Find out process bitness programmatically [duplicate]

Question

This question already has an answer here:

• How to determine programmatically whether a particular process is 32-bit or 64-bit 7 answers

Is there anyway I can find out if my .NET process is running as 32bit process or 64bit process?

Answer 1

You probably want Environment.Is64BitProcess if you're using .NET 4.0 or later. Otherwise, check IntPtr.Size , as suggested in the other answers.

Answer 2

if (IntPtr.Size == 4)
    // 32-bit

else if (IntPtr.Size == 8)
    // 64-bit

From this question

However, as pointed by @Jim Mischel, on .NET 4 and above, you should use

Environment.Is64BitProcess

Answer 3

Use IntPtr.Size property to find out process bitness.

if(IntPtr.Size == 4)
 // 32 bit process
else
 // 64bit process
