How to include sid and port into an oracle connection string?

Question

I would like to specify the port and sid in the connection string. After the following code runs

public static string ConnectionString
{
    get
    {
        string host = Config.CsHost;
        string sid = Config.CsSID;
        string port = Config.CsPort;
        string user = Config.CsUser;
        string pass = Config.CsPassword;
        return String.Format(@"Data Source = {0}:{1}\{2}; Persist Security Info = True; User Id = {3}; Password = {4}; Unicode = True", host, port, sid, user, pass);
    }
}

...

using (OracleConnection connection = new OracleConnection(ConnectionString))
{
    try
    {
        connection.Open();

the Open() doesn't respond... The problem is with the sid I think. What might be the problem?

UPDATE: I should use this kind of connection string. But I can't interpret it well.

Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=MyOracleSID))); User Id=myUsername;Password=myPassword;

Can someone help me interpret this?

Answer 1

I had to replace SERVICE_NAME to SID, so this:

return String.Format("SERVER=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST={0})(PORT={1}))(CONNECT_DATA=(SID={2})));uid={3};pwd={4};", host, port, sid, user, pass);

did the trick.
