How can I check if a given address is 32-bit or 64-bit?

Time：10-24

How can I check if the address value in a long variable is 32bit or 64bit

Example:

long a = 0x06000000
long b = 0x13FFF0000

How can I programmatically check the bitness of these addresses?

CodePudding user response：

You can use an AND operation to check if any of the higher 32 bits are set. Assuming that you have ulong because addresses are not negative:

if ((x & 0xFFFFFFFF00000000UL) == 0)
    Console.WriteLine("x would fit into 32 bit");
