好的，这应该是基本的，但我找不到好的答案。我只想在 BackgroundWorker 内抛出的异常中进行 VS 中断。代码示例：

    private void btnBGWorker_Click(object sender, EventArgs e)
    {
        BackgroundWorker bgWorker = new BackgroundWorker();
        bgWorker.DoWork += bgWorker_DoWork;
        bgWorker.RunWorkerCompleted += bgWorker_RunWorkerCompleted;
        bgWorker.RunWorkerAsync();
    }

    void bgWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
    {
        //I know e.Error have the Exception but
        if (e.Error != null)
            throw e.Error; //Well this does not work, VS will throw TargetInvocationException
    }

    void bgWorker_DoWork(object sender, DoWorkEventArgs e)
    {
        //** How can I make VS break here !!!??? **
        throw new NotImplementedException();
    }

【解决方案1】：

您可以转到“调试”>“异常”菜单，然后确保在“公共语言运行时异常”旁边的“抛出”列中有一个复选标记。这将使 Visual Studio 中断所有异常从您的 CLR 代码中抛出。
