How to determine size of .NET managed object in memory (like a sizeof for reference types)http://blogs.msdn.com/mab/archive/2006/04/24/582666.aspxAn approximate way to determine the size of object usage in memory can be done by checking the total memory before and after the creation of the object. In the following example it is assumed you have a class named foo. long StopBytes = 0; foo myFoo;en-USCommunityServer 2.1 SP1 (Build: 61025.2)re: How to determine size of object in memory (like a sizeof for reference types)http://blogs.msdn.com/mab/archive/2006/04/24/582666.aspx#582754Tue, 25 Apr 2006 09:36:21 GMT91d46819-8472-40ad-a661-2c78acb4018c:582754ernowI like this solution but it isn't very threadsafe... <br> <br>When another thread allocates (or worse causes the release of) memory your calculation might go wrong and give you the impression that the object has a negative size...
