C#中"this"赋值的示例是什么？

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }

    public void SetName(string name)
    {
        this.Name = name;
    }

    public void SetAge(int age)
    {
        this.Age = age;
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        Person person = new Person();
        person.SetName("John");
        person.SetAge(30);

        Console.WriteLine($"Name: {person.Name}, Age: {person.Age}");
    }
}
