來自預定義模板的多頁PDF文檔

我需要使用一些預定義的公司模板以PDF生成發票報告。我能夠創建/生成使用iTextSharp的PDF報告單頁。來自預定義模板的多頁PDF文檔

問題：發票聲明跨越多頁時出現問題。我無法將報告（發票聲明）擴展到下一頁（第2頁）。如果所有數據都不能放在一個頁面上，它應該寫在第二頁上，同時仍然使用公司模板。

模板存在於以下路徑：

HostingEnvironment.MapPath("~/Content/InvoiceTemplate/invoiceTemplate.pdf")

我使用iTextSharp的庫來創建文檔。以下是用於生成PDF的代碼：

public class pdfStatementController : Controller { 

     Models.DYNAMICS_EXTEntities _db = new Models.DYNAMICS_EXTEntities(); 

     // 
     // GET: /pdfStatement/ 


     public ActionResult SendPdfStatement(string InvoiceNumber) { 
      try { 
       InvoiceNumber = InvoiceNumber.Trim(); 

       ObjectParameter[] parameters = new ObjectParameter[1]; 
       parameters[0] = new ObjectParameter("InvoiceNumber", InvoiceNumber); 

       List<Models.Statement> statementList = new List<Models.Statement>(); 
       statementList = _db.ExecuteFunction<Models.Statement>("uspInvoiceStatement", parameters).ToList<Models.Statement>(); 
       pdfStatementController.WriteInTemplate(statementList); 

       return RedirectToAction("Invoice", "Invoice", new { id = statementList.FirstOrDefault().Customer_ID.ToString().Trim() }); 
      } catch (Exception e) { 
       return View("Error"); 
      } 
     } 

    public static void WriteInTemplate(List<Models.Statement> statementList) { 
     string invoiceNumber = statementList.FirstOrDefault().Invoice.ToString().Trim(); 
     string month = null; 
     string day = null; 
     string year = null; 

     PdfReader pdfReader = new PdfReader(
            HostingEnvironment.MapPath(
             "~/Content/InvoiceTemplate/invoiceTemplate.pdf")); 
     FileStream fileStream = new FileStream(
            HostingEnvironment.MapPath(
             "~/Content/reports/" + invoiceNumber + ".pdf"), 
             FileMode.Create); 
     PdfStamper pdfStamper = new PdfStamper(pdfReader, fileStream); 
     AcroFields pdfFields = pdfStamper.AcroFields; 

     pdfFields.SetField("BillToCompany", statementList.FirstOrDefault().BillToCompany.ToString().Trim().ToUpper()); 
     pdfFields.SetField("BillToContact", statementList.FirstOrDefault().BillToContact.ToString().Trim().ToUpper()); 
     pdfFields.SetField("CustomerId", statementList.FirstOrDefault().Customer_ID); 
     pdfFields.SetField("InvoiceNumber", statementList.FirstOrDefault().Invoice.ToString().Trim()); 
     pdfFields.SetField("JobNumber", statementList.FirstOrDefault().JobNumber.ToString().Trim()); 
     pdfFields.SetField("Caller", statementList.FirstOrDefault().Caller.ToString().Trim()); 

     pdfStamper.FormFlattening = true; // generate a flat PDF 
     pdfStamper.Close(); 
     pdfReader.Close(); 
    } 
}

你重新使用** **相同​​模板的每一頁，或者使用不同的** * *第二頁的模板？ – kuujinbo 2011-12-15 08:59:30

我爲每個頁面使用相同的模板。 – 14578446 2011-12-15 13:38:01

您的代碼看起來不錯，只缺少幾個中間步驟。

由於您使用相同的PDF模板爲每個頁面（當兩個或更多的頁面需要生成），而不是使用PdfStamper直接添加內容到Document，您使用PdfSmartCopy或PdfCopy對象。

PdfStamper仍然需要。但是，在這種情況下，它會用於創建一個充滿數據的內存（單頁）頁面，就像您在遍歷Models.Statement集合時一樣。

換句話說，​​3210作爲一個整體來維護您的語句，（總頁數）和PdfStamper被用作一個緩衝區，它將逐個頁面添加到您的PDF中。下面是一個簡單的工作示例HTTP hander（.ashx）：

<%@ WebHandler Language="C#" Class="copyFillTemplate" %> 
using System; 
using System.Collections.Generic; 
using System.IO; 
using System.Web; 
using iTextSharp.text; 
using iTextSharp.text.pdf; 

public class copyFillTemplate : IHttpHandler { 
    public void ProcessRequest (HttpContext context) { 
    HttpServerUtility Server = context.Server; 
    HttpResponse Response = context.Response; 
    Response.ContentType = "application/pdf"; 
// template used to test __this__ example; 
// replace with __your__ PDF template 
    string pdfTemplatePath = Server.MapPath(
     "~/app_data/template.pdf" 
    ); 
// this example's test data; replace with __your__ data collection 
    List<Statement> statementList = Statement.GetStatements(); 

// COPY FROM HERE 

    using (Document document = new Document()) { 
// PdfSmartCopy reduces PDF file size by reusing parts 
// of the PDF template, but uses more memory. you can 
// replace PdfSmartCopy with PdfCopy if memory is an issue 
     using (PdfSmartCopy copy = new PdfSmartCopy(
     document, Response.OutputStream) 
    ) 
     { 
     document.Open(); 
// used to test this example 
     int counter = 0; 
// generate one page per statement   
     foreach (Statement statment in statementList) { 
      ++counter; 
// replace this with your PDF form template   
      PdfReader reader = new PdfReader(pdfTemplatePath); 
      using (var ms = new MemoryStream()) { 
      using (PdfStamper stamper = new PdfStamper(reader, ms)) { 
       AcroFields form = stamper.AcroFields; 
// replace this with your field data for each page 
       form.SetField("title", counter.ToString()); 
       stamper.FormFlattening = true; 
      } 
      reader = new PdfReader(ms.ToArray()); 
// add one page at a time; assumes your template is only one page. 
// if your template is more than one page you will need to 
// call GetImportedPage() for each page in your template 
      copy.AddPage(copy.GetImportedPage(reader, 1)); 
      } 
     } 
     } 

// COPY TO HERE 

    } 
    } 
    public bool IsReusable { get { return false; } } 

    public class Statement { 
    public string FieldName, FieldValue; 
    public static List<Statement> GetStatements() { 
     List<Statement> s = new List<Statement>(); 
     for (int i = 0; i < 5; ++i) {s.Add(new Statement());} 
     return s; 
    } 
    } 
}

希望內聯評論幫助。你顯然需要刪除我用來測試示例代碼的部分代碼。

雖然最後一個答案是一個非常好的答案，並幫助我解決了我的問題，但我在這裏總結了這個問題。

問題：我在公司提供的模板中生成了多頁pdf文檔。需要生成發票聲明並通過Microsoft Outlook電子郵件客戶端將它們附加到電子郵件。
