mm1接口也就是手机终端和mmsc(中国移动就是http://mmsc.monternet.com)用来发送mms message的接口, GPRS modem当然也是可以使用这一接口发送的.

/* 发送MMS的过程
1> 创建消息发送接口
MMSender ms = new MMSender();
2> 设置参数属性
默认属性已经是中国移动参数,因此如果是中国移动用户,以下两个操作可以不需要
ms.SetMMSC("http://mmsc.monternet.com");
ms.SetProxy("10.0.0.172:80");
3> 创建消息
MMessage mm= new MMessage();
4> 设置消息内容
mm.SetSubject("标题"); // 设置标题
mm.AddTo("13825271511"); // 添加接收号码,调用一次添加一个接收号码
mm.AddFile("FileName"); // 添加发送文件,包含文件路径,调用一次添加一个发送文件
5> 发送消息
string szReult =ms.Send(mm);
6> 继续发送其他号码
mm.ClearTo();
mm.AddTo("13812345678");
ms.Send(mm);
