change offset of an IntPtr

[Vahid_Keyany]

hi

i have a structure from unmanaged code that have two member
for a string value inside structure buffer (stringOffset, stringSize)
i have convert my structure to an IntPtr value with Marshal.StructureToPtr.

now , i want extract string value inside structure buffer , i must use
Marshal.PtrToString method but there is a problem.
how i can forward IntPtr value to string value offset ?
is there any way to change offset of an IntPtr value ?

thanks

i think this is true :

IntPtr strptr = new IntPtr(structptr.ToInt32() + struct.stringOffset);
