Constructor in C Sharp

In C#, Constructors are the special types of methods of a class which get executed when it's object is created. Constructors are responsible for object initialization and memory allocation of its class. There is always at least one constructor in every class. If you don't write a constructor in class, C# compiler will automatically provide one constructor for that class.

C Sharp Delegates and Plug-in Methods with Delegates

Delegate is a reference type that holds the reference of a class method. Any method which has the same signature as delegate can be assigned to delegate. Delegate is like function pointer in C++. There are three aspects to a delegate: Declaration, Instantiation and Invocation.

C Sharp Generic delegates Func, Action and Predicate with anonymous method

In .net 3.5 some new generic delegates -Func<T>, Action<T> and Predicate<T> were introduced. Using generic delegates, it is possible to concise delegate type means you don’t have to define the delegate statement. These delegates are the Func<T>, Action<T> and Predicate<T> delegates and defined in the System namespace.

C Sharp Extension method

An extension method is a static method of a static class that can be invoked using the instance method syntax. Extension methods are used to add new behaviors to an existing type without altering. In extension method "this" keyword is used with the first parameter and the type of the first parameter will be the type that is extended by extension method.

C Sharp Anonymous Method

The concept of anonymous method was introduced in C# 2.0. An anonymous method is inline unnamed method in the code. It is created using the delegate keyword and doesn’t required name and return type. Hence we can say, an anonymous method has only body without name, optional parameters and return type.

C Sharp Lamda Expression

The concept of lamda expression was introduced in C# 3.0. Basically, Lamda expression is a more concise syntax of anonymous method. It is just a new way to write anonymous methods. At compile time all the lamda expressions are converted into anonymous methods according to lamda expression conversion rules.

C Sharp Var data type and Anonymous Type

var data type was introduced in C# 3.0. var is used to declare implicitly typed local variable means it tells the compiler to figure out the type of the variable at compilation time. A var variable must be initialized at the time of declaration.

Introduction to C Sharp

C# is developed by microsoft and comes after C, C++, Java. It inherits the properties of C, C++, Java, VB. We can say C# is smart and intelligent sister of Java because it do work smartly.
