从局部视图返回纯HTML

Question

如何在2个或更多JSON字段中返回HTML？

return Json(
new 
{
   Breadcrumbs = PartialView("Breadcrumbs/Breadcrumbs", model.Breadcrumbs),
   FolderDetail = PartialView("Detail/Folder", model.FolderDetail)
});

在这种情况下，我不会在result.BreadCrumbs和result.FolderDetail中获取HTML，而是获取JSON对象

PartialView是一个ActionResult，它告诉系统渲染局部视图而不是输出HTML。这是我目前用于在将字符串添加到JSON结果之前将其呈现给字符串的代码：

    public static string RenderPartialToString(this Controller controller, string viewName, object model)
    {
        if (string.IsNullOrEmpty(viewName))
            viewName = controller.ControllerContext.RouteData.GetRequiredString("action");

        controller.ViewData.Model = model;

        using (StringWriter sw = new StringWriter())
        {
            ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(controller.ControllerContext, viewName);
            ViewContext viewContext = new ViewContext(controller.ControllerContext, viewResult.View, controller.ViewData, controller.TempData, sw);
            viewResult.View.Render(viewContext, sw);

            return sw.GetStringBuilder().ToString();
        }
    }
