如何合并多个pdf文件(在运行时生成)ItextSharp然后打印它们.

我找到了以下链接,但该方法需要pdf名称考虑到存储的pdf文件,这不是我的情况.

我有多个报告我会pdf files通过这种方法将它们转换为:

private void AddReportToResponse(LocalReport followsReport)
{
    string mimeType;
    string encoding;
    string extension;
    string[] streams = new string[100];
    Warning[] warnings = new Warning[100];
    byte[] pdfStream = followsReport.Render("PDF", "", out mimeType, out encoding, out extension, out streams, out warnings);
  //Response.Clear();
  //Response.ContentType = mimeType;
  //Response.AddHeader("content-disposition", "attachment; filename=Application." + extension);
  //Response.BinaryWrite(pdfStream);
  //Response.End();
}

现在我想将所有生成的文件(Bytes)合并到一个pdf文件中进行打印
