c# - Windows 窗体 - 打开新线程时如何防止 System.AccessViolationException

Question

我希望这个问题对某些人来说是显而易见的 😊 我有一个 Windows 窗体应用程序，它在单独的子窗体上执行一些独立的进程。它有一个首先打开的主窗体，然后它根据每个子窗体的“事件”数据库值打开子窗体。此过程经常按预期运行数小时而没有任何问题……必要时打开和关闭。我无法弄清楚的问题是应用程序只是卡住，必须手动关闭并重新启动，当然，当它不运行时，它会完全停止处理。

Windows 应用程序错误日志中始终有 2 个错误。第一个是“.Net 运行时”，第二个是“应用程序错误”。第三个信息条目似乎在应用程序重新启动时被记录，但不能 100% 确定它是否在重新启动之前存在。

MainForm 使用不同版本在新线程中打开不同的子表单:

try
{
Thread CS = new Thread(new ThreadStart(CS_Start));
CS.SetApartmentState(ApartmentState.STA);
CS.Start();
}
catch { }

这是在打开子表单之一的新线程中调用的代码......

private void CS_Start ()
        {
            try
            {
                using (CS_Searches CS_SearchForm = new CS_Searches())
                {
                    if (!CS_SearchForm.Visible)
                        CS_SearchForm.ShowDialog();
                }
            }
            catch { }
        }

MainForm 打开了 5 个单独的窗体。每个表单都执行完全独立的任务，并且还会根据“处于事件状态”值使用以下方法关闭自身:this.Dispose();

问题似乎总是发生在不同的 CS.Start();线。我曾 try catch 错误，但不幸的是它从未遇到此代码。我还通过添加 using 语句修改了 CS_Start。不幸的是，我一直无法复制这个问题，因为它运行得很好，直到它没有运行，而且频率可能遍布整个 map 。根据我所有的谷歌搜索，它似乎是内存访问冲突，但我没有运气确认这一点或找到修复方法。如有任何帮助，我们将不胜感激。

谢谢，格雷格

这真的很有趣 - 您可以制作转储并使用 WInDbg 探索它们。但我会考虑创建与 Console Application 相同的应用程序并探索其行为。结果可能是某种 GUI 相关的错误/功能，您达到了处理程序/GDI 限制或类似的东西。
