Question

我正在尝试使用ITextSharp将文本添加到现有的pdf文件中。我完全不知道如何解决它。这是我到目前为止所尝试的。我想将wordDocContents附加到pdf文件中。我想在pdf文件的开头附加文本，因为pdf文件是空的。

using System;
using System.Web;
using System.Web.UI;
using TikaOnDotNet.TextExtraction;
using iTextSharp.text;
using iTextSharp.text.pdf;
using System.IO;

namespace Project    
{
    public partial class Default : System.Web.UI.Page
    {
        public void button1Clicked(object sender, EventArgs args)
        {
            button1.Text = "You clicked me";    
            var textExtractor = new TextExtractor();
            var wordDocContents = textExtractor.Extract("t.csv");
            Console.WriteLine(wordDocContents);
            Console.ReadLine();
            generatepdffile();
        }

        protected void generatepdffile()
        {   
            Document doc = new Document();
            PdfWriter.GetInstance(doc, new FileStream(Server.MapPath("file1.pdf"), FileMode.Create));
        }
    }
}

＆＃39; wordDocContents＆＃39;中的内容如下。我的目标是将内容按照下面打印的方式附加到pdf文件中。

ACCOUNT_NUMBER,CUSTOMER_NAMES,VALUE_DATE,BOOKING_DATE,TRANSACTION,ACCOUNT_TYPE,BALANCE_TYPE,REFERENCE,MONEY.OUT,MONEY.IN,RUNNING.BALANCE,BRANCH,EMAIL,ACTUAL.BALANCE,AVAILABLE.BALANCE
1000000001,TEST,,2847899,KES,Account,,,10/10/2016,9/11/2016,15181800,UPPER HILL BRANCH,another@yahoo.com,5403.75,5403.75,

以上问题不是建议的问题的重复，请看下面的链接。输出pdf的格式与链接中的格式完全不同。 https://postimg.org/image/tul7vxvrh/

您可能需要使用提取的文本向pdf添加至少一个段落。

可能的helper可能是

private void AddParagraph(Document doc, int alignment, iTextSharp.text.Font font, iTextSharp.text.IElement content) 
{ 
   Paragraph paragraph = new Paragraph(); 
   paragraph.SetLeading(0f, 1.2f); 
   paragraph.Alignment = alignment; 
   paragraph.Font = font; 
   paragraph.Add(content);
   doc.Add(paragraph); 
}

草拟使用的示例

      private Font _largeFont = new Font(Font.FontFamily.HELVETICA, 18, Font.BOLD, BaseColor.BLACK); 
      void generatepdffile(string content)

          {
            Document doc = new Document();
            PdfWriter.GetInstance(doc, new FileStream(Server.MapPath("file1.pdf"), FileMode.Create));
            doc.Open(); 
            AddParagraph(doc, iTextSharp.text.Element.ALIGN_CENTER, _largeFont, new Chunk(content));
            doc.Close();

          }

从你的

之类的东西中调用

generatepdffile(wordDocContents.Text);

创建表

基本上，您应该从csv字符串拆分

创建表

    PdfPTable table = new PdfPTable(colNum);
    foreach (string line in content.Split('\n'))
    {
        foreach (string cellstr in line.Split(','))
        {
            PdfPCell cell = new PdfPCell(new Phrase(cellstr));
            table.AddCell(cell);
        }
    }
    AddParagraph(doc, iTextSharp.text.Element.ALIGN_CENTER, _largeFont, table);

使用c＃中的ITextSharp将文本添加到现有的pdf文件中？
