Object initializer is one of the new features in C# 3.0 for easy initialization. We will understand this simple feature with examples.
Consider a Student Entity like,
class Student
{
private string FirstName;
private string LastName;
private int Age;
private string City;
}
Traditionally, we will initialize this entity either by instantiating or in the constructor like,
Student stu=new Student();
stu.FirstName="Satheesh";
stu.LastName="Babu";
stu.Age=26;
stu.City="Bangalore";
OR
class Student
{
private string FirstName;
private string LastName;
private int Age;
private string City;
public Student(string _fname,string _lname,int _age,string _city)
{
FirstName=_fname;
LastName=_lname;
Age=_age;
City=_city;
}
}
Student stu=new Student("Satheesh","Babu",26,"Bangalore");
In C# 3.0, this is still simplified and we can do it like,
Student stu=new Student(FirstName="Satheesh",
LastName="Babu",
Age=26,
City="Bangalore");
Likewise, if a member is another object it can be still initialized like,
Student stu=new Student(FirstName="Satheesh",
LastName="Babu",
dob=new DateOfBirth(Day=11,Month=8,Year=1981);
Age=26,
City="Bangalore");
