iTextSharp無法在Winforms項目中運行

Question

環境

C＃2008 Express Edition，Windows Forms，iTextSharp 5.4.0。

我把iTextSharp.dll在我的項目bin文件夾，我添加了一個參考它在我的項目，我有命名空間using iTextSharp，iTextSharp.text和iTextSharp.text.pdf，我已經試過下面的代碼片段，但沒有創建並沒有錯誤消息。

這是第一個塊：

Document doc1 = new Document(); 
string path = "C:/Temp/Testing"; 
PdfWriter.GetInstance(doc1, new FileStream(path + "first.pdf", FileMode.Create)); 
doc1.Open(); 
doc1.Add(new Paragraph("Test")); 
doc1.Close(); 

，這裏是第二塊：

FileStream fs = new FileStream("C:\\Temp\\Testing" + "Test.pdf", FileMode.Create); 
Document doc = new Document(); 
PdfWriter writer = PdfWriter.GetInstance(doc, fs); 
doc.Open(); 
doc.Add(new Paragraph("Hello")); 
doc.Close(); 
writer.Close(); 
fs.Close();

這個例子打開一個對話框，用戶可以保存文件。用代碼轉換器將VB代碼轉換爲C＃。

Using ms As New System.IO.MemoryStream() 
Using doc As New iTextSharp.text.Document(iTextSharp.text.PageSize.A4) 
Using w As iTextSharp.text.pdf.PdfWriter = iTextSharp.text.pdf.PdfWriter.GetInstance(doc, ms) 

Dim FileName As String = "Name.pdf" 


Here create your document end close it 

Response.Clear() 
Response.ContentType = "application/octet-stream" 
Response.AddHeader("content-disposition", "attachment;filename= " & FileName) 
Response.Buffer = True 
Response.Clear() 
Dim bytes = ms.ToArray() 
Response.OutputStream.Write(bytes, 0, bytes.Length) 
Response.OutputStream.Flush() 


End Using 
End Using 
End Using
