Question

我试图对托管内存泄漏进行故障排除，下面的信息对我来说没有意义，因为我希望看到一些静态方法或类似的东西，对于！gcroot命令，但找到下面的内容。

Answer 1

正如我在评论中所说，您应该更新版本以便CLR和SOS匹配，否则您可能会看到不正确的输出。

堆栈只显示该对象由r12中的代码使用的寄存器（在本例中为ThreadProc()）生根。回想一下，对象可以通过以下方式生根：

堆叠/寄存器
GC Handle
终结者队列
上述任何一项中发现的物体的成员

Answer 2

您可以使用'.chain'命令来显示已加载的DLL。然后你可以使用'.unload path'来卸载除非DLL，然后重新加载匹配DLL你将解决这个问题。关于如何获取匹配DLL，您可以检查目标机器路径'％windir％\ microsoft.net \ framework \＆lt; .NET version＆gt;'那么你可以得到匹配的DLL

ThreadProc在GCroot上做了什么？
