C#6.0新特性

1、自动属性增强

1.1、自动属性初始化与只读属性初始化

public class Person
    {
        public string Name { get; set; } = "sandy";
        public int Age { get; } = 20;
    }

2、用Lambda作为函数体 (Expression bodies on method-like members)

    public class Person
    {
        public string FirstName { get; set; }

        public string LastName { get; set; }

        public override string ToString() => string.Format("{0}——{1}", FirstName, LastName);

    }

3、Lambda表达式用作属性 (Expression bodies on property-like function members)

 public class Person
    {
        public string FirstName { get; set; }

        public string LastName { get; set; }

        public string FullName => FirstName + " " + LastName;
    }

4、字符串嵌入值 (String interpolation)

 public class Person
    {
        public string FirstName { get; set; }

        public string LastName { get; set; }

        public string FullName =>$"{FirstName } {LastName }";
        //上这两句等价
        public string fName => string.Format("{0} {1}", FirstName, LastName);
    }
    class Program
    {
        static void Main(string[] args)
        {
            Person p = new Person();
            p.FirstName = "a";
            p.LastName = "b";
            Console.WriteLine(p.FullName);
            Console.WriteLine(string.Format($"FirstName is {p.FirstName}"));
            //等价于如下
            Console.WriteLine(string.Format("FirstName is {0}", p.FirstName));
        }
    }

其他新特性以后在补充了。

所有不带着问题的努力，都是瞎忙
