Contrary to the current most popular answer, shorter integers (like Int16 and SByte) do often times take up less space in memory than larger integers (like Int32 and Int64). You can easily verify this by instantiating large arrays of sbyte/short/int/long and using perfmon to measure managed heap sizes. rodas ffwd
