我有一个树视图，其中有一组文档列表和另一个包含患者详细信息的网格。我需要做的是，当我们从树视图中选择文档（选择多个..复选框已启用）并且从网格中选择患者并单击按钮时，应该使用 ITEXTSHARP 创建所有文档。即创建了多个文档。我是这样试的

点击按钮

 foreach( TreeNode node in TreeView1.Nodes)
    {
        if (node.ChildNodes.Count>0)
        {
            for(int i=0 ;i<(node.ChildNodes.Count);i++)
            {
                if (node.ChildNodes[i].Checked==true)
                {
                    string nodevalue = node.ChildNodes[i].Value.ToString();

                    if (nodevalue=="3")
                    {
                        foreach (GridViewRow row in GridView1.Rows)
                            {
                                if (row.RowType == DataControlRowType.DataRow)
                                {
                                    CheckBox chk = row.FindControl("CheckBox1") as CheckBox;
                                    if (chk.Checked)
                                    {
                                        Label lbl_name = row.FindControl("Label1") as Label;
                                        Label lbl_dob = row.FindControl("Label3") as Label;
                                        pdf_abcd(lbl_name.Text.Trim(), lbl_dob.Text.Trim());
                                    }
                                }
                            }
                    }


                    }
                }
            }
        }
    }


}

并且 pdf_abcd 函数是

和

private void ShowPdf(string strS)
{
    Response.ClearContent();
    Response.ClearHeaders();
    Response.ContentType = "application/pdf";
    Response.AddHeader("Content-Disposition", "attachment; filename=" + strS);
    Response.TransmitFile(strS);
    Response.End();
    Response.Flush();
    Response.Clear();

}

但是系统只下载一个文档..任何人都可以帮助我

如果您退后一步，暂时忽略 PDF，只专注于 HTTP 请求和响应，您应该会得到答案。当浏览器发出 HTTP 请求（您的按钮单击）时，服务器被允许发送一个且仅一个响应。您的代码正在尝试（未成功）向浏览器发送多个响应。第一次Response.End被称为管道实际上会终止，并且您的其余代码不会运行。

解决方案是一次性制作一个巨大的 PDF，制作单个 PDF 并合并 它们，或者创建一个包含所有 PDF 的 zip 文件。

如果你想你有不同Open的file in new tab方法：

方法一：

Response.Clear();
Response.ContentType = "application/pdf";
Response.AppendHeader("Content-Disposition", "attachment; filename=foo.pdf");
Response.TransmitFile(filePath);
Response.End();

方法二：

Process process = new Process();
process.StartInfo.UseShellExecute = true;
process.StartInfo.FileName = outputPdfFile;
process.Start();

希望这对你有帮助！
