Question

我需要根据从数据库获取的数据创建pdf文件。我必须从数据库中检索数据并将这些数据生成为pdf文件。

我想有指针（有用的信息）。

谢谢。

Answer 1

以下是您可以使用的list of Open Source PDF Librarie：

PDFjet示例

PDF pdf = new PDF();
Font f1 = new Font(pdf, "Helvetica");
Image image1 = new Image(pdf, "images/eu-map.png");
Image image2 = new Image(pdf, "images/fruit.jpg");
Image image3 = new Image(pdf, "images/mt-map.gif");
// Please note:
// All font and image objects must be created
// before the first page object.


Page page = new Page(pdf, A4.PORTRAIT);

text.SetText(
        "The map on the right is an embedded GIF image");
text.SetPosition(90.0, 800);
text.DrawOn(page);

image3.SetPosition(390, 630);
image3.ScaleBy(0.5);
image3.DrawOn(page);

pdf.wrap();
pdf.save("Example_03.pdf");

SharpPDF的例子

pdfDocument myDoc = new pdfDocument("TUTORIAL","ME");
pdfPage myPage = myDoc.addPage();
myPage.addText("Hello World!",200,450,predefinedFont.csHelvetica,20);
myDoc.createPDF(@"c:\test.pdf");
myPage = null;
myDoc = null;

Report.NET示例

Report report = new Report(new PdfFormatter());
FontDef fd = new FontDef(report, "Helvetica");
FontProp fp = new FontPropMM(fd, 25);
Page page = new Page(report);
page.AddCenteredMM(80, new RepString(fp, "Hello World!"));
RT.ViewPDF(report, "HelloWorld.pdf");

iTextSharp示例

Document document=new Document();
PdfWriter.getInstance(document,new FileOutputStream("hello.pdf"));
document.open();  
document.add(new Paragraph("Hello Pdf"));
document.close();

动态返回创建PDF文件

您可以使用Response.Write返回二进制数据，请参阅"How To Write Binary Data"

上的MSDN

以下是有关如何使用Response.WriteFile向用户提供PDF的示例：

//Set the appropriate ContentType.
Response.ContentType = "Application/pdf";
//Get the physical path to the file.
string FilePath = MapPath("acrobat.pdf");
//Write the file directly to the HTTP content output stream.
Response.WriteFile(FilePath);
Response.End();

Answer 2

您可以{/ 3}}使用

protected void btnExportPdf_Click(object sender, EventArgs e)
{
    Response.ContentType = "application/pdf";
    Response.AddHeader("content-disposition", "attachment;filename=BusinessUnit.pdf");
    Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
    StringWriter sw = new StringWriter();
    HtmlTextWriter hw = new HtmlTextWriter(sw);
    GridView grd = new GridView();
    grd.DataSource = yourdatatable.DefaultView//get data from DB in Datatable
    grd.DataBind();
    grd.RenderControl(hw);
    StringReader sr = new StringReader(sw.ToString());
    Document pdfDoc = new Document(PageSize.A2, 8f, 8f, 8f, 8f);
    HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
    PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
    pdfDoc.Open();
    htmlparser.Parse(sr);
    pdfDoc.Close();
    Response.Write(pdfDoc);
    Response.End();
}

阿西，

幸运的是，我最近一直在这条赛道上走下坡路。这里有一些帮助我的链接（与iTextSharp相关）：

http://www.codeproject.com/Articles/66948/Rendering-PDF-views-in-ASP-MVC-using-iTextSharp.aspx?msg=3800063#xx3800063xx

使用这个lib很好用，很容易使用。
