Unity 使用this关键字进行函数拓展 - DateTime
【摘要】
Example：
using System;using UnityEngine; using SK.Framework; public class Foo : MonoBehaviour{ private void Start() { DateTime dt = DateTime.Now; /...
Example：
-
using System;
-
using UnityEngine;
-
-
using SK.Framework;
-
-
public class Foo : MonoBehaviour
-
{
-
private void Start()
-
{
-
DateTime dt = DateTime.Now;
-
-
//周六
-
dt.DayOfWeek.ToChinese();
-
//星期六
-
dt.DayOfWeek.ToChinese2();
-
-
//yyyy/MM/dd
-
dt.ToDateString();
-
//yyyy-MM-dd
-
dt.ToDateString2();
-
//yyyy年MM月dd日
-
dt.ToDateString3();
-
-
//yyyy/MM/dd HH:mm:ss
-
dt.ToDateTimeString();
-
//yyyy-MM-dd HH:mm:ss
-
dt.ToDateTimeString2();
-
//yyyy年MM月dd日 HH:mm:ss
-
dt.ToDateTimeString3();
-
}
-
}
