int double datetime data type is class or structure

int double datetime data type class or structure in dotnet?

how , how memory allocated data type?

thanks

actually in case of c# size of int , double defined, int int32 in c#, double double(double precison float, i.e.: 64-bit float) effort on making 32 64-bit porting of code easier. (c# designed when there 64-bit cpus were made there goal make transition possible)

for datetime since it's struct, size dependent on implementation. size uint64 + size of it's method there's no restriction on whether new internal structure added in later versions.
