C#語法糖

最近看到代碼中有語法糖，記錄一下，

1.重寫，只能重寫，屬性，虛方法（virtual）,子類重寫用override

private string a
public string A
{
get =>「123」；
set =>a=value;
}

2.定義靜態變量賦值
private static Lazy<KafkaProducer> Producer { get; } = new Lazy<KafkaProducer>(() => new KafkaProducer(_kafkaConfigDic), true);

靜態屬性，類初始化就會執行

3.給引用的對象區別名
using Common.Logging;
using Tuhu.WinService.ConsumerForPush.Kafka;
using System;
using System.Threading.Tasks;
using KafkaMessage = Confluent.Kafka.Message<Confluent.Kafka.Null, string>;
