.net用sock通讯
请问下哪位大哥有.net做的sock通讯 只要能实现两台电脑互相通信就可以了。我想在源码作参考谢谢..如果有愿帮助小弟的大哥。大姐。请加我QQ。。在线等394858307谢谢.有要求也可以提的。 --------------------编程问答-------------------- 网上多的是。随便搜。 --------------------编程问答-------------------- 你有打这些字的时间，都能搜到并运行了 --------------------编程问答-------------------- UP/// --------------------编程问答-------------------- MSDN --------------------编程问答--------------------Up --------------------编程问答-------------------- 不知道 --------------------编程问答-------------------- MSDN就有了 --------------------编程问答-------------------- UP. --------------------编程问答-------------------- 客户机
