("FeaturedItems", "Store")
     

     
     
   
   
   
   

The choice between these methods ultimately depends on your specific application needs. If you need control and flexibility over the output, opt for HTML.Partial or HTML.Action. If rendering efficiency is crucial and no further manipulation is required, consider HTML.RenderPartial or HTML.RenderAction.

这些方法之间的选择最终取决于您的特定应用程序需求。如果您需要对输出进行控制和灵活性，请选择HTML。Partial或HTML。操作。如果渲染效率至关重要并且不需要进一步的操作，请考虑HTML.RenderPartial或HTML.RenderAction。
