unity 的一些方便使用的方法

两个数组的比较是否相同
int[] a,int[]b
Enumerable.SequenceEqual(a,b)

数组转List ： List list = new List(arr);
list转数组：int[] arr = list.ToArray();
将整数num转为16位二进制数组：Convert.ToString(num, 2).PadLeft(16,‘0’);
将字符串进行反向排列:string reverseStr = new string(str.Reverse().ToArray());

string.TrimStrart()// 删除字符串头部的空格
string.TrimEnd()//删除字符串尾部的空格
string.Trim()//删除字符串头部和尾部的空格

多种字符来分割字符串
string str=“我#是%字,符_串”
char[]splits={‘#’,‘%’,‘,’,‘_’};
string[] splitStrs=str.Split(splits);
for(int i=0;i<splitStrs.Length,i++)
{
Debug.Log(splitStrs[i]);
}

字符串截取
str.Substring(2,3);从索引2开始截取3个字符

//获取当前时间戳
long unixTime = ConvertDateTimep(DateTime.Now);
Debug.Log(unixTime);
//将时间戳转换为DateTime
Debug.Log(GetTime(unixTime.ToString()).ToString());

    Debug.Log(GetTime(unixTime.ToString()).Year);
    Debug.Log(GetTime(unixTime.ToString()).Month);
    Debug.Log(GetTime(unixTime.ToString()).Day);
    Debug.Log(GetTime(unixTime.ToString()).Hour);
    Debug.Log(GetTime(unixTime.ToString()).Minute);
    Debug.Log(GetTime(unixTime.ToString()).Second);

单例的一种写法
public class SingleTon:MonoBehaviour where T:MonoBehaviour,new()
{
private static T instance = null;

  private static readonly object locker = new object();

  public static T Instance
  {
      get
     {
         lock (locker)
         {
             if (instance == null)
                 instance = new T();
             return instance;
         }
     }
 }
