[待解决问题]
本人开发一个短信猫池程序，16口的猫池，程序采用16个串口类 分别发送AT指令读取16个COM口的配置信息，有时候程序会闪退，我的提取串口信息写在串口接收事件里了 用的是SerialPort类 下面是错误提示
接收返回消息异常CurrentDomain_UnhandledException！具体原因：System.ObjectDisposedException: 已关闭 Safe handle
在 System.Runtime.InteropServices.SafeHandle.DangerousAddRef(Boolean& success)
在 System.StubHelpers.StubHelpers.SafeHandleAddRef(SafeHandle pHandle, Boolean& success)
在 Microsoft.Win32.UnsafeNativeMethods.GetOverlappedResult(SafeFileHandle hFile, NativeOverlapped* lpOverlapped, Int32& lpNumberOfBytesTransferred, Boolean bWait)
在 System.IO.Ports.SerialStream.EventLoopRunner.WaitForCommEvent()
在 System.Threading.ThreadHelper.ThreadStart_Context(Object state)
在 System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean ignoreSyncCtx)
