創建PDF文件？

Question

我看着iTextSharp和SharpPDF和Report.Net以及PDFSharp。

沒有這些開源項目具有良好的文檔或不符合2012年VS工作

有沒有人有一個推薦的解決方案或能告訴我的文檔？

我的僱主阻止了很多網站，雖然Google沒有被封鎖，但一些結果是。

我打算用C＃與WinForms和獲得我的數據從Access數據庫

嘗試this example：

using iTextSharp.text; 
// Set up the fonts to be used on the pages 
private Font _largeFont = new Font(Font.FontFamily.HELVETICA, 18, Font.BOLD, BaseColor.BLACK);

private Font _smallFont = new Font(Font.FontFamily.HELVETICA, 10, Font.NORMAL, BaseColor.BLACK); 
public void Build() 
{ 
    iTextSharp.text.Document doc = null; 
    try 
    { 
     // Initialize the PDF document 
     doc = new Document(); 
     iTextSharp.text.pdf.PdfWriter writer = iTextSharp.text.pdf.PdfWriter.GetInstance(doc,

       System.IO.FileMode.Create)); 
     // Set margins and page size for the document 
     doc.SetMargins(50, 50, 50, 50); 
     // There are a huge number of possible page sizes, including such sizes as 
     // EXECUTIVE, LEGAL, LETTER_LANDSCAPE, and NOTE 
     doc.SetPageSize(new iTextSharp.text.Rectangle(iTextSharp.text.PageSize.LETTER.Width, 
      iTextSharp.text.PageSize.LETTER.Height)); 
     // Add metadata to the document. This information is visible when viewing the

     this.AddPageWithBasicFormatting(doc);

     this.AddPageWithBulletList(doc); 
     this.AddPageWithExternalLinks(doc); 
     this.AddPageWithImage(doc, System.IO.Directory.GetCurrentDirectory() + "\\FinalGraph.jpg");

你可以隨時創建一個HTML頁面，然後使用wkhtmltopdf將其轉換成PDF格式。這有利於您不必使用iText等庫來構建PDF。您只需創建一個文本文件（html），然後將其傳遞給wkhtmltopdf可執行文件。
