        [DllImport("User32.dll")]

        private void BtnSend_Click(object sender, EventArgs e)

            foreach (Process proc in processes)
            {
                if (proc.MainWindowTitle != string.Empty)
                {
                    IntPtr handle = proc.MainWindowHandle;
                    SetForegroundWindow(handle);
                    ShowWindow(handle, 3);
                    //SendKeys.Send("123456");
                    //SendKeys.Send("{ENTER}");
                    //SendKeys.Send("567890");
                    //SendKeys.Send("{ENTER}");

                    Send(null, null);
                }
            }

        }

        private void Send(Dictionary<string, string> dict, Dictionary<int, string> configs)
        {

             dict = new Dictionary<string, string>()
            {
                {"carton","carton12345679" },
                {"sn","sn12345679" },
                {"pallet","pallet12345679" },
                {"boxno","boxno12345679" }
            };

            configs = new Dictionary<int, string>()
            {
                { 4,"pallet"},
                { 1,"carton"},
                { 2,"sn"},
                { 3,"boxno"},
            };

            var sort = configs.OrderBy(r => r.Key);
            foreach (var config in sort)
            {
                SendKeys.Send(dict[config.Value]);
                SendKeys.Send("\r\n");
            }
        }
    }
}

 可以使用json传入数据和发送顺序的配置，例如：

cofigs:

{
  "4": "pallet",
  "1": "carton",
  "2": "sn",
  "3": "boxno"
}

data:

{
    "carton": "carton12345679",
    "sn": "sn12345679",
    "pallet": "pallet12345679",
    "boxno": "boxno12345679"
}

然后通过反序列化的方式把它们赋值给字典dictionary，然后执行发送。
