Yes, we can we existing List<T>[List is a collection] also we can use with custom types like student,person,employee............ect
Ex:
public class Student
{
private string _Name;
private int _Age;
public string Name
{
get{return _Name;}
set{_Name = value;}
}
public int Age
{
get{return _Age;}
set{_Age = value;}
}
}
this is my custom type is called Student. Now i want to perpare a collection like premetive types.yes we can prepares studentscollection here is Stulist
static void Main(string[] args)
{
List<Student> Stulist = new List<Student>();
Student P1 = new Student();
P1.Age = 25;
P1.Name = "anand";
Stulist.Add(P1);
Student P2 = new Student();
P2.Age = 26;
P2.Name = "balu";
Stulist.Add(P2);
IEnumerator<Student> ierStudent = Stulist.GetEnumerator();
while (ierStudent.MoveNext())
{
Student p = ierStudent.Current;
Console.Write("Student name : "+p.Name + " Age : " + p.Age+"\n");
}
Console.ReadKey();
}
Now we have to keep in mind one point is
Ex:
public class Student
{
private string _Name;
private int _Age;
public string Name
{
get{return _Name;}
set{_Name = value;}
}
public int Age
{
get{return _Age;}
set{_Age = value;}
}
}
this is my custom type is called Student. Now i want to perpare a collection like premetive types.yes we can prepares studentscollection here is Stulist
static void Main(string[] args)
{
List<Student> Stulist = new List<Student>();
Student P1 = new Student();
P1.Age = 25;
P1.Name = "anand";
Stulist.Add(P1);
Student P2 = new Student();
P2.Age = 26;
P2.Name = "balu";
Stulist.Add(P2);
IEnumerator<Student> ierStudent = Stulist.GetEnumerator();
while (ierStudent.MoveNext())
{
Student p = ierStudent.Current;
Console.Write("Student name : "+p.Name + " Age : " + p.Age+"\n");
}
Console.ReadKey();
}
Now we have to keep in mind one point is
NOTE:
Class List<T>:IEnumerable<T>
{
}
We no need to implement IEnmerable interface by the Person type. why because List<T> collection[generic class] implements IEnumerable<T> interface. But If we use our own collection like may be studentscollection then it has to implement the IEnumerable interface to iterate through the members.
