c# - SuppressUnmanagedCodeSecurity or SuppressUnmanagedCodeSecurityAttribute? -

to disable security checks should set? suppressunmanagedcodesecurityattribute or suppressunmanagedcodesecurity?

which of these versions corrrect?

    [dllimport("native.dll"), suppressunmanagedcodesecurity]     public static extern void method(... 

or

    [dllimport("native.dll"), suppressunmanagedcodesecurityattribute]     public static extern void method(... 

both same thing. class named suppressunmanagedcodesecurityattribute, when annotating attributes in general, can omit suffix attribute.
