C# 中常用LInq操作

static void Main(string[] args)
{
int[] a = { , , , , , ,  };
int[] b = { , , , , , ,  };
int[] c = { , , , , , , , , , , ,  }; 

// 交集
var fuck = a.Intersect(b); 

// 并集
var shit = a.Union(b); 

// a有b没有的
var diff1 = a.Except(b); 

// b有a没有的
var diff2 = b.Except(a); 

var max = a.Max();
var min = a.Min();
var avg = a.Average();
var dis = c.Distinct(); 

Print(fuck);
Print(shit);
Print(diff1);
Print(diff2);
Console.WriteLine(max);
Console.WriteLine(min);
Console.WriteLine(avg);
Print(dis); 

Console.ReadKey();
} 

private static void Print(IEnumerable<int> list)
{
foreach (var item in list)
{
Console.Write(item + " ");
}
Console.WriteLine();
}
