wrap C ++ function in c # that returns pointer

I have the following C ++ function and I would make the wrapper function in c #:

byte* FunctionReturnVectorPoint()
{
   return vectorPoint;
}

I tried so:

[DllImport("DLL_NAME.dll", CallingConvention = CallingConvention.ThisCall)]
unsafe public static extern byte*[] FunctionReturnVectorPoint();

but it does not work.

You have any suggestions?

solved:

[DllImport("DLL_NAME.dll", CallingConvention = CallingConvention.ThisCall)]
public static extern IntPtr FunctionReturnVectorPoint();

and calling the function in this way:

IntPtr tempPoint = FunctionReturnVectorPoint();
byte[] vector= new byte[dimensionVector];
Marshal.Copy(tempPoint , vector, 0, dimensionVector);
