我为 PLC 创建诊断应用程序。我有一个表单和几个控件，它们是从 UserControl 继承的。这个控制我切换。一种视图是仪表板、图表等。当图形运行时，会发生异常。Form1.Designer.cs 中的“base.Dispose(disposing)”行显示异常。你有什么想法，我该如何解决？感谢您的任何想法。
这是 Form1.Designer.cs 的代码。错误显示在线 base.Dispose(disposing)。基本上我不知道这部分代码是做什么的。我无法修复它。有人可以告诉我，它是如何工作的吗？这部分什么时候调用？我在我的程序中没有发现 Dispose() 方法的任何用途，仅覆盖每个 Control 中的方法（从 UserControl 继承）。谢谢
