如何在.net中编写pdf文件时隐藏打开的对话框

Question

我正在使用以下命令在c＃.net

中创建pdf文档

    Response.Clear();
    Response.ClearHeaders();
    Response.ClearContent();
    Response.ContentType = "application/pdf"; //"application/pdf";
    Response.AddHeader("content-length", stream.Length.ToString());
    Response.AddHeader("content-disposition", "attachment;filename=" + string.Format("d:\\members-{0}.pdf", string.Format("{0:ddMMyyyy}", DateTime.Today)));
    Response.ContentEncoding = new System.Text.UTF8Encoding(); 
    Response.BinaryWrite(stream.ToArray());
    Response.Flush();
    stream.Close();
    Response.End();

注意：stream是我想写的内容

问题：始终打开对话框，它要求我保存所有时间。我想隐藏此对话框并将文件保存在任何需要的位置。请帮帮我
