I have a class it contains some string members, some double members and some array objects.
I create two objects of this class, is there any simplest, efficient way
Since these are objects my guess is that you will have to override the Equals method for objects. Otherwise the Equals method will give you ok only if both objects refering to the same object.
I know this is not the answer you want. But since there is little number of properties in your class you can easily override the method.
