Solution 2

By default, the Equals method works in one of two ways:

For Value types it does a bit wise comparison: checking if the two object contents are the same.
For Reference types, it compares the references: if they are the same the objects are the same and there is no need to look at the content.

This behaviour can be overridden in derived classes (and is, for example, the String class is a Reference type which overrides the Equals method to do a byte-by-byte comparison of the two strings).

i just go with object class by using go definition from my class to know how base class is formed. In that it just has been written as a one line word(public virtual bool Equal(Object obj)).But i dont know where this bitwise process have been written?

Sorry, but I don't understand you.
Could you try writing that a bit longer in your native language and run it though google translate to see if that helps?

If you really want to know the fine detail at that low a level, go and have a look at MONO - the source is available for browsing (.NET source is proprietary to Microsoft) and does the same thing.

Just look it up:
http://docs.oracle.com/javase/1.4.2/docs/api/java/lang/Object.html#equals%28java.lang.Object%29[^]
