您需要托管asp.net网应用程序/网站的服务器上您的浏览器客户端计算机。你的客户会从服务器和网站无法客户机上托管请求的页面。所以，你可以将设备连接到服务器计算机和客户端发送您请求后，通过设备例如GSM调制解调器的数据。现在，您需要将设备连接到服务器，并可以使一个窗口服务，从数据库中提取的信息发布设备，通过张贴他们。
You need to host asp.net net application/website on a server your browser is a client machine. Your client will request a page from server and website could not be hosted on client machine. So you can connect your device to server machine and client sent you request to post data through device e.g gsm modem. Now you need to connect your device to server and you can make a windows service to pull the posted message from database to post them through device.
您需要跟COM端口，甚至你的USB设备监听COM端口。可以使用串行端口类设备进行通信。您可以使用桌面应用程序和为此，我看不到任何理由使用网站。下面的链接将帮助你。
