在MVC3剃须刀，我怎么一个动作内部渲染视图的HTML？ [英] In MVC3 Razor, how do I get the html of a rendered view inside an action?

问题描述

是否有人知道如何获得一个动作内部的视图的生成html？

它是这样的：

 公众的ActionResult DO（）
{
    VAR HTML =的RenderView（你好，模型）;
...
}
 

解决方案

我在使用I类名为 Utilities.Common 我的意见传递给客户端的静态方法作为JSON的属性的对象不断让我有必要给他们呈现为一个字符串。这里亚去：

 公共静态字符串RenderPartialViewToString（控制器控制器，字符串的viewName，对象模型）
{
    controller.ViewData.Model =模型;
    使用（StringWriter的SW =新的StringWriter（））
    {
        ViewEngineResult的ViewResult = ViewEngines.Engines.FindPartialView（controller.ControllerContext，的viewName）;
        ViewContext viewContext =新ViewContext（controller.ControllerContext，viewResult.View，controller.ViewData，controller.TempData，SW）;
        viewResult.View.Render（viewContext，SW）;        返回sw.ToString（）;
    }
}
 

这将为全面的意见，以及局部视图的工作，只是改变 ViewEngines.Engines.FindPartialView 到 ViewEngines.Engines.FindView 。

Does anybody know how to get the generated html of a view inside an action?

Is it something like this:

public ActionResult Do()
{
    var html = RenderView("hello", model);
...
}

解决方案

I use a static method in a class I called Utilities.Common I pass views back to the client as properties of JSON objects constantly so I had a need to render them to a string. Here ya go:

public static string RenderPartialViewToString(Controller controller, string viewName, object model)
{
    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.ToString();
    }
}

This will work for full views as well as partial views, just change ViewEngines.Engines.FindPartialView to ViewEngines.Engines.FindView.
