.Net 内存转储：!eeheap -gc：GC 生成从哪里开始和结束？
我认为我在这里遗漏了一些基础知识，所以希望这篇文章可以澄清这一点。
我已经进行了转储，正在查看托管堆，并且有兴趣专门查看每个堆中的对象。 以下是调试器的输出：

我希望能够获取 GC 各代的起始地址，然后查看从该地址开始一直到下一代的段。 我相信堆被压缩，因此期望在第一段找到第 2 代，情况似乎是这样：
01650000 01651000 0264fcc8 0x00ffecc8(16772296)
但是我无法确定它的结束位置，因为我无法找到第 1 代从 开始的位置0x3cc9d8a0。
我认为我在这里遗漏了上述解决方案的一些基本原理。
有什么建议么？
I think I'm missing some fundamentals here so hopefully this post can clarify this.
I've taken a dump and am looking at the managed heap and am interested in looking specifically at what objects are within each heap. Here is the output from the debugger:
0:000> !eeheap -gc

------------------------------
GC Heap Size 0x21997e04(563707396)
I expect that I can take the start address of the GC generations and then look at the segments that start from that address all the way up to the next generation. I believe the heap is compacted thus expect to find generation 2 at the first segment, and this looks to be the case:
01650000 01651000 0264fcc8 0x00ffecc8(16772296)
However I'm not able to determine where this ends as I can't find where generation 1 starts at 0x3cc9d8a0.
I think there are some fundamentals of the above addressing that I'm missing here.
Any suggestions?

您可以使用 SOSEX 扩展来单独检查每个代堆，并查看每个代堆的根每个堆上的对象。
You can use the SOSEX extensions to examine each generations heap individually and also look at the roots of each object on each heap.
