how to get a field of an IEnumerator with an index

radouane zili

Hello,

Is there a way to get a property of an object in an IEnumerator list with an index ?

Normally , if we have this structure :

Person[] peopleArray = new Person[3]

{

new Person("John", "Smith"),

new Person("Jim", "Johnson"),

new Person("Sue", "Rabon"),

};

People peopleList = new People(peopleArray);

the only way to access to the fileds is by using

foreach (Person p in peopleList)

Console.WriteLine(p.firstName+ " " + p.lastName);

}

so my question is :

how can we access to the field with somtthing like this

foreach (Person p in peopleList)

Console.WriteLine(p[0] + " " + p[1]); ???

}

plz to help

There is no direct way but you can do something like this. You can use reflection but remember, it has it's own performance cost.
consider below example where I have a list of person class with some data and below is the output of the same.
Listlst=new List
{
new Person{firstname="Tapan",lastname="Patel"},
new Person{firstname="C#",lastname=""}
};
foreach(var p in lst)
{
var k=p.GetType().GetProperties();
Console.WriteLine(k[0].GetValue(p)+""+k[1].GetValue(p));
}
//output
//Tapan Patel
//C#
Please mark it as an answer if it addresses the issue.
