Question

What is the easiest way to find out how much memory an object uses in .NET?

Preferably without having to resort to a third party tool. Marshal.SizeOf or the sizeof operator look useful but only work with a restricted range of types.

Answer 1

Asked and answered here: Determine how much memory a class uses?

The quick summary is that if you don't want to use a tool, you need to use the .NET Profiling API

The Profiling API is amazingly powerful, but I don't think it would qualify as "easy" by any stretch of the imagination, so I would strongly recommend using a memory profiling tool - there are some free ones that are OK, and some not-too-expensive commercial ones (JetBrains dotTrace in particular) that are really good.

you could also do something like this:

int startMem = GC.GetTotalMemory(true);
YourClass c = new YourClass();
int endMem = GC.GetTotalMemory(true);
int usedMeme = endMem - startMem;
