我为PLC创建诊断应用程序。我有一个表单和几个控件，它们继承了UserControl。这控制我切换。一种视图是仪表板，图形等。图表运行时，会发生异常。 Form1.Designer.cs中的“base.Dispose（disposing）”行显示异常。你有什么想法，我怎么解决它？谢谢你的任何想法。
这是Form1.Designer.cs的代码。错误显示在行base.Dispose（disposing）上。 Basicaly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？这个部分何时被称为？我没有在我的程序中找到任何方法Dispose（），只重写每个Control中的方法（继承自UserControl）。感谢

答案 0 :(得分：1)
您似乎是从GUI线程以外的线程调用Dispose。你不能这样做。
答案 1 :(得分：0)
您需要更加具体 - 可能会在您尝试做的事情中添加一些代码，在哪里？
[编辑]
正如吉姆所说，你是从一个单独的线程引用一个表单;
以下是例外情况：
System.InvalidOperationException未被用户代码处理 消息=跨线程操作无效：访问控制'Form1' 来自其在
上创建的线程以外的线程
这意味着您正在尝试从未创建的线程中处置Form1。
你是否在应用程序中运行了sperate线程，如果有，这是第一个看的地方。
您是否在代码中的任何位置关闭Form1？
