c# - 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.

Answer 1

这应该可以为您提供所需的内容：

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

Answer 2

Environment.Is64BitProcess应该做的伎俩

Answer 3

您可以使用 IntPtr.Size

string foobar = String.Empty;

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