非常接近，要访问变量的Value，您需要点击该属性

So very close, to access the Value of a variable, you need to hit that property

public void Main()
{
    Variable resultSet = Dts.Variables["User::ZBatch_Order_Export_ResultSet"].Value;

    // do stuff here with resultSet and the webservice

    Dts.TaskResult = (int)ScriptResults.Success;


}
