Question

我想用我的所有表格生成PDF，我在谷歌上搜索，我发现上面的代码并且工作但是对于o图像和一些文本：

Imports System.Web
Imports System.Web.UI
Imports System.Data
Imports System.IO
Imports iTextSharp.text
Imports iTextSharp.text.pdf
Imports iTextSharp.text.html.simpleparser
Partial Class VBCode
    Inherits System.Web.UI.Page
    Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
    End Sub


    Public Overrides Sub VerifyRenderingInServerForm(control As Control)
        ' Verifies that the control is rendered 

    End Sub
    Protected Sub btnPDF_Click(sender As Object, e As EventArgs)
        Response.ContentType = "application/pdf"
        Response.AddHeader("content-disposition", "attachment;filename=UserDetails.pdf")
        Response.Cache.SetCacheability(HttpCacheability.NoCache)
        Dim sw As New StringWriter()
        Dim hw As New HtmlTextWriter(sw)
        Me.Page.RenderControl(hw)
        Dim sr As New StringReader(sw.ToString())
        Dim pdfDoc As New Document(PageSize.A4, 10.0F, 10.0F, 100.0F, 0.0F)
        Dim htmlparser As New HTMLWorker(pdfDoc)
        PdfWriter.GetInstance(pdfDoc, Response.OutputStream)
        pdfDoc.Open()
        htmlparser.Parse(sr)
        pdfDoc.Close()
        Response.Write(pdfDoc)
        Response.[End]()
    End Sub
End Class

这是包含代码的页面，在设计模式下是：

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="VBCode.aspx.vb" Inherits="VBCode" EnableEventValidation="false" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div><img src="https://lh5.googleusercontent.com/_B28NJpJ61hA/TdgnS7lh7mI/AAAAAAAAAi4/oLTicIRgEIw/FinalLogo.png" /></div>
<div><b>Export Webpage with images to pdf using itextsharp dll</b>
<br />

</div><br />
<div>
</div>
<asp:Button ID="btnPDF" runat="server" Text="Export to PDF" OnClick="btnPDF_Click"/>
</form>
</body>
</html>

我想用我的asp桌子生成pdf以及我想要的但是不起作用，如果你有其他选择请帮助我....

如果我把我的代码与所有代码一起给我错误：

无效的URI：无法解析主机名。

在线：htmlparser.Parse（sr）

如何在vb.net中使用当前的pageweb生成PDF？
