使用了与请求的协议不兼容的地址？答案

【问题标题】：An address incompatible with the requested protocol was used?使用了与请求的协议不兼容的地址？
【发布时间】：2014-06-17 18:38:50
【问题描述】：

这是代码

Socket socket = new Socket(AddressFamily.InterNetworkV6, SocketType.Stream, ProtocolType.Tcp);
socket.Connect("fe80::fc33:41d6:77f4:c8c7", 1000);

当我尝试连接此地址时，我得到“使用了与请求的协议不兼容的地址”异常。

标签： c# ipv6

【解决方案1】：

IPv6 链路专用地址在每个链路上都有效，因此您需要告诉系统要使用哪个链路。这通常通过将 % 和接口 ID 附加到地址来完成。使用全局地址通常更容易。

在我的 FTP 服务器上上传文件夹时出现此错误：

使用了与请求的协议不兼容的地址

有时会成功上传，但有时会失败。
