未处理的“System.Runtime.InteropServices.SEHException”类型的异常出现

采用tcp/IP网络传输机制，有2个线程，其中线程A中有文件读取动作，有数据库插入，有向服务器端传输数据的动作；另外一个线程B中有文件读取动作，有向服务器传输数据工作，没有数据库操作。rnrn当我断掉网络的时候，会有机制另程序重新连接服务器，可是程序会死在插入数据库的函数中，而且每一次都死在数据库插入函数中，如果是win32 平台情况下，则提示的是：rn未处理的“System.Runtime.InteropServices.SEHException”类型的异常出现，rn如果是vc/mfc的平台下，则提示异常。rnrn但都是死在数据库插入函数中。rn有人遇到过这种情况吗？？实在是不明白！rn

未处理的异常

在某一个项目中，一开始没出现这个错误，后来过了一年后，再运行这个程序的时候，总是报堆栈溢出的错误。经过好几天的折腾，配置环境，调整视频格式，终于发现，其实是有一行代码的内存过大，所以才会溢出，遇到此类问题的时候，一定要仔细排查整个项目中所有的和内存相关的代码。因为在这个项目中，在函数的第一句就报错了，误导了我们，让我们以为是opencv封装的函数的问题，其实是这个函数中的某一句话出现了问题。。。为...
