像try{…}catch(Exception){…}这样的代码，我们知道是抓不住Non CLS Compliant的Exception的。但是就一定能抓住CLS Compliant的Exception吗?事实发现从.net 4.0开始未必。
QA报告了一个问题，说点了一个按钮之后系统弹了一个框说Fatal Application
Error，提示重启。QA抓了一下log和dump就重启继续测了。这个问题之前从来没发生过，之后也重现不出来，但就发生了那么一次,而且是很normal的workflow。这种对话框是我们系统处理AppDomain.CurrentDomain.UnhandledException的标准错误框，这种问题我们的日志里面会有详细的Exception的call
stack,一般来说应该在某个地方加条件判断或者try/catch一下，轻松搞定
看了一下日志，全是底层的函数，没见我们的代码。

然后又看了一下Button Click代码，类似是这样的
|
try { Clipboard.GetDataObject(); … Clipboard.SetDataObject() … } catch (Exception ex) { //log and ignore } |
这个… Exception没抓住! 为什么?为什么?!
只能看dump了
#看看主线程在干嘛

嗯，QA确实是点了一个按钮，然后当前call stack也看不出更多信息。(~* e!clrstack也没啥有用信息)

接下来只能去拷问google了…
功夫不负有心了，终于找到相关的文章,原来.net4.0里面加了Corrupted State Exceptions这个东东，具体描述及解决方案可以参考下面的链接。

“In .NET 4.0, the runtime handles certain exceptions raised as Windows Structured Error Handling (SEH) errors as indicators of Corrupted State. These Corrupted State Exceptions (CSE) are not allowed to be caught by your standard managed code. I won‘t get into the why‘s or how‘s here. Read this article about CSE‘s in the .NET 4.0 Framework:” Handling Corrupted State Exceptions http://msdn.microsoft.com/en-us/magazine/dd419661.aspx#id0070035 |
另外，强烈推荐Windows Structured Error Handling必读的经典作(A Crash Course on the Depths of Win32? Structured Exception Handling http://www.microsoft.com/msj/0197/exception/exception.aspx)
