C# Serializable Keyword
What is the use of serializable keyword in C#?
kirangiet
- Jun 8th, 2010
We usually serialize the object, which we are transferring across processes.Example: When we are using Out Proc session Management we should add the serializable attribute at the top of the class.e.g.[Serializable]public Class Employee{public string Name;public int Age;}

Advantage of Generic:-
1. Generics provide type safety without the overhead of multiple implementations.
Ex. We can create a linked list of string.
LinkedList<string>linkList=new LinkedList<string>();
There is no need to inherit from a base type and override members.The linked list is ready
for immediate use.
2. There is no need to write code to test for the correct data type because it is enforced
at compile time. The need for type casting and the possibility of run-time errors are
reduced.
3. Generic collection types generally perform better for storing and manipulating value
types because there is no need to box the value types.
4. Generic delegates enable type-safe callbacks without the need to create multiple delegate
classes.
5.Generic delegates can also be used in dynamically generated code without requiring the
generation of a delegate type. This increases the number of scenarios in which you can use
lightweight dynamic methods instead of generating entire assemblies.
Advantage of Delegate:
Delegates are managed function pointers. they are type checked and held in spaces that can
be reclaimed by the memory manager.chintan.desai

Adding on sutanu_halder answer: 1. Delegate executes asynchronousely, while Generice execute synchronousely. 2. Delegate is not type safe. We can define anonymous method which can execute without creating delegate object in memory. Generic is type-safe.

The 'this' keyword in C# is used to reference the current class instance.
It can be optionally used as a qualifier in referencing the fields, properties or methods of the current instance of the class.chintan.desai

If a base class has a bunch of overloaded constructors, and an inherited class has another bunch of overloaded constructors, can you enforce a call from an inherited constructor to an arbitrary base constructor?
Yes, just place a colon, and then keyword base (parameter list to invoke the appropriate constructor) in the overloaded constructor definition inside the inherited class.
