使用SocketException连接到SFTP服务器时，"SocketException:无法解析主机“

Question

试图将文件上传到本地的SFTP服务器。连接SFTP时命中错误。

Ftp://localhost‘：无法解析主机的System.Net.Sockets.SocketException

我试过使用命令行和FileZilla连接。它可以连接。

string host = "sftp://localhost";
int port = 22;
string username = "gth";
string password = "1234";
using (SftpClient client = new SftpClient(host, port, username, password))
{
    client.Connect();
}

它显示了下面的错误：

Answer 1

host构造函数的SftpClient参数采用主机名称，而不是URL。

所以只要放下sftp://

host = "localhost";

Answer 2

或者使用127.0.0.1代替本地主机
