我是 Razor 引擎的新手，只是有一個(gè)關(guān)于在 ASP.NET MVC 中生成響應(yīng)的問(wèn)題首先我們知道視圖引擎的作用就是將對(duì)視圖的請(qǐng)求轉(zhuǎn)化為ViewEngineResult對(duì)象，而Razor視圖引擎實(shí)現(xiàn)了IViewEnginepublic interface IViewEngine{   ViewEngineResult FindView(ActionContext context, string viewName, bool isMainPage);   ViewEngineResult GetView(string executingFilePath, string viewPath, bool isMainPage);}在FindVieworGetView方法中，Razor 引擎返回一個(gè)ViewEngineResult對(duì)象：// pseudo code for simplificationif view_found    return ViewEngineResult.Found(viewName, new RazorView(...));實(shí)現(xiàn)為RazorView：IViewpublic class RazorView : IView{   public string Path { get; }   public virtual Task RenderAsync(ViewContext context);}函數(shù)RenderAsync似乎是產(chǎn)生響應(yīng)的人。但是 .cshtml 文件也會(huì)被 Razor 引擎編譯成 C# 類(lèi)，下面是生成 index.cshtml 的 C# 代碼的示例：public class ASPV_Views_Home_Index_cshtml : RazorPage<string[]> {   ...   public override async Task ExecuteAsync() {      ...//this method also seems to generate response   }}所以ExecuteAsync似乎也產(chǎn)生了反應(yīng)最后，如果我們查看ViewResult操作方法返回的對(duì)象，則ViewResult實(shí)現(xiàn)ActionResult(implements IActionResult) 為public class ViewResult : ActionResult{  ...  public override Task ExecuteResultAsync(ActionContext context); }ExecuteResultAsync似乎也產(chǎn)生了反應(yīng)。所以我們有三個(gè)候選人1-RazorView.RenderAsync()2-RazorPage.ExecuteAsync()3-ViewResult.ExecuteResultAsync()哪一個(gè)是真正產(chǎn)生響應(yīng)的？
