用C#实现Windows Mobile 发送短信
窗口短信：
窗口短信实现比较简单，可以直接使用下面的启动参数启动系统的EXE文件即可， System.Diagnostics.Process.Start("tmail.exe", "-transport \"SMS\" -to \"" + 手机号码 + "\" -body \"短信内容\"");但要注意的是，在发送完毕后，短信列表页面会在你关闭发送信息窗口后呈现出来，可以在页面的关闭事件中，使用FindWind方法，找到系统的【短信】窗口，将其关闭即可。
无感知短信
1.Windows Mobile 5.0及以上版本
无感知短信接口与Mobile操作系统的版本有关，如果是基于Windows Mobile5.0 的设备 ，完成短信发送比较容易，因为微软已经给你封装好了底层的API，可以直接进行调用，引用Microsoft.WindowsMobile.PocketOutlook.dll后，使用SmsMessage smsSend = new SmsMessage(phone, sms);smsSend.Send();方法便可以完成对一条短息的发送。
2.Windows Mobile 2003或Windows Mobile2003SE设备. V*L:W"O5e
在5.0以前的版本，虽然现在使用量比较小了，但是在2年前，在其上面发送短息可以说很是费劲，当时确实还让我头疼了一段时间，需要用户自己封装底层的API，然后进行调用，我这里有一个，贴出来，以供大家参考
