C# 属性

Code

namespace ConsoleApp
{
    public class Cat
    {
        public string Name1 { get; set; } = "mimi";
        public string Name2 = "mimi";

        public string Name3 { get { return "mimi"; } }
        public string Name4 { get; } = "mimi";
        public string Name5 => "mimi";
    }
}

1、2一样，可以get set
3、4、5一样，都是只读属性，只不过是语言版本不同的写法
