Connector/net - Access Denied problem

[Kevin]

I just downloaded the Connector/Net so I could use it in my C# application and am having a connection problem. Whenever I try to actually open the connection it always returns "Acess Denied For User <user> (Using Password: ...)" I've tried several different users that I know work but I get the same result.

This is how I'm opening the connection.

string ConnectStr="Database=" + Database + "; Data Source=" + ServerName +
"; User Id=" + Username + "; PASSWORD=" + Password + "; ";

dbSrv=new MySqlConnection(ConnectStr);

dbSrv.Open();

Any ideas on what the problem could be?
