How to change variable value depending on architecture

Question

Title is clear: how can I change a value in C# depending on destination architecture? In particular, I want to change a string depending on x86 or x64. Many Thanks!

Edit: I need to check if an x64 Office version is installed if my application is x64 too.

No, question and title are not clear. Change a string from what to what? — H H, Jul 17 '13 at 21:14
What do you want to do if you're running on a 32-bit CLR but on an x64 processor? — Jon Skeet, Jul 17 '13 at 21:20
Ok, Thanks! `Environment.Is64BitProcess` works. I didn't know there were such a simple possibility to "read" that. Thank you again. — LivingSilver94, Jul 17 '13 at 21:23

This should get you what you're looking for:

 string platform = IntPtr.Size == 4 ? "x86" : "x64";

You can use IntPtr.Size

string foobar = String.Empty;

if (IntPtr.Size == 4) //32-bit
    foobar = "foo";
else if (IntPtr.Size == 8) //64-bit
    foobar = "bar";

Environment.Is64BitProcess should do the trick

The simplest way. I'm a newbie, APIs are still not well known to me. – LivingSilver94 Jul 17 '13 at 21:30
