[qq_30152373]

代码如下 ，这个的问题是运行完毕之后PDF是有了但是PDF是空的，我要导出的是页面不是HTML样式！！！！！！！
string INPATH = "";
protected void Button1_Click(object sender, EventArgs e)
{
//INPATH = System.Web.HttpContext.Current.Server.MapPath("~/View/DSBG.aspx?ID=" + Request.QueryString["ID"] + "&YGXM='" + Server.UrlEncode(Session["YGXM"].ToString()) + "'");
////获取任务ID
int RWID = Convert.ToInt32(Request.QueryString["ID"]);
INPATH = Request.Url.Scheme + "://" + Request.Url.Authority + VirtualPathUtility.ToAbsolute("/View/PDF/DSBG.aspx?ID=" + Request.QueryString["ID"] + "&YGXM='" + Session["YGXM"].ToString() + "'");


string path = System.Web.HttpContext.Current.Server.MapPath("~/View/PDF");
if (!Directory.Exists(path))
Directory.CreateDirectory(path);

WebClient wc = new WebClient();
//从网址下载Html字串
wc.Encoding = System.Text.Encoding.UTF8;
string htmlText = getWebContent();
byte[] pdfFile = this.ConvertHtmlTextToPDF(htmlText);

string fileId = "/LWpdf.pdf";
System.IO.File.WriteAllBytes(path + fileId, pdfFile);

Response.ContentType = "application/pdf";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode("机动车辆保险车辆定损报告") + ".pdf");
Response.TransmitFile(Server.MapPath("~/View/PDF/LWpdf.pdf"));
Response.End();

LoadRWInfo(RWID);
}
