获取数据方法：

public static DataTable GetData(string query, string database,
             string host, string port, string login, string password)
    {
        OleDbConnection connection = null;
        try
        {
            connection = Connection.GetConnection(database, host, port, login, password);
            OleDbDataAdapter dataAdapter = new OleDbDataAdapter(query, connection);
            DataSet dataSet = new DataSet();
            dataAdapter.FillSchema(dataSet, SchemaType.Mapped);
            dataAdapter.Fill(dataSet);
            return dataSet.Tables[0];
        }
        finally 
        {
            Connection.CloseConnection(connection);
        }
    }

连接字符串：

connectionString = string.Format("Provider=IBMDADB2;
                    Database={0};Hostname={1};
                    Protocol=TCPIP;Port={2};
                    Uid ={3};Pwd={4};", 
                    database, host, port, login, password);
