HTML至PDF CSharp

从URL转换html到pdf.cs

WebRequest req = WebRequest.Create(@"https://docs.oracle.com/javase/tutorial/networking/urls/readingURL.html");
// 将网页放入流中
using (Stream stream = req.GetResponse().GetResponseStream())
{
	// 初始化HTML加载选项
	HtmlLoadOptions htmloptions = new HtmlLoadOptions("https://docs.oracle.com/");
	// 将流加载到Document对象中
	Document pdfDocument = new Document(stream, htmloptions);
	// 将输出另存为PDF格式
	pdfDocument.Save("HTML-to-PDF.pdf");
}

将html转换为pdf.cs

// 创建HTML加载选项
HtmlLoadOptions htmloptions = new HtmlLoadOptions();
// 载入HTML档案
Document doc = new Document("HTML-Document.html", htmloptions);
// 将HTML文件转换为PDF
doc.Save("HTML-to-PDF.pdf");

用加密将html转换为pdf.cs

// 创建HTML加载选项
HtmlLoadOptions htmloptions = new HtmlLoadOptions();
// 载入HTML档案
Document doc = new Document("HTML-Document.html", htmloptions);
// 设置加密参数
doc.Encrypt("userpassword", "ownerPassword", Permissions.ModifyContent, CryptoAlgorithm.AESx256);
// 将HTML文件转换为PDF
doc.Save("HTML-to-PDF.pdf");
