Answer 1

Unmanaged structures can contain embedded arrays. By default, these embedded array fields are marshaled as a SAFEARRAY. In the following example, s1 is an embedded array that is allocated directly within the structure itself.

Unmanaged representation
struct MyStruct {
    short s1[128];
}

Arrays can be marshaled as UnmanagedType.ByValArray, which requires you to set the MarshalAsAttribute.SizeConst field. The size can be set only as a constant. The following code shows the corresponding managed definition of MyStruct. C#VB

[StructLayout(LayoutKind.Sequential)]
public struct MyStruct {
   [MarshalAs(UnmanagedType.ByValArray, SizeConst=128)] public short[] s1;
}
