There are nested exceptions on this thread. Run with -nested for details那现在问题来了我想看所有异常的详细信息怎么办呢人肉一个一个的用 !pe 命令去执行那将会多恶心。。。所以友好的方式就是写脚本去提速这里我使用 .foreach 命令。.foreach (ex {!dumpheap -type Exception -short}){.echo ********************************;!pe ${ex} }上面我用了一个 -short 参数目的就是只输出 address 地址方便脚本遍历然后将迭代项送入 !pe 输出结果如下0:015 .foreach (ex {!dumpheap -type Exception -short}){.echo ********************************;!pe ${ex} }

There are nested exceptions on this thread. Run with -nested for details当然你也可以打印出当前异常的内部异常配上一个 -nest 参数即可。.foreach (ex {!dumpheap -type Exception -short}){.echo ********************************;!pe –nested ${ex} }
