Question

I want to know what this following level mean in VB
<StructLayout(LayoutKind.Sequential, CharSet:=CharSet.Ansi)> _

And i want the statement equivalent to this in vc++.

I am in a process of converting the VB code to vc++.
I am done with everything except this part.

It means that the fields of the class should be laid out sequentially (i.e. in the order that they're declared) according to the 'pack' size. This prevents the CLR from re-arranging the fields which it may do for efficiency reasons and which you certainly don't want when inter-operating with unmanaged code. The equivalent in C++/CLI is: [StructLayout(LayoutKind::Sequential CharSet = CharSet::CharSet.Ansi)]
