C# PDF Printing Library
提问by Adam Haile
Are there any free libraries that would "print" to a PDF without actually having to install a PDF printer on the system. I want something that can be completely self contained in my application. The reason I say I want it to "print" is that I've tried and tried to find a solution for directly converting from HTML with CSS to PDF, but it does't seem very possible. So I want to use the System.Windows.Forms.WebBrowser control to render the page first and then output that rendering to PDF. I just don't want the user to be required to install a PDFPrinter.
是否有任何免费库可以“打印”到 PDF，而实际上不必在系统上安装 PDF 打印机。我想要一些可以完全独立于我的应用程序的东西。我说我希望它“打印”的原因是我已经尝试并试图找到一种直接从带有 CSS 的 HTML 转换为 PDF 的解决方案，但这似乎不太可能。所以我想使用 System.Windows.Forms.WebBrowser 控件首先呈现页面，然后将该呈现结果输出为 PDF。我只是不希望用户被要求安装 PDFPrinter。

Does it have to be free? Last time I looked at ABCpdfit looked quite good, and claims to support css (here).
它必须是免费的吗？上次我看ABCpdf 时，它看起来相当不错，并声称支持 css（这里）。
HTMLDOCshould support css at some point, but last time I checked the css stuff was still in beta. And has been for "some time"; I've given up waiting... It isn't .NET, but you can use Processto invoke it.
HTMLDOC应该在某个时候支持 css，但上次我检查 css 的东西仍处于测试阶段。并且已经“有一段时间”了；我已经放弃等待...它不是 .NET，但您可以使用Process它来调用它。

http://www.html-to-pdf.net/- This isn't free but its preety cheap and effective. I am using it now to convert HTML with CSS to PDF. Essentially we display the page to the user and then with a click of a button they can download a PDF of the page.
