WebOct 20, 2012 · int is always 32bit in C#. internally, the references are using 32bit or 64bit, depending, what kind of process/CPU you have. That means, that structures/classes can be different in size, depending on the process on which your C#-program is running. BUT an int variable is always 32 bit. WebDec 12, 2016 · Process on a 64-bit CPU can work with a larger set of data compared to 32-bit CPU (only constrained by physical memory). A 64 bit integer makes arithmetic or logical operations using 64 bit types such as C#’s long faster than one implemented as two 32 bit operations. To summarize, for all practical purposes…
