Question

单击时有一个按钮，将文本插入到pdf中的表单域中，并将填充的pdf保存到目录中。当我完成编辑pdf时，我想在浏览器中打开pdf，但Process.Start（）不起作用。是否有更好的方法在生成后立即显示pdf？这是按钮的代码：

protected void btnGenerateQuote_Click(object sender, EventArgs e)
{
    string address = txtAddress.Text;
    string company = txtCompany.Text;
    string outputFilePath = @"C:\Quotes\Quote-" + company + "-.pdf";
    PdfReader reader = null;
    try
    {
        reader = new PdfReader(@"C:\Quotes\Quote_Template.pdf");
        using (FileStream pdfOutputFile = new FileStream
                                          (outputFilePath, FileMode.Create))
        {
            PdfStamper formFiller = null;
            try
            {
                formFiller = new PdfStamper(reader, pdfOutputFile);
                AcroFields quote_template = formFiller.AcroFields;
                //Fill the form
                quote_template.SetField("OldAddress", address);
                //Flatten - make the text go directly onto the pdf 
                //          and close the form.
                //formFiller.FormFlattening = true;
            }
            finally
            {
                if (formFiller != null)
                {
                     formFiller.Close();
                }
            }
        }
    }
    finally
    {
        reader.Close();
    }
    //Process.Start(outputFilePath); // does not work
}

因为这是关于ASP.NET的标签，所以你不应该使用Process.Start（），而是使用像这样的代码：

private void respondWithFile(string filePath, string remoteFileName) 
{
    if (!File.Exists(filePath))
        throw new FileNotFoundException(
              string.Format("Final PDF file '{0}' was not found on disk.", 
                             filePath));
    var fi = new FileInfo(filePath);
    Response.Clear();
    Response.AddHeader("Content-Disposition", 
                  String.Format("attachment; filename=\"{0}\"", 
                                 remoteFileName));
    Response.AddHeader("Content-Length", fi.Length.ToString());
    Response.ContentType = "application/octet-stream";
    Response.WriteFile(fi.FullName);
    Response.End();
}

这将使浏览器提供保存/打开对话框。

尝试使用iTextSharp创建PDF后打开PDF，但无法使其工作？
