.NET使用DinkToPdf将HTML转成PDF的示例代码

0.介绍

C# .NET Core wrapper for wkhtmltopdf library that uses Webkit engine to convert HTML pages to PDF.

最近浏览文章的时候发现DinkToPdf框架，可以利用HTML转换成PDF，与我早期使用ITextSharp 框架构建PDF的方式不太一样。DinkToPdf直接将HTML转成PDF，HTML的构造直观且简单。这种方式可能可以成为不错的选择！
下面为大家简单介绍DinkToPdf的使用方式。

									</head>

									<body>

									<h4>Html文本</h4>

									</body>

									</html>

									var doc = new HtmlToPdfDocument()

									{

									 GlobalSettings = {

									  ColorMode = ColorMode.Color,

									  Orientation = Orientation.Landscape,

									  PaperSize = PaperKind.A4,

									 },

									 Objects = {

									  new ObjectSettings() {

									   PagesCount = true,

									   HtmlContent = htmlContent,

									   WebSettings = { DefaultEncoding = "utf-8" },

									   HeaderSettings = { FontSize = 9, Right = "Page [ page ] of [ toPage ]", Line = true },

									   FooterSettings = { FontSize = 9, Right = "Page [ page ] of [ toPage ]" }

									 Objects = {

									  new ObjectSettings()

									  {

									   Page = url,

									{

									 Directory.CreateDirectory("Files");

									}

									using (FileStream stream = new FileStream(@"Files\" + DateTime.UtcNow.Ticks.ToString() + ".pdf", FileMode.Create))

									{

									 stream.Write(pdf, 0, pdf.Length);

									}
