Asp.net(C#)-数组A与数组B的交集

        功能：Asp.net(C#) 用 Linq 实现 数组A与数组B的交集

        用途：比较图片相似程度，以此可以达到程序识别图片

        int[] A = new int[] { 1, 2, 4, 6, 7, 8, 9 };
        int[] B = new int[] { 1, 2, 3, 4, 5, 8, 9 };
        var q = from a in A join b in B on a equals b select b;
        foreach (var n in q)
        {
            Response.Write(n+",");
        }
