.net - Translate this C# comparison to VB.NET -

i'm trying translate comparison between 2 nullable(of byte) objects:

    public byte?[] header { get; private set; }      public override bool equals(object other)     {         // ... more code translate         if (this.header != othertype.header) return false;         // ... more code translate     } 

an online code translator gives me equivalent:

    private m_header nullable(of byte)()     public property header() nullable(of byte)()                     return m_header         end         private set(value nullable(of byte)())             m_header = value         end set     end property      public overrides function equals(other object) boolean          ' ... more code translated         if me.header <> othertype.header             return false         end if         ' ... more code translated      end function 

but exception:

operator '<>' not defined types '1-dimensional array of byte?' , '1-dimensional array of byte?'. use 'is' operator compare 2 reference types.

then, detail of exception says, know if should proper translation 'cause i'm not totally sure:

if not me.header othertype.header     return false end if 

you use null-coalescing operator treat null-byte 0:

public overrides function equals(other object) boolean     ' ... '     dim othertype = trycast(other, actualtype)     if othertype nothing return false     if if(me.header, 0) <> if(othertype.header, 0)         return false     end if     ' ... ' end function 

here approach checks if both nullable-arrays equal:

if header nothing andalso othertype.header nothing     return true elseif object.referenceequals(header, othertype.header)     return true elseif header nothing orelse othertype.header nothing     return false else     return header.sequenceequal(othertype.header) end if
