C#语法糖

最近看到代码中有语法糖，记录一下，

1.重写，只能重写，属性，虚方法（virtual）,子类重写用override

private string a
public string A
{
get =>“123”；
set =>a=value;
}

2.定义静态变量赋值
private static Lazy<KafkaProducer> Producer { get; } = new Lazy<KafkaProducer>(() => new KafkaProducer(_kafkaConfigDic), true);

静态属性，类初始化就会执行

3.给引用的对象区别名
using Common.Logging;
using Tuhu.WinService.ConsumerForPush.Kafka;
using System;
using System.Threading.Tasks;
using KafkaMessage = Confluent.Kafka.Message<Confluent.Kafka.Null, string>;
