使用短信网关，有第三方的，也有和移动电信等签约的。后者一般是大客户才开放。前者你百度搜“短信通”就可以找到很多家提供这种服务的公司。提供的接口一般是http协议的调用。在C# WINFORM里就可以使用WebClient类来调用了。具体的接口你还是得看不同公司提供的文档。
使用短信猫。是一个硬件设备，可以插SIM卡，然后通过短信猫提供的API去调用…具体还是得看那个API…我用过一个是提供一个dll给你import的。其他应该也一样
Visual C#实现短信息发送的具体实现步骤：
Visual C#发送短信息的关键就是通过Web引用新浪网提供的发送短信息的Web Service，并在引用完成后。调用此Service的sendXml方法即可。以下就是Visual C#引用Web Service发送短信息的具体实现步骤：
1. 启动Visual Studio .Net。
2. 选择菜单【文件】|【新建】|【项目】后，弹出【新建项目】对话框。
3. 将【项目类型】设置为【Visual Basic项目】。
4. 将【模板】设置为【Windows应用程序】。
5. 在【名称】文本框中输入【短信】。
6. 在【位置】的文本框中输入【E:/VS.NET项目】，然后单击【确定】按钮，这样在"E:/VS.NET项目"目录中就产生了名称为"短信"的文件夹，并在里面创建了名称为"短信"的项目文件。
7. 把Visual Studio .Net的当前窗口切换到【Form1.cs（设计）】窗口，并从【工具箱】中的【Windows窗体组件】选项卡中往Form1窗体中拖入下列组件，并执行相应的操作：
四个Label组件。
四个TextBox组件。
一个Button组件，其作用是发送短信息。并在这个Button组件拖入Form1的设计窗体后，双击它，则系统会在Form1.cs文件分别产生这个组件的Click事件对应的处理代码。
8. 把Visual Studio .Net的当前窗口切换到Form1.vb的代码编辑窗口，并用下列代码替换Form1.cs中的InitializeComponent过程对应的代码，下列代码作用是初始化窗体中加入的组件：
private void InitializeComponent ( )

你不用程序的情况能不能用TAB切换焦点。如果这样不行的话你用程序控件是没用的。
或都直接对第二个编辑框发送消息。
服务器先进行
Bind ()绑定服务器的端口
然后BeginReceive接受客户端发送的数据
客户端Bind ()绑定客户端接受和发送数据的端口
SendTo()来发送数据就可以
不需要进行BeginConnect，因为UDP不需要连接
用 vb.net socket通信
