how to get a field of an IEnumerator with an index

Question

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. List lst= 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.
