How to set c# struct attribute (StructLayoutAttribute) globally?

Question

I'm working on a c# p/invoke project and defining a lot of structures. For each structure, I'm using:

    [System.Runtime.InteropServices.StructLayoutAttribute(System.Runtime.InteropServices.LayoutKind.Sequential, Pack = 1)]

But Now I'd like to set the attribute(Pack = 1) only once so that all my structures share the same setting, How can I do that?

Thanks, Fei

You cannot do that. There is no global switch. You have to set Pack explicitly on every struct.

You can at least make you code more concise by adding a using statement, and by writing StructLayout rather than StructLayoutAttribute:

using System.Runtime.InteropServices;

....
[StructLayout(LayoutKind.Sequential, Pack = 1)]
