C#: How much RAM does an object with all sub-objects need? Get list of needed RAM for object?

Question

Hello,

is there a way to get, for debuging purpose, a list of needed RAM for all my objects incl. sub-objects and so on, written to a text-file?

I need to get these values while running in production mode without visual studio running. For example every x minutes. Is this possible? How can I do that?

Thank you very much in advance,

Chris

Answer 1

You can create a tool, that will monitor size of process.
Or do this in seperate thread of running application. Process.GetProcessesByName()...

Answer 2

For value types, you should be able to use sizeof(). I don't think there is an equivalent for reference types, though. Note you can only use sizeof() inside an unsafe block.

Answer 3

Load windbg and load sos.dll, and attach to process.

log the output to a file then do a !DumpHeap -stat (and variants)

psscor2.dll can dump the heap to an xml file. (or one for use with ClrProfiler)

Answer 4

You can use JetBrains DotTrace to do the memory profiling. Its only 30 days trial but what a great tool to navigate through specific in-memory objects.
