Hi Folks , Today I am talking about Object Initializer Object initializer
is a new language enhancements of C# 3.0.This helps to initialize the initial
value to the specified data member(s) of the newly created object or
collection in a single step , {} braces used to initialize the data members
as below
using System;
using System.Collections.Generic;
using System.Text;
using System.Query;
using System.Xml.XLinq;
using System.Data.DLinq;
namespace Object_Initializers
{
class Employee
{
public int EmpNo;
public string EmpName;
static void Main(string[] args)
{
Employee empObj = new Employee{EmpNo = 1,EmpName="Anand"};
Console.WriteLine("The Emp No # {0} Emp Name #
{1}",empObj.EmpNo,empObj.EmpName);
Console.ReadLine();
}
}
}
This is equals to invoke a instance constructor and assign value to each
field . Each member initializer assigns a value to a field or property of the
object . the object initialize applicable to collection class as well .The
process of initialize the collection object is similar to the above code .
List<string> listObj = new List<string> {"UG Hyderabad","UG Bangalore","UG
Chennai","UG Mumbai"};
foreach ( string s in listOobj)
Console.WriteLine(s);
Few points you must keep in mind while using the object initializer 1.
The Member initializer must be a field or property (set property) of the
object
2. You can not initialize multiple values to the same field or property
3. The initializer applies to the collection of type
System.Collections.Generic.ICollection<T>
