[StructLayout (LayoutKind. explicit)] public class AA {[FieldOffset (0)] public readonly Int16 m_x = 55; [FieldOffset (0)] public readonly Byte m_ B = (Byte) 22 ;}

AA m = new AA (); var d1 = m. m_ B; var d2 = m. m_x;

Output value:

Field definition Exchange Order:

[StructLayout (LayoutKind. explicit)] public class AA {[FieldOffset (0)] public readonly Byte m_ B = (Byte) 22; [FieldOffset (0)] public readonly Int16 m_x = 55 ;}

 

 

For the same offset, the output value is based on the value of the last field.

CLR maintains the sequence of fields defined by developers.
