c# - 我该如何调试这个与线程相关的错误

Question

我有一个大项目，当我按下一个按钮时，我开始了一个任务:

Task.Factory.StartNew(() =>
{
    CreatePortfolio();
});

表单有一个 MSChart，我为每个访问图表的方法都有一个委托(delegate)。

当我单步执行代码时，不会抛出任何错误。但是当我运行它时，我得到了这个错误 - 但不知道它来自哪里，因为它显示在下面的 Application.Run 行上:

public static string[] MainArgs;
[STAThread]
static void Main(string[] args) 
{
    CheckForIllegalCrossThreadCalls = false;
    MainArgs = args;

    Application.Run( new MainForm( ) ); //ERROR shown here
}

异常(exception)情况:

System.ArgumentOutOfRangeException was unhandled
  HResult=-2146233086
  Message=Years value must be between +/-10000.
Parameter name: years
  Source=mscorlib
  ParamName=years

我认为您在某些时候正在使用 DateTime.AddYears 并且传递给 add years 的值无效。

请检查我认为您正在使用某个数组并从该数组的某个索引传递值，并且在某一时刻传递了数组中不可用的值。这是你的问题
