我正在尝试连接到客户端服务器上的mysql数据库。我遇到的问题是，当本地机器上的mysql正在运行时。我的windows服务试图连接到我的sql客户端时出错ç An attempt was made to access a socket in a way forbidden by its access permissions 似乎我们的本地mysql正在使用3306端口并阻塞它。如果我在服务器上停止mysql并运行windows服务，就可以了。我怎么才能避开这个？

PasswordConnectionInfo connectionInfo = new PasswordConnectionInfo("########",####, "######", "#######");
connectionInfo.Timeout = TimeSpan.FromSeconds(500);
SshClient client = new SshClient(connectionInfo);
client.Connect();
ForwardedPortLocal portFwld = new ForwardedPortLocal("127.0.0.1",3306,"127.0.0.1", 3306); client.AddForwardedPort(portFwld);portFwld.Start();
// using Renci.sshNet 
DBConnect connection = new DBConnect(portFwld);
