除了使用自定义类外，还可以使用OpenNetCF这个工具包 可以到这里下载 http://www.opennetcf.org ，目前版本1.4 安装后，引用OpenNETCF.Phone 然后代码如下： .... using OpenNETCF.Phone; using OpenNETCF.Phone.Sms; private void menuItem2_Click(object sender, System.EventArgs e) { if((textBox1.Text.Trim().Length>0) &&(textBox1.Text.Trim().Length>0)) { Sms mySMS=new Sms(SmsMode.Send); SmsAddress myAddr=new SmsAddress(); myAddr.Address="+86"+textBox1.Text; myAddr.Type=AddressType.International; int smsHandle=mySMS.SendMessage(myAddr,textBox2.Text); } } 要特别注意的是，当你的系统中有Framework 1.1以及FrameWork 2.0时,加载dll会有问题，解决方法如下 将/Program Files/Microsoft Visual Studio .NET 2003/CompactFrameworkSDK/v1.0.5000/Windows CE/中的OpenNETCF.Phone.dll拷贝到项目目录中，并在项目中包含此dll文件即可。
