1.实现代码把html转化为pdf主要是使用wkhtmltopdf.exe工具生成,在获取转化的地址,创建一个进程,把地址传递到进程参数中进行调用wkhtmltopdf.exe工具打印
2.代码片段//调用工具部分
/// <summary> /// 启动Wkhtmltopdf /// </summary> /// <param name="parms">启动参数</param> /// <returns></returns> public void StartWK(string parms, bool IsNoHead = true) { try { Process proc = new Process(); string resource = HttpContext.Current.Server.MapPath("~/Content/wkhtmltopdf/bin"); string dllstr = string.Format(resource + "\wkhtmltopdf.exe");
if (System.IO.File.Exists(dllstr)) { proc.StartInfo.FileName = dllstr; string strArguments = IsNoHead ? string.Empty : " --margin-top 20 --margin-bottom 20 --header-spacing 2 --footer-spacing 1 --footer-font-size 7 --footer-center "第[page]页/共[topage]页" "; strArguments += parms;
proc.StartInfo.Arguments = strArguments; proc.StartInfo.UseShellExecute = false; proc.StartInfo.RedirectStandardInput = true; proc.StartInfo.RedirectStandardOutput = true; proc.StartInfo.RedirectStandardError = true; proc.StartInfo.CreateNoWindow = true; proc.Start(); proc.WaitForExit(); } else { throw new Exception("wkhtmltopdf.exe启动异常!"); } } catch (Exception) { throw; } }
