渲染视图为一个字符串在ASP.NET MVC 2 [英] Rendering a view to a string in ASP.NET MVC 2

问题描述

我们需要渲染的的ActionResult 到字符串来的页面添加到我们的内部搜索引擎索引。我们选定了这个解决方案呈现给字符串

We need to render an ActionResult to a string to add pages to our internal search engine index. We settled on this solution to render to string.

我碰到的一个问题的ExecuteReuslt 通话用来处理视图。

I've run into a problem with the ExecuteResult call used to process the View.

var oldController = controllerContext.RouteData.Values["controller"];
controllerContext.RouteData.Values["controller"] = 
                  typeof(TController).Name.Replace("Controller", "");

viewResult.ExecuteResult(controllerContext); // this line breaks

我收到以下错误：

I receive the following error:

对象未设置为对象的实例错误。

我已经证实了的ViewResult 不为空，所以异常必须在的ExecuteReuslt 内部抛出。

I've confirmed viewResult is not null, so the exception has to be thrown internally in ExecuteResult.

什么，我们还缺？

推荐答案

我想它了。与该的ExecuteReuslt问题是工作不正常，是因为我没有嘲笑ControllerContext正常。我能够在这个SO职位描述嘲讽controllercontext来解决这一问题：

I figured it out. The issue with ExecuteResult wasn't working as expected was because I hadn't mocked the ControllerContext properly. I was able to solve the issue by mocking the controllercontext as described in this SO post:
