推荐答案

没有鼠标移动和键盘在PDF文件中。 PDF文件是一份文件。 :-)



更严重的是，没有在ASP.NET中打开PDF文件这样的东西。 PDF文件可以在浏览器中打开，但这不是标准化的。 PDF不是W3标准的一部分。所以，这一切都取决于浏览器，通常在一些插件中实现，这个功能永远不会得到保证。没错，你绝不能假设PDF可以在浏览器中打开。面对没有任何PDF查看器的系统是完全可能的。唯一保证的可能性是将文档保存在文件中，这根本不是问题，因为任何人都可以保存并稍后查看。



但最重要的是事情是：如果真的有可能做你想做的事情，它将成为巨大的滥用和对大多数基本客户权利的不可接受的限制。你没有这种可能性是唯一的好处。当然，您可以使用这样的功能创建自己的浏览器插件，但是谁想要使用它？这与向被逮捕的一些人发表手铐广告有关。 :-)

There is no "mouse movement and keyboard" in a PDF file. PDF file is a document. :-)

More seriously, there is no such thing as "open PDF file in ASP.NET". PDF files can be opened in browser, but this is not standardized. PDF is not a part of W3 standards. So, it all depends on browser, usually implemented in some plug-ins and this feature is never guaranteed. That's right, you should never assume that PDF can be opened in a browser. It's quite possible to face a system without any PDF viewer at all. The only guaranteed possibility is to save a document in a file, which is not a problem at all, because anyone can save it and view later.

But the most important things is: if it was really possible to do what you want, it would became a huge abuse and unacceptable limitation of most basic customer's rights. It's only good that you don't have such possibility. Of course, you could create your own browser plug-in with such "feature", but who would like to use it? It would be the same as addressing to some people under arrest with advertizement of handcuffs. :-)
