使用asp.net中的itextsharp将HTML文本转换为pdf文件时出错

Question

我使用以下代码将Editor(Ajax控件)中的内容转换为pdf,

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

using System.IO;
using iTextSharp.text.html.simpleparser;
using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.html;
/// <summary>
/// Summary description for pdfgeneration
/// </summary>
public class pdfgeneration
{
    public pdfgeneration()
    {
        //
        // TODO: Add constructor logic here
        //
    }

    public void pdfgenerator(String name1, AjaxControlToolkit.HTMLEditor.Editor Editor1)
    {

        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.ContentType = "application/pdf";
        // Create PDF document
        Document pdfDocument = new Document(PageSize.A4, 70, 55, 40, 25);

        PdfWriter wri = PdfWriter.GetInstance(pdfDocument, new FileStream("e://" +name1 + ".pdf", FileMode.Create));

        PdfWriter.GetInstance(pdfDocument, HttpContext.Current.Response.OutputStream);

        pdfDocument.Open();
        string htmlText = Editor1.Content;
        System.Collections.Generic.List<IElement> htmlarraylist = HTMLWorker.ParseToList(new StringReader(htmlText), null);

        for (int k = 0; k < htmlarraylist.Count; k++)
        {
            pdfDocument.Add((IElement)htmlarraylist[k]);
        }

        pdfDocument.Close();
        HttpContext.Current.Response.End();
    }


}

我最初在编辑器(Ajax控件)中对以下HTML文本进行了硬编码,

String editorcontent = "<br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>" +
                 "<br/>" + "<P align='center'><b>" + courtname + "</b></P>"
                + "<br/><P align='center'>(Before" + jname + "," + desname + ")"
                + "<br/>" + "<P align='right'><b><u>" + DropDownList1.SelectedItem + " no. " + TextBox1.Text + "/" + TextBox2.Text + "</u></b>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</P>"
                + "<br />"
  **//this table is the problem//**    + "<table><tr><td width='750px'><p align='left'>" + petitioner + "</p>" + "</td><td>" + "<p align='right'>" + "..Applicant" + "</p>" + "</td></tr>" + "<tr><td><p align='center'>" + "V/s" + "</p>" + "</td><td></td>" + "</tr>" + "<tr><td width='75px'><p align='left'>" + respondent + "</p>" + "</td><td>" + "<p align='right'>" + "..Respondent" + "</p>" + "</td></tr></table>"
                + "<br/><P align='center'><b><u>ORDER</u></b>";
            Editor1.Content = editorcontent;

如果我table从上面的代码中删除以下内容,而不是成功生成pdf.但是一旦我table在我的HTMl代码中包含它,我得到以下错误

如何解决我的问题.

Answer 1

iTextSharp的当前版本不不支持与"PX"指定的单元宽度.它确实支持百分比或数值,只有宽度单元宽度.

当你尝试对HTML内容进行硬编码时,两个地方都有'px':

1. <td width='750px'>
2. <td width='75px'>

删除'px',你会没事的.
