如何使用asp.net将HTML页面构建的一部分转换为PDF

您可以尝试使用此工具，这对HTML到pdf的对话非常有用http://wkhtmltopdf.org/

这是将HTML字符串转换为PDF字节的代码。

public byte[] Convert(string source, string commandLocation)
        {
            Process p;
            ProcessStartInfo psi = new ProcessStartInfo();
            psi.FileName = commandLocation;
            psi.WorkingDirectory = @"D:\" ;// Path.GetDirectoryName(psi.FileName);

            // run the conversion utility
            psi.UseShellExecute = false;
            psi.CreateNoWindow = true;
            psi.RedirectStandardInput = true;
            psi.RedirectStandardOutput = true;
            psi.RedirectStandardError = true;

            // note: that we tell wkhtmltopdf to be quiet and not run scripts
            string args = "-q -n ";
            args += "--disable-smart-shrinking ";
            args += "";
            args += "--outline-depth 0 ";
            args += "--page-size A4 ";
            args += " - -";

            psi.Arguments = args;

            p = Process.Start(psi);

            try
            {
                using (StreamWriter stdin = p.StandardInput)
                {
                    stdin.AutoFlush = true;
                    stdin.Write(source);
                }

                //read output
                byte[] buffer = new byte[32768];
                byte[] file;
                using (var ms = new MemoryStream())
                {
                    while (true)
                    {
                        int read = p.StandardOutput.BaseStream.Read(buffer, 0, buffer.Length);
                        if (read <= 0)
                            break;
                        ms.Write(buffer, 0, read);
                    }
                    file = ms.ToArray();
                }

                p.StandardOutput.Close();
                // wait or exit
                p.WaitForExit(60000);

                // read the exit code, close process
                int returnCode = p.ExitCode;
                p.Close();

                if (returnCode == 0)
                    return file;
                else
                    LogManager.Log("Could not create PDF, returnCode:" + returnCode);
            }
            catch (Exception ex)
            {
                LogManager.Log("Could not create PDF", ex);
            }
            finally
            {
                p.Close();
                p.Dispose();
            }
            return null;
        }

这里的“源代码”是HTML代码，而commandLocation是wkhtmltopdf.exe的完整文件路径，您可以从上面的链接下载。该函数返回byte []，这是pdf文件，您可以将其保存在磁盘上，也可以通过编写Response.Write（byte）返回到浏览器；并更改MIMIE类型。
