C# 远程桌面、电子白板、视讯、摄像头、话筒通信源码下载

【实例简介】

试用说明：

（1）将服务端部署到一台服务器上，然后启动OMCS.Server.exe。

（2）修改客户端配置文件中的服务器的IP，在一台机器上启动客户端，登录一个帐号，比如aa01.

（3）在另一台机器上启动客户端，登录另一个帐号，比如aa02.

（4）aa01可以在主界面的TextBox中中输入aa02，并点击后面的按钮，来连接aa02的视频。

（5）aa02也可以在其UI中输入aa01，并点击后面的按钮，来连接aa01的视频。

（6）测试视讯时，两个客户端最好在不同的房间。

（7）测试白板时，需要连接到同一个用户的白板，才能协同。
