marshal to a Variable length Array

Question

 Hi ,

I am getting  data from a file in binary format ,  which should be de-serialize to a  a different  Structs .

 Desierilazation is work fine if the struct contain  fixed length array by providing  

 ex: [MarshalAs(UnmanagedType.ByValArray, SizeConst = 8)].

But I have to de-serialize to a struct contain  variable length array whose size is determined based on the pointer .

The struct is provided here ...

public struct  DL_BITMAP 
{

     public int lOrgX;
    public int lOrgY;
    public int lWidth;
    public int lHeight;
    public uint dwFlag;
    public uint rgbPixel;
     public byte[] lPixel;
}

Upon de-serializing  the  the public byte[] lPixel  contain only one value .

Is there any way to  marshal to variable length array .

How the CustomMarshaller  is implemented
