我想通过将HTML内容传递给函数来生成PDF。我已经为此使用了iTextSharp,但它在遇到表和布局时表现不佳。
有没有更好的办法?

PDFmyURL最近也发布了一个。net组件,用于网页/ HTML到PDF的转换。它有一个非常友好的用户界面,例如:
PDFmyURL pdf = new PDFmyURL("yourlicensekey");
pdf.ConvertURL("http://www.example.com", Application.StartupPath + @"\example.pdf");

这取决于您的其他需求。
一个非常简单但不容易部署的解决方案是使用WebBrowser控件加载Html,然后使用Print方法打印到本地安装的PDF打印机。有一些免费的PDF打印机,WebBrowser控件是. net框架的一部分。
编辑: 如果你的Html是XHtml,你可以使用PDFizer来完成这项工作。
最好的工具,我发现和用于生成javascript和样式渲染视图或html页面的PDF是phantomJS。
下载带有rasterize.js函数的.exe文件,在示例文件夹的exe根目录下找到,并放入解决方案。
它甚至允许你下载文件在任何代码,而不打开该文件,它也允许下载文件时,风格和特别是jquery应用。
以下代码生成PDF文件:
public ActionResult DownloadHighChartHtml()
{
string serverPath = Server.MapPath("~/phantomjs/");
string filename = DateTime.Now.ToString("ddMMyyyy_hhmmss") + ".pdf";
string Url = "http://wwwabc.com";
new Thread(new ParameterizedThreadStart(x =>
{
ExecuteCommand(string.Format("cd {0} & E: & phantomjs rasterize.js {1} {2} \"A4\"", serverPath, Url, filename));
//E: is the drive for server.mappath
})).Start();
var filePath = Path.Combine(Server.MapPath("~/phantomjs/"), filename);
var stream = new MemoryStream();
byte[] bytes = DoWhile(filePath);
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=Image.pdf");
Response.OutputStream.Write(bytes, 0, bytes.Length);
Response.End();
return RedirectToAction("HighChart");
}
private void ExecuteCommand(string Command)
{
try
{
ProcessStartInfo ProcessInfo;
Process Process;
ProcessInfo = new ProcessStartInfo("cmd.exe", "/K " + Command);
ProcessInfo.CreateNoWindow = true;
ProcessInfo.UseShellExecute = false;
Process = Process.Start(ProcessInfo);
}
catch { }
}
private byte[] DoWhile(string filePath)
{
byte[] bytes = new byte[0];
bool fail = true;
while (fail)
{
try
{
using (FileStream file = new FileStream(filePath, FileMode.Open, FileAccess.Read))
{
bytes = new byte[file.Length];
file.Read(bytes, 0, (int)file.Length);
}
fail = false;
}
catch
{
Thread.Sleep(1000);
}
}
System.IO.File.Delete(filePath);
return bytes;
}

如果你想让用户在浏览器中下载渲染页面的pdf,那么最简单的解决方案是
window.print();
在客户端,它将提示用户保存当前页面的PDF。您还可以通过链接样式自定义pdf的外观
<link rel="stylesheet" type="text/css" href="print.css" media="print">
css在打印时应用于HTML。
限制
不能将文件存储在服务器端。 用户提示打印页面时,必须手动保存页面。 页必须在选项卡中呈现。
