Using C#, how to get whether my machine is 64bit or 32bit?

Question

Using C#, I would like to create a method that retunrs whether my machine is 64 or 32-bit.

Is there anybody who knows how to do that?

Answer 1

You can check using IntPtr size. IntPtr size is 4 for 32 bit OS and 8 for 64 bit OS

/// 
Is64s the bit operating system.
/// 
if (IntPtr.Size == 8)
    // 64Bit
else
    // 32bit

Type: System.Int32

The size of a pointer or handle in this process, measured in bytes. The value of this property is 4 in a 32-bit process, and 8 in a 64-bit process. You can define the process type by setting the /platform switch when you compile your code with the C# and Visual Basic compilers.
