C# .NET - 有没有办法在运行时确定我的应用程序的每个类/对象类型的内存使用情况？

Question

I have a C# .NET app running in the cloud (Heroku) and from time to time I'm experiencing memory leaks.

I would like to get a detailed memory usage statistics from my app, in runtime, because I cannot attach a debugger to the remote process.

It would be great if I could get something like the follwing from inside of my C# code during runtime:

> dumpheap -stat

Statistics:
              MT    Count    TotalSize Class Name
...
00007f6c1eeefba8      576        59904 System.Reflection.RuntimeMethodInfo

I was unable to find anything so far, neither of: a free library, a third party tool nor a code snippet.

You can use DotMemory . This tool will show you memory leak suggestion, total memory, memory of each type object...
