Question

Why we use Constructor in C#? What are the advantages of Constructor?

Sujeet Suman · Answer

Ujjval c onstructors are the special types of methods of a class which get executed when it's object is created. The main purpose of constructor is below: (01.) To initialization class object. (02.) To allocate memory for class. (03.) To initialize data member of class. (04.) To prevent a class initialization by using private constructor. (05.) To initialize static data member of class by using static constructor. Unless the class is static classes without constructors are given a public default constructor by the C# compiler in order to enable class instantiation.

Hi, Initialization of values of different variables is critical in any application development. C# does initialize simple data-types to default values as per the language specification in the .Net framework, but for classes that are user specific, it is obvious that you would be the only one who can decide what is an ideal default value. The means of achieving this is Constructors. There is also a perception that constructors can only be used beyond initialization, which is true to some extent.
