Visual studio 获取visual studio ultimate“；“调试托管内存”；windbg的输出

是否可以在WINDBG中获取堆上托管对象的摘要信息，该信息类似于Visual Studio Ultimate的“调试托管内存”选项提供的摘要

我可以获得一些信息，但这是一个个案的基础上，是相当乏味的。 是否有一个宏或一组命令可以使用WINDBG生成类似的输出

---

Visual Studio似乎有一个简洁的小例程，它收集所有根并显示根对象类及其总内存的摘要。

这些将为您提供特定类型的托管内存、堆摘要和堆消耗，以防您试图在堆上查找字符串：

!EEHeap
!DumpHeap -stat 
!DumpHeap -strings 
!DumpHeap -Type <TypeSpec> 

有关更多信息，请参阅。

sosex是另一个扩展，但我没有用它来调试泄漏。与Windbg IMHO相比，CLRProfiler和Visual Studio Standalone Profiler是调试这些问题的最佳工具。

与任何.NET问题一样，您首先需要SOS扩展

.loadby sos clr; .loadby sos mscorwks

然后，您可以使用

!dumpheap -stat; * Statistics output, good if you don't know what you're looking for
!dumpheap -type <SubstringOfClass>; * If you know what type you're after
!dumpheap -mt <MethodTable>; * If the class substring is not unique enough

示例演练：

0:005> !gcroot -all 0000000002594848

因此，这个对象似乎没有更多的引用，将在下一次GC期间被垃圾收集
