描述勘误

[PSC-F]

• 区别于只读属性
  与只读属性不同，Init only setters 的值可以在对象初始化之后更改。以下是一个示例：[勘误：这里不可以修改]

public class Person
{
    public string FirstName { get; init; }
    public string LastName { get; init; }
    public string FullName => $"{FirstName} {LastName}";
}

var person = new Person
{
    FirstName = "John",
    LastName = "Doe"
};

Console.WriteLine(person.FullName); // Output: John Doe

person.FirstName = "Jane";
person.LastName = "Doe";

Console.WriteLine(person.FullName); // Output: Jane Doe
