Types of Constructor in .Net

Constructor is nothing but a function (with the same name as Class) and is used for initializing the members of a class whenever an class object is created. You can initialize the members with any value (as per member datatype) or with the default values through constructor.

If a class is not defined with the constructor then the CLR (Common Language Runtime) will provide an implicit constructor which is called as Default Constructor.
A class can have any number of constructors provided they vary with the number of arguments that are passed, which is they should have different signatures.

Some of the basic properties of Constructor are :
a. Constructors do not return a value.
b. Constructors can be overloaded.
c. If a class is defined with static and Non-static constructors then the privilege will be given to the Non-static constructors.
