与非默认构造函数一起使用
你可以将对象初始值设定项与构造函数结合使用,以在必要时初始化类型以一个如此定义的类为例:
public class Book {
public string Title { get; set; }
public string Author { get; set; }
public Book(int id) {
//do things
}
// the rest of class definition
}
var someBook = new Book(16) { Title = "Don Quixote", Author = "Miguel de Cervantes" }
这将首先使用 Book(int)
构造函数实例化 Book
,然后在初始化程序中设置每个属性。它相当于:
var someBook = new Book(16);
someBook.Title = "Don Quixote";
someBook.Author = "Miguel de Cervantes";
