问题描述 投票：0回答：2

我已经使用html模板创建了pdf文件生成。但是在h4标签上生成pdf背景色并且颜色也未设置后，建议我

我已经尝试在html中设置背景颜色和表格适当的边框颜色来内联css，但是在生成pdf之后，此css无法应用它

控制器：-

public void abcd()
        {
            try
            {
                string abc = Request.QueryString["abc"];
                string strFileName = abc;
                string strFileExtension = ".pdf";
                string strContentType = FileManager.FileContentType_application_msexcel;
                string strExportData = string.Empty;
                Document pdfDoc = new Document(PageSize.A4, 43f, 50f, 5f, 50f);
                HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
                var output = new MemoryStream();
                StringWriter sw = new StringWriter();
                HtmlTextWriter htw = new HtmlTextWriter(sw);
                StringReader sr;
                sr = new StringReader(Convert.ToString(ExportData.abcUserDetails(abc)));
                PdfWriter.GetInstance(pdfDoc, output);
                pdfDoc.Open();
                htmlparser.Parse(sr);
                pdfDoc.Close();
                strFileName = strFileName.Replace(" - ", "-").Replace(" ", "-").Replace("--", "-");
                Response.ClearContent();
                Response.Buffer = true;
                Response.AddHeader("content-disposition", string.Format("attachment; filename={0}{1}", strFileName, strFileExtension));
                Response.ContentType = strContentType;
                Response.Charset = "";
                Response.BinaryWrite(output.ToArray());
                Response.Flush();
                Response.End();
            }
            catch (Exception ex)
            {
                Settings.exceptionLog.Publish(ex);

            }
        }

型号：-

public static string abcUserDetails(string abc)
        {
            string strHtmlBody = (new WebClient()).DownloadString(HttpContext.Current.Server.MapPath("~/Templates/abcUserDetails.html"));
            string DomainURL = Settings.GetSettingsKeyValue("DomainURL");
            IDictionary<string, string> objData = new Dictionary<string, string>();
            dynamic dtUser = User.GetuserDetails(abc);

            foreach (dynamic m in dtUser)
            {

                objData.Add("User.Name", Convert.ToString(m["Name"]));
                objData.Add("User.RegNo", Convert.ToString(m["RegNo"]));
                objData.Add("User.Gender", Convert.ToString(m["Gender"]));
                objData.Add("User.EmailId", Convert.ToString(m["EmailId"]));
                objData.Add("User.Address", Convert.ToString(m["VLEAddress"]));

            }
            string strValue = string.Empty;
            foreach (KeyValuePair<string, string> data in objData)
            {
                strValue = HttpUtility.HtmlEncode(data.Value);
                strHtmlBody = strHtmlBody.Replace(string.Format("%{0}%", data.Key), strValue);
            }
            return strHtmlBody;
        }

html模板：-

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta charset="utf-8" />
    <link href="../css/custom/style.css" rel="stylesheet" />
    <title></title>

</head>
<body style="font-family:Arial;font-size:7.5px;vertical-align:top!important;">
    <h4 style="background-color:#d48d88;text-transform: uppercase;font-weight:bold;width:100%;">
        User Details
    </h4>
    <table border="1" style="color:#000000;border-color:#6f6f6f;border-style: ridge;">
        <tr>
            <td valign="top" style="font-weight:bold;">
                <b>Name</b>
            </td>
            <td valign="top">
                %User.Name%
            </td>
            <td valign="top" style="font-weight:bold;">
                <b>Mobile number</b>
            </td>
            <td valign="top">
                %User.Mobile%
            </td>
            <td valign="top" style="font-weight:bold;">
                <b>Email Id</b>
            </td>
            <td valign="top">
                %User.Email%
            </td>

        </tr>
    </table>
 </body>
</html>

预期输出：-enter image description here

默认情况下，HTML到PDF转换器将为“屏幕”呈现HTML文档，但是当将另一种媒体类型分配给HtmlToPdf.MediaType属性时，可以更改此属性。

例如，当此属性设置为'print'时，呈现HTML时将使用'@media print'规则定义的CSS属性，而不是'@media screen'规则定义的CSS属性。] >

 p { 
      font-family: Verdana; 
      font-size: 14px; 
      font-style: italic; 
      color: Green; 

 } 

 @media print { 
    p { 
        border-style: dashed;
    } 
 }
