Question

现在，我有一个带有html.actionLink的index.cshtml，它带有一个html表的预览，该html表将数据从表单中拉出以准备打印它。然后，当我单击链接时，它将转到带有HTML的PDFOnePage.cshtml的预览。然后有一个按钮可以将其转到abcpdf方法进行打印。我想将两种动作都从index.cshtml转移到一个步骤。

这是我的index.cshtml的一部分，带有链接：

   <td>
            @Html.ActionLink("Edit", "Edit", new { id = item.ID }) |

            @Html.ActionLink("PDF", "PDFOnePage", new { id = item.ID }) 
   </td>

然后，当我单击PDF链接时，它会在打印之前显示html。

PDFOnePage.cshtml看起来像这样：

   <table frame="box" style="width:100%; border-collapse:separate">
        <tr>
            <td colspan="3"> <b>BlahBlahBlahLotsOfStuff</b></td>
        </tr>
   </table>


<button>
    <a href="@Url.Action("HmtltoPDF2","Applicant")">Export PDF</a>
   </button>

因此，当我们单击该按钮时，它将显示PDF，而当我执行ctrl-p时，它将显示打印gui。

该按钮访问我的ApplicantController.cs方法：

public FileStreamResult HmtltoPDF2()
        {
            //getting the url to convert to pdf
            String PreviousPage = System.Web.HttpContext.Current.Request.UrlReferrer.AbsoluteUri;


            //abcpdf was annoying for not accepting the Url directly 
            //so just make a string variable to assign the value of the url
            // DO NOT delete this and use PreviousPage directly
            //it will break the PDF Convertion.
            String HtmlToPDFConvertion = PreviousPage;
            MemoryStream m = new MemoryStream();
            Doc theDoc = new Doc();
            theDoc.MediaBox.String = "A4";
            theDoc.FontSize = 8;
            //theDoc.Rect.Inset(114, 162);
            theDoc.Rect.Inset(15, 1);

            theDoc.HtmlOptions.Engine = EngineType.Chrome;
            theDoc.HtmlOptions.UseScript = true; // enable JavaScript
            theDoc.HtmlOptions.Media = MediaType.Print; // Or Screen for a more screen oriented output
            theDoc.HtmlOptions.InitialWidth = 800; // In case we have a responsive site which is non-specific on good widths
                                                   //theDoc.HtmlOptions.RepaintDelay = 500; // Only required if you have AJAX or animated content such as graphs
                                                   //theDoc.HtmlOptions.IgnoreCertificateErrors = false; // Disabled for ease of debugging
                                                   //theDoc.HtmlOptions.FireShield.Policy = XHtmlFireShield.Enforcement.Deny; // Disabled for ease of debugging


            theDoc.Page = theDoc.AddPage();
            int theID;

            theID = theDoc.AddImageUrl(HtmlToPDFConvertion);

            while (true)
            {
                theDoc.FrameRect(); // add a black border
                if (!theDoc.Chainable(theID))
                    break;
                theDoc.Page = theDoc.AddPage();
                theID = theDoc.AddImageToChain(theID);
            }

            for (int i = 1; i <= theDoc.PageCount; i++)
            {
                theDoc.PageNumber = i;
                theDoc.Flatten();
            }
            theDoc.Save(Server.MapPath(Path));




            byte[] theData = theDoc.GetData();
            Response.Clear();
            Response.ContentType = "application/pdf";
            Response.AddHeader("content-disposition", "inline; filename=MyPDF.PDF");
            Response.AddHeader("content-length", theData.Length.ToString());
            Response.BinaryWrite(theData);
            Response.End();

            return File(m, "application/pdf", "test.pdf");
            //theDoc.Clear();
        }

这都是步骤的示意图：

如何摆脱在打印前两次查看PDF / html的中间步骤？就像将html.actionLink（PDF）和href Url.Action htmltoPDF2放在一起一样？我不想打印带有页面内容或滚动条的按钮。

我在这类事情上没有很多经验，因此我不确定要用谷歌搜索如何将它们整合到一个步骤中。我从一个不在这里的人那里继承了此网页。

如何一步完成两个动作
