iTextSharp的生成PDF文件会保存对话框关闭时 [英] iTextSharp-generated PDFs cause save dialog when closing

问题描述

我使用iTextSharp的生成PDF文档，并把它们保存到磁盘是这样的：

 文档的文档=新的文件（PageSize.LETTER，50，50，80，50）;
        的FileStream FS =新的FileStream（鲁塔，FileMode.OpenOrCreate，FileAccess.ReadWrite，FileShare.ReadWrite）;
        PdfWriter PDFWriter = PdfWriter.GetInstance（文件，FS）;        EsquemaFormato PageEventHandler =新EsquemaFormato（）;
        PageEventHandler.Title = TitleMiddle;
        PageEventHandler.TitleHeaderFont = FontFactory.GetFont（BaseFont.HELVETICA，12，Font.NORMAL）;
        PageEventHandler.TitleRightHeaderFont = FontFactory.GetFont（BaseFont.HELVETICA，9，Font.NORMAL）;
        PageEventHandler.HeaderLeft =农布雷
        PageEventHandler.HeaderRight = TitleRight;
        PageEventHandler.RutaImagen = RutaImagen;
        PageEventHandler.Cuerpo = Cuerpo;
        PDFWriter.PageEvent = PageEventHandler;        document.Open（）;
        document.Close（）;

我打开我刚刚创建的PDF文件，但是当我尝试关闭它会导致一个要不要救？出现对话框。这不与不与iTextSharp的生成的PDF发生

我在想什么？我见过使用响应解决方案，但我不使用它。
先谢谢了。

编辑：
按照布鲁诺的链接，我发现这个职位： iTextSharp的+的FileStream =损坏的PDF文件

这是没有的伎俩！
这是我的工作code现在：

 公共无效CreatePDF（字符串TitleMiddle，串鲁塔，串RutaImagen，串TitleRight，串Cuerpo）
    {
        使用（MemoryStream的毫秒=新的MemoryStream（））
        {
            文档的文档=新的文件（PageSize.LETTER，50，50，80，50）;
            PdfWriter PDFWriter = PdfWriter.GetInstance（文件，MS）;            EsquemaFormato PageEventHandler =新EsquemaFormato（）;
            PageEventHandler.Title = TitleMiddle;
            PageEventHandler.TitleHeaderFont = FontFactory.GetFont（BaseFont.HELVETICA，12，Font.NORMAL）;
            PageEventHandler.TitleRightHeaderFont = FontFactory.GetFont（BaseFont.HELVETICA，9，Font.NORMAL）;
            PageEventHandler.HeaderLeft =农布雷
            PageEventHandler.HeaderRight = TitleRight;
            PageEventHandler.RutaImagen = RutaImagen;
            PageEventHandler.Cuerpo = Cuerpo;
            PDFWriter.PageEvent = PageEventHandler;            document.Open（）;
            document.Close（）;
            字节[] =内容ms.ToArray（）;
            使用（的FileStream FS = File.Create（鲁塔））
            {
                fs.Write（含量，0，（int）的content.Length）;
            }
        }
    }
 

解决方案

你有没有尝试过没有FileAccess.ReadWrite，FileShare.ReadWrite属性？

我创建PDF的使用iTextSharp的日常生活，还从来没碰到了这个问题 - 你的code和矿山之间的主要区别是我不具备这些。

我怀疑文件共享离开文档有所开放，等着别人来完成与保存关闭它？

I am using iTextSharp to generate PDF documents, and save them to disk like this:

        Document document = new Document(PageSize.LETTER, 50, 50, 80, 50);
        FileStream fs = new FileStream(Ruta, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.ReadWrite);
        PdfWriter PDFWriter = PdfWriter.GetInstance(document, fs);

        EsquemaFormato PageEventHandler = new EsquemaFormato();
        PageEventHandler.Title = TitleMiddle;
        PageEventHandler.TitleHeaderFont = FontFactory.GetFont(BaseFont.HELVETICA, 12, Font.NORMAL);
        PageEventHandler.TitleRightHeaderFont = FontFactory.GetFont(BaseFont.HELVETICA, 9, Font.NORMAL);
        PageEventHandler.HeaderLeft = "Nombre";
        PageEventHandler.HeaderRight = TitleRight;
        PageEventHandler.RutaImagen = RutaImagen;
        PageEventHandler.Cuerpo = Cuerpo;
        PDFWriter.PageEvent = PageEventHandler;

        document.Open();
        document.Close();

Based on http://www.mazsoft.com/blog/post/2008/04/30/Code-sample-for-using-iTextSharp-PDF-library.aspx

I open any PDF file I just created, but when I try to close it causes a "Do you want to Save?" dialog to appear. This does not happen with PDFs that are not generated with iTextSharp.

What am I missing? I've seen solutions using Response but I don´t use it. Thanks in advance.

Update: Here is a sample http://dl.dropbox.com/u/4582874/test.pdf

EDIT: By following Bruno's link I found this post: iTextSharp + FileStream = Corrupt PDF file

That did the trick! Here is my working code now:

    public void CreatePDF(string TitleMiddle, string Ruta, string RutaImagen, string TitleRight, string Cuerpo)
    {
        using (MemoryStream ms = new MemoryStream())
        {
            Document document = new Document(PageSize.LETTER, 50, 50, 80, 50);
            PdfWriter PDFWriter = PdfWriter.GetInstance(document, ms);

            EsquemaFormato PageEventHandler = new EsquemaFormato();
            PageEventHandler.Title = TitleMiddle;
            PageEventHandler.TitleHeaderFont = FontFactory.GetFont(BaseFont.HELVETICA, 12, Font.NORMAL);
            PageEventHandler.TitleRightHeaderFont = FontFactory.GetFont(BaseFont.HELVETICA, 9, Font.NORMAL);
            PageEventHandler.HeaderLeft = "Nombre";
            PageEventHandler.HeaderRight = TitleRight;
            PageEventHandler.RutaImagen = RutaImagen;
            PageEventHandler.Cuerpo = Cuerpo;
            PDFWriter.PageEvent = PageEventHandler;

            document.Open();
            document.Close();
            byte[] content = ms.ToArray();
            using (FileStream fs = File.Create(Ruta))
            {
                fs.Write(content, 0, (int)content.Length);
            }
        }
    }

解决方案

Have you tried it without the FileAccess.ReadWrite, FileShare.ReadWrite properties?

I create PDF's using itextSharp everyday and have never ran into this issue - main difference between your code and mine is i don't have these.

I suspect the FileShare is leaving the document somewhat open, waiting for someone to finalise closing it with a save?
