推荐答案

我不太确定你想要实现的目标是什么，但我可以告诉你它不是简单的壮举。 ASP.NET呈现HTML，当浏览器收到HTML时，将HTML呈现为GUI。如果我理解正确，你想要将服务器端生成的部分HTML转换为图像（png，gif，tiff或其他）。为了正确地执行此操作，渲染引擎直到该任务将需要整个信息，这些信息也可用于浏览器（CSS，javascript，doctype等）。

制作长篇故事简而言之，所述页面的完整HTML输出必须由该呈现引擎加载和解释，这将为服务页面添加相当多的延迟。我想不出任何人为什么会在他们的网络服务器上施加这种压力的任何理由，但是如果你能解释你真正想要的东西，也许我们可以引导你到另一个解决方案。

I'm not quite sure what you want to achieve by this as the ultimate goal, but I can tell you that it is not an easy feat. ASP.NET renders HTML which when received by the browser renders said HTML into a GUI. If I understand you correctly you want part of the HTML which is generated on the server side to be transformed into an image (png, gif, tiff or whatever). In order to do this correctly the rendering engine up to that task would need the whole information that would also be available to the browswer (CSS, javascript, doctype, etc.).
To make a long story short, the complete HTML output of said page would have to be loaded and interpreted by that rendering engine which would add quite some delay to serving your pages. I can't think of any good reason why anybody would put that kind of strain on their web server, but if you can explain what you are really after maybe we can guide you to another solution.
