下午所有人,
有人建议我可以使用iTextSharp帮助我将网页转换为.PDF文件。我正在使用以下链接作为示例教程,但无法生成.pdf?
访问http://www.dotnetspark.com/kb/654-simple-way-to-create-pdf-document-using.aspx
我使用的是VB示例。我已经将iTextSharp.dll添加到我的项目中,并根据请求添加了名称空间。我只是创建了一个空白页面,并在页面上添加了一个按钮,使用下面的代码,我似乎不能获得这个来生成文件?
这是我的代码。
Imports iTextSharp.text
Imports iTextSharp.text.pdf
Partial Class pdf
Inherits System.Web.UI.Page
Protected Sub btnGeneratePDF_Click(ByVal sender As Object, ByVal e As EventArgs)
'Create Document class obejct and set its size to letter and give space left, right, Top, Bottom Margin
Dim doc As New Document(iTextSharp.text.PageSize.LETTER, 10, 10, 42, 35)
Try
Dim wri As PdfWriter = PdfWriter.GetInstance(doc, New FileStream("d:\myfolder\test.pdf", FileMode.Create))
'Open Document to write
doc.Open()
'Write some content
Dim paragraph As New Paragraph("This is my first line using Paragraph.")
Dim pharse As New Phrase("This is my second line using Pharse.")
Dim chunk As New Chunk(" This is my third line using Chunk.")
' Now add the above created text using different class object to our pdf document
doc.Add(paragraph)
doc.Add(pharse)
doc.Add(chunk)
Catch dex As DocumentException
'Handle document exception
Catch ioex As IOException
'Handle IO exception
Catch ex As Exception
'Handle Other Exception
Finally
'Close document
doc.Close()
End Try
End Sub结束类
这是按钮的代码...

</html>有没有人能帮我看看这个,让我知道哪里出错了?
问候贝蒂

我不确定这是否能解决所有问题,但至少你会错过按钮上的Click_Event。
<asp:Button ID="btnGeneratePDF" runat="server" Text="Generate .PDF" OnClick="btnGeneratePDF_Click" />(我看到你昨天问了这个问题:Button ClickEvent is not triggered有同样的问题,下次试着记住;-)
