Question

我有一个vs2010 c＃解决方案昨天工作正常。

当我今天尝试运行一个调试实例时，我不断处理SEHException。

启动表单的InitializeComponent方法中抛出此错误。

任何想法？

这是堆栈跟踪：

随机记录我的gf昨晚打破了我的笔记本电脑屏幕，所以我在外接显示器上运行......这可能与它有什么关系吗？

这是代码和错误的行..

private void InitializeComponent()
{
    this.components = new System.ComponentModel.Container();
    ///////////////////The line below throws the exception
    this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
    /////////////////////////////// 
    this.Text = "Form1";
}

这可能与昨天开始发生的广泛报道的问题相同。参见

如果你的机器上有“Trusteer Rapport”，请尝试卸载

老实说，zeroid的答案并没有解决我的问题。所以为了完整起见，我想补充说avira也造成了这样的问题

Answer 3

在主线程中加载非托管函数（来自DLL）时，可能会发生此问题。我通过在与主线程不同的线程中加载这些非托管函数来解决此问题，例如，您可以使用BackgroundWorker。

Answer 4

我偶然发现了这一点，因为我突然遇到了同样的问题。在OP之后的几年，我正在使用VS2015。昨天我的解决方案工作正常，我的笔记本电脑连接到外接显示器。今天我在家工作，没有额外的显示器。除了OP关于切换屏幕设置的评论之外，我不会认为它是相关的。

SEHException未得到处理
