Comparision b/w X++ and C#

Hi frnds...


we all know that both X++ and C# are OPP languages, but still there is some Differences in both.... the main differences is ..............

	X++	C#
abstract
class	The modifiers public and private are ignored on class declarations. There is no concept of a namespace grouping of classes. There are no dots (.) in any class names.	The modifiers public and private can be used to modify class declarations. C# also has the keyword internal, which relates to how classes are grouped together in assembly files.
extends	A class declaration can inherit from another class by using the extends keyword.	A colon (:) is used where the key words extends and implements are used in X++.
final	A final method cannot be overridden in a derived class. A final class cannot be extended.	The keyword sealed on a class means the same thing that final means on an X++ class.
implements	A class declaration can implement an interface by using the implements keyword.	(See extends.)
interface	An interface can specify methods that the class must implement.	An interface can specify methods that the class must implement.
new	The new keyword is used to allocate a new instance of a class. Then the constructor is automatically called. Each class has exactly one constructor, and the constructor is named new. You can decide what parameters the constructor should input.	The new keyword is used to create a new instance of a class. Then the constructor is automatically called. Constructor methods themselves are not named new; they have the same name as the class.
null
private and protected	The private and protected keywords can be used to modify the declaration of a class member.	The private and protected keywords can be used to modify the declaration of a class member.
public	A method that is not modified with public, protected, or privatehas the default access level of public.	A method that is not modified with public, protected, or private has the default access level of private.
static	A method can be static, but a field cannot.	Both methods and fields can be static.
super	The super keyword is used in a derived class to access the same method on its base class. void method2() { ; // Call method2 method // on the base class. super(); }	The base keyword is used in a derived class to access various methods in its base class. void method2() { // Call methods on // the base class. base.method2(); base.method3(); }
this	For a call from one instance method to another on the same object, a qualifier for the called method is required. The keyword this is available as a qualifier for the current object.	For a call from one instance method to another on the same object, a qualifier for the called method is not required. However, the this keyword is available as a qualifier for the current object. In practice, the keyword this can be helpful by displaying IntelliSense information.
finalize	The Object class contains the finalize method. The finalize method is not final, and it can be overridden. The finalize method appears to resemble the System.Object.Finalize method in C#, but in X++ the finalize method has no special meaning of any kind. An object is automatically removed from memory when the last reference to the object stops referencing the object. For example, this can happen when the last reference goes out of scope or is assigned another object to reference.	The methods Finalize and Dispose are common on some types of classes. The garbage collector calls the Finalize and Dispose methods when it destroys and object.
main	Classes that are invoked from a menu have their main method called by the system.	Classes that are invoked from a command line console have their Main method called by the system.
