LINQ操作数组代码（交集,并集,差集,最值,平均,去重复）

static void Main(string[] args)

{

int[] a = { 1, 2, 3, 4, 5, 6, 7 };

int[] b = { 4, 5, 6, 7, 8, 9, 10 };

int[] c = { 1, 2, 3, 3, 4, 1, 2, 4, 6, 1, 6, 5 };

// 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();

}
