用wkhtmltopdf创建pdf并渲染javascript

我打电话来创建PDF如下：

public byte[] WKHtmlToPdf(string url)
    {
        var fileName = " - ";
        var wkhtmlDir = "C:Tempwkhtml";
        var wkhtml = "C:Tempwkhtmlwkhtmltopdf.exe";
        var p = new Process();

        p.StartInfo.CreateNoWindow = true;
        p.StartInfo.RedirectStandardOutput = true;
        p.StartInfo.RedirectStandardError = true;
        p.StartInfo.RedirectStandardInput = true;
        p.StartInfo.UseShellExecute = false;
        p.StartInfo.FileName = wkhtml;
        p.StartInfo.WorkingDirectory = wkhtmlDir;

        string switches = "";
        switches += "--print-media-type ";
        switches += "--margin-top 0mm --margin-bottom 0mm --margin-right 0mm --margin-left 0mm ";
        switches += "--page-size Letter ";
        p.StartInfo.Arguments = switches + " " + url + " " + fileName;
        p.Start();

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

                if (read <= 0)
                {
                    break;
                }
                ms.Write(buffer,read);
            }
            file = ms.ToArray();
        }

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

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

        return returnCode == 0 ? file : null;
    }

关于我如何抓住JavaScript图表的任何想法？也许.Net版本更合适,或者我必须将生成的页面保存到文件中,并将其传递到工具中.

谢谢.
