Size of an objectHi, is there an easy way to know how much memory an instance of an object
takes? I mean, there is the sizeof(type), but this is not what I want... the sizeof(type) returns the size of all the members of the class, but if the class contains reference types like a collection or a string, it can't tell... What I need to know is, if there is a collection of strings, with each strings taking 100kb and having 5 strings in the collection, I want to have 500kb (or approx) as a return... is there an easy, thread-safe way? Thanks ThunderMusic btw, I'm using c# with framework 2.0 Hi,

No, you have no way to know how "big" an object is if you take into account the references it can hold (or the references those referenced instnaces can hold) -- Ignacio Machin machin AT laceupsolutions com ThunderMusic wrote:

There is no way to get a definite size, though. Take a simple examle: string a = new String('*', 5000); string b = a; If you look at each variable, it uses around 10000 bytes, but if you look at them together, they don't use 20000 bytes in total. So, which of them is it that is using the memory?  |
