Question

Sure, here is how to sort a class list by integer property in C#:
C#
class Person {
    public int Age { get; set; }
}
Listandlt;Person> people = new Listandlt;Person>();
people.Add(new Person { Age = 10 });
people.Add(new Person { Age = 20 });
people.Add(new Person { Age = 30 });
// Sort the list by the Age property.
people.Sort(delegate (Person p1, Person p2) {
    return p1.Age - p2.Age;
});
In this example, we first create a class called Person with an integer property called
Age. We then create a list of Person objects and add three objects to the list. The first object has an age of 10, the second object has an age of 20, and the third object has an age of 30.
Next, we use the Sort() method to sort the list by the Age property. The
Sort() method takes a delegate as its parameter. The delegate is a function that takes two objects of the same type and returns an integer. In this case, the delegate compares the ages of the two objects and returns the difference.
The Sort() method will sort the list in ascending order by default. If you want to sort the list in descending order, you can pass
true as the second parameter to the Sort() method.
