Hi Wrong Syntax : mylist1.Add( NameAgebike );//Multiple data not allowded Correct One : mylist1.Add(Name);// Try this code : using System; using System.Collections.Generic; public class Program { public static void Main() { List string > mylist1 = new List string >(); string name = dinesh ; int age = 16; string bike = Hero ; mylist1.Add(name); mylist1.Add(age.ToString()); mylist1.Add(bike); var listDetails = string .Join(   mylist1); Console.WriteLine(listDetails); } } Demo : https://dotnetfiddle.net/eBn99o

Hi Dinesh You have declared List so you have to add those value one by one. eg: mylist1.Add(name); mylist1.Add(bike); you can't add int type variable to a list as you have declared it as int. If you want to add the all three variables i would recommend you to create a class and add these variables as properties. Eg: Class Rider { public string name {get;set public string bike{get;set public int age{get;set } and than create object of this class and create List class List lstRider=new List (); Rider v=new Rider(); _rider. name=sample; _rider. bike=hero; _rider. age=1; lstRider.Add( _rider); I hope this helps.

As you are printing the whole list in 1 go it will list them in a row. To seperate the list how you want it you need to understand arrays. You need to change this line Console.WriteLine(listDetails); into 2 lines Console.WriteLine(listFirstDetails); //change it to the first 3 fields of your list Console.WriteLine(listLastDetails); //change it to the last 3 fields of your list That would be a quick fix but you need to invest some time in how to print individual items in a list array. Using Classes and breaking your code down into chunks (sub routoines functions) will make your coding faster and easier to debug.

Remember List behaved as a Single-Dimensional Array https://msdn.microsoft.com/en-us/library/6sh2ey19(v=vs.110).aspx
