General select statement to stored procedures

I'm trying to write a general function to several specific stored procedures, but I'm afraid that it will cause errors that I don't see now. The function is to get the name of the stored procedure as a string, and get a list of objects that contain the parameters of the stored procedure. Does it look good to you?

public static DataTable SelectQuery(string storedProcedureName, List parameters)
    {
        DataTable dt = new DataTable();
        OleDbConnection con = WorkerDB.GetConnection();
        OleDbCommand cmd = new OleDbCommand();
        cmd.CommandText = storedProcedureName;  
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Connection = con;
        for (int i = 0; i < parameters.Count; i++)
        {
            cmd.Parameters.AddWithValue("?", parameters[i]);
        }
        try
        {
            con.Open();
            OleDbDataAdapter da = new OleDbDataAdapter(cmd);
            da.Fill(dt);
            da.Dispose();                
        }
        catch (Exception ex)
        {

            throw ex;
        }
        finally
        {
            con.Close();
        }

        return dt;
    }

This is first refactored version of your code. I have changed following thing

• If any object provide dispose method , prefer using statement.

• Use dictionary rather than list of parameter as you have a possibility of specifying param names also

• Current implementation sticks only to datatable , you might need to think about the datareader.

• naming of variable should be explicit.

Few more things needs to be thought like out param if you need.

public static DataTable ExecuteDataTable(string queryName, CommandType commandType, Dictionary parameters=null)
{
    using (OleDbConnection connection =  WorkerDB.GetConnection())
    {
        using (var command=new OleDbCommand())
        {
            connection.Open();
            command.CommandText = queryName;
            command.CommandType = commandType;
            command.Connection = connection;

            if (parameters != null)
            {
                foreach (var parameter in parameters)
                {
                    command.Parameters.AddWithValue(parameter.Key, parameter.Value);
                } 
            }

            var dataAdapter = new OleDbDataAdapter(command);
            var dataTable = new DataTable();
            dataAdapter.Fill(dataTable);
            dataAdapter.Dispose();

            return dataTable;
        }
    }
}
