错误码为0xc0000005.此错误可能是cl"中的错误

让我先解释一下我的程序和正在发生的事情。我的程序使用GSM调制解调器从移动卡中读取消息，然后在Marquee中显示消息…这个错误真的是随机的，我在一个朋友的迪斯科舞厅测试了这个程序，有时它可以整夜工作而不会崩溃，有时它会一次又一次地崩溃……所以，有一个类的代码做Marquee(这是它崩溃的地方):

好了，就这些……

我一遍又一遍地搜索，但我无法修复它或找到任何解决方案…编辑:到目前为止，我所做的更改已在我的代码中更新，我注释了线程内的行，并添加了您告诉我要做的foreach循环

完整错误:

运行时遇到致命错误。错误的地址在0x5f44a62c，线程0x2040。错误码为0xc0000005。此错误可能是CLR中的错误，也可能是不安全或不可验证的错误部分用户代码。此错误的常见来源包括userCOM-interop或PInvoke的封送错误，这可能会损坏堆栈。
