About Sort by List Elements (OrderBy) and Assign Any Number

Let's take turns cleaning up each item.

Let's start with the first condition.Let's sort out what list items you have and how you want the list to be displayed to users.
This time, the list has a list of people, and each list item is

• Age
• Last name
• Name
• Number of fruits

You have indicated that you would like to have .
The way you hold your data is smart enough to manage them as classes and structures.

It's the second one.If you want to use OrderBy when sorting lists, the argument specifies a lambda expression to get the key to sort.The image is that all the elements in the list are converted into a given lambda formula and sorted by the result.However, this is the that sorts the original list, not the original list itself. If you want to sort the list itself, there is a method called Sort if it is in the List<T> class.

And about the third fruit distribution."This time, regardless of the type of fruit, they simply wanted to equalize the number as much as possible."And I heard that the remaining amount will be distributed from the younger people in order.
If so,

// The number of fruits to distribute equally to everyone.The C# specification truncates the decimal portion of the result when divided by integers.
var fruitsDiv =nrOfFruits/peopleList.Count;
// The number of fruits left over, that is, the number of people who can get one more fruit.
var fruitsMod =nrOfFruits%peopleList.Count;

// PeopleList is a list of people sorted by age.
// Suppose you have a property called FruitCount to remember the number of fruits.
for (vari=0;i<peopleList.Count;i++)
{
    // Only young people to fruitsMod distribute fruitsDiv and one more.
    if(i<fruitMod)
    {
        peopleList[i].FruitsCount=fruitsDiv+1;
    }
    else
    {
        peopleList[i].FruitsCount=fruitsDiv;
    }
}

It would be a good idea to do something like that

By the way, the part of orderedNames becomes System.Linq.orderedEnumerable... because orderedNames has been implicitly converted into a string.By default, the passed object has
The value returned by the ToString method is included there.If you extend ToString when you create your own class, you are free to rewrite this conversion result.A simple listing might do this without creating a template, but if you want to control more complex viewing, you might want to learn more about the WPF template or ask another question.

Is it smarter to have a multi-dimensional array by name and age?

Data structures should be defined in classes or structures for easy access.

public class Person
    {
        public string FirstName {get;set;}
        public string LastName {get;set;}
        public int Age {get;set;}
        public int fruits {get;set;}
    }

The OrderBy argument specifies a function that extracts the key to be sorted from the element.In the example below, it is described in lambda formula.

private void SortAndDistributeFruits (List<Person>persons, int fruits)
    {
        // Sort by age
        var orderedPersons=persons.OrderBy(e=>e.age).ToList();

        // distribute one by one until the fruit is gone in the loop
        for (inti=0; i<fruit;i++)
        {
            // divide by the number of people to decide who to distribute
            var index = i%orderedPersons.Count;

            // hand out one
            orderedPersons [index].Fruits++;
        }
    }

The list returned by OederBy is different from the original list.If you want to change the order of the original list itself, you can also use the Sort method.
