使用了与请求协议不兼容的地址

Question

代码如下

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"与请求的协议不兼容的地址被使用"异常。

Answer 1

IPv6链路地址在每个链路上都是有效的，所以您需要告诉系统使用哪个链路。这通常是通过在地址后面附加%和接口id来完成的。使用全局地址通常更容易。

Answer 2

我在FTP服务器上上传文件夹时得到这个错误:

使用了与请求协议不兼容的地址

有时上传成功，有时上传失败。
