以上是在不引⽤WEB服务的条件下动态调⽤WEB服务⽅法，如果该服务地址不确定或后期有可能会变动，则采⽤上述这些⽅法会⽐较好，当然如果服务地址不会出现变更的情况下，可以在VS中直接引⽤WEB服务，然后就可调⽤⾃动⽣成的SOAPClient类来调⽤相应的WEB服务⽅法，这样就简单很多，
如下：
avar client = new SmsService.wmgwSoapClient(); //wmgwSoapClient就是引⽤WEB服务后⾃动⽣成的类
string result = client.MongateSendSubmit(tuserId.Text, tpassword.Text, tpszMobis.Text, tpszMsg.Text, int.Parse(tiMobiCount.Text),
tpszSubPort.Text, tMsgId.Text);
