C# wkhtmltopdf 将html转pdf（详解）

https://www.cnblogs.com/louby/p/905198.html转自，看文章只放了代码看起来云里雾里的，在此做些解析

使用说明：

1.首先呢，得安装下软件，地址下面有链接，文件里有使用说明

2.代码里安装路径得改下，改成你安装的路径，或者把wkhtmltopdf.exe 文件放在网站bin目录下

3.设置下输出路径，转好的pdf得有地方存，代码里是放在了D盘，可以变动

4.就可以使用啦，直接调用HtmlToPdf(string url) url为要转的html路径。

一、转换程序代码如下：

 public string HtmlToPdf(string url)
        {
            bool success = true;
           // string dwbh = url.Split('?')[1].Split('=')[1];
            //CommonBllHelper.CreateUserDir(dwbh);
            //url = Request.Url.Host + "/html/" + url;
            string guid = DateTime.Now.ToString("yyyyMMddhhmmss");
            string pdfName =   "1.pdf";
            //string path = Server.MapPath("~/kehu/" + dwbh + "/pdf/") + pdfName;
            string path = "D:\" + pdfName;
            try
            {
                if (string.IsNullOrEmpty(url) || string.IsNullOrEmpty(path))
                    success = false;
　　　　　　　　　　//获取安装路径
                string str = Server.MapPath("~\bin\wkhtmltopdf.exe");
                Process p = System.Diagnostics.Process.Start(str, url+" "+path);
                p.WaitForExit();
                if (!System.IO.File.Exists(str))
                    success = false;
                if (System.IO.File.Exists(path))
                {
                    FileStream fs = new FileStream(path, FileMode.Open);
                    byte[] bytes = new byte[(int)fs.Length];
                    fs.Read(bytes, 0, bytes.Length);
                    fs.Close();
                    if (Request.UserAgent != null)
                    {
                        string userAgent = Request.UserAgent.ToUpper();
                        if (userAgent.IndexOf("FIREFOX", StringComparison.Ordinal) <= 0)
                        {
                            Response.AddHeader("Content-Disposition",
                                          "attachment;  filename=" + HttpUtility.UrlEncode(pdfName, Encoding.UTF8));
                        }
                        else
                        {
                            Response.AddHeader("Content-Disposition", "attachment;  filename=" + pdfName);
                        }
                    }
                    Response.ContentEncoding = Encoding.UTF8;
                    Response.ContentType = "application/octet-stream";
                    //通知浏览器下载文件而不是打开
                    Response.BinaryWrite(bytes);
                    Response.Flush();
                    Response.End();
                    fs.Close();
                    System.IO.File.Delete(path);
                }
                else
                {
                    Response.Write("文件未找到,可能已经被删除");
                    Response.Flush();
                    Response.End();
                }
            }
            catch (Exception ex)
            {
                success = false;
            }
            return "";
        }
