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

1. public class Program
2. {
3. public static void Main()
4. {
5. List<string> mylist1 = new List<string>();
6. string name = "dinesh";
7. int age = 16;
8. string bike = "Hero";
9. string name1 = "X";
10. int age1 = 15;
11. string bike1 = "Honda";
13. mylist1.Add(name);
14. mylist1.Add(age.ToString());
15. mylist1.Add(bike);
16. mylist1.Add(name1);
17. mylist1.Add(age1.ToString());
18. mylist1.Add(bike1);
19. var listDetails = string.Join(",", mylist1);
20. Console.WriteLine(listDetails);
21. }
22. }
o/p is:
dinesh,16,Hero,X,15,Honda
I want o/p like this:
{dinesh,16,Hero}
{X,15,Honda}

Hi,

Wrong Syntax :

mylist1.Add(Name,Age,bike);//Multiple data not allowded

Correct One :

mylist1.Add(Name);//

Try this code :

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.
