Question

我正在从表单上的文本框中获取信息，然后通过一种方法将其传递给类（仍在学习中）。我发送的信息可以很好地传递。在我的代码下面，我按它们的工作顺序列出了它们。

第一步是获取传递的数字（第一组代码。），然后使用方法将其传递给类，该方法被设置为用户控件（第二组代码）。它经历了步骤，然后将其带到另一个类（第三组代码）以返回框内所需的值。然后它返回并应该将其张贴在框中，但是事实并非如此。

我在这方面还很陌生，需要一些帮助。

谢谢

Answer 1

最终的结果是我刚制造的“用户控制”，我已制成，所以我可以隐藏起来，当我点击按钮的参考。

因此，当我单击按钮时，它将引用我在AccountStatus用户控件中设置的功能。

accountStatus.grabStatus(accountInformation.accountNumber.Text);

引用了

  grabStatus(string accountNum)
  {
    dataAccess da = new dataAccess(); 
    List<Information> status = new List<Information>(); 
    status = da.GetStatus(accountNum); 
    ListBoxPeople.DataSource = status; 
    ListBoxPeople.DisplayMember = "FullInfo";
  }

为什么我的数据没有发布到列表框中？
