Wkhtmtopdf -- convert high-resolution HTML to PDF (3)

I browsed a lot of instances and couldn't find a combination of these two requirements, because I could not save HTML as PDF but throw the stream at the same time, let's make a contribution ~~

Next we will select a web page to print, save as PDF, and implement stream throw and save. Suppose we choose"Http://www.cnblogs.com/ITGirl00/"

Page example:

  string fileName = Guid.NewGuid().ToString();

            string outputPath = Server.MapPath("output");

String savepath = string. Format (outputPath + "\" + fileName + ". pdf"); // save

            string url = "http://www.cnblogs.com/ITGirl00/";

            try

            {

                if (!string.IsNullOrEmpty(url) || !string.IsNullOrEmpty(savepath))

                {

                    Process p = new Process();

                    string resource = HttpContext.Current.Server.MapPath("resoure");

                    string dllstr = string.Format(resource + "\\wkhtmltopdf.exe");

                    if (System.IO.File.Exists(dllstr))

                    {

                        p.StartInfo.FileName = dllstr;

                        p.StartInfo.Arguments = " \"" + url + "\"  \"" + savepath + "\"";

                        p.StartInfo.UseShellExecute = false;

                        p.StartInfo.RedirectStandardInput = true;

                        p.StartInfo.RedirectStandardOutput = true;

                        p.StartInfo.RedirectStandardError = true;

                        p.StartInfo.CreateNoWindow = true;

                        p.Start();

                        p.WaitForExit();

                        try

                        {

                            FileStream fs = new FileStream(savepath, FileMode.Open);

                            byte[] file = new byte[fs.Length];

                            fs.Read(file, 0, file.Length);

                            fs.Close();

                            Response.Clear();

Response. AddHeader ("content-disposition", "attachment; filename =" + fileName + ". pdf"); // encode

                            Response.ContentType = "application/octet-stream";

                            Response.BinaryWrite(file);

                        }

                        catch (Exception ee)

                        {

                            throw new Exception(ee.ToString());

                        }

                    }

                }

            }

            catch (Exception ex)

            {

                throw new Exception(ex.ToString());

            }
