验证问题

Question

有总数不定的string，例下有总数为5的string
a="a"
b="b"
c="c"
d="d"
e="e"需要验证，当这些string同时拥有"b","c","d"的时候return true，反之return false.
如这个例子结果return true.验证条件也会变，如有时候需要同时拥有"c","d","e", "f"。这样的话这个例子结果return false.请教做这个函数的思路。

Answer 1

意思是一堆不一样的string, 当这些string满足里面有3个string等于"b","c","d"的时候通过
如
"a","b","c","d" 4个string, 条件是"a","b","c"则通过，条件是"x","y","z"则不通过。无顺序要求

Answer 2

把字符串存到数组aa中，x1，x2，x3为你要输入判断的字符（如3L说的a,b,c或x，y，z） 
string[] aa = {"a","b","c","d" };
            int count = 0;
            for (int i = 0; i < aa.Length; i++)
            {
                if (aa[i].Contains("x1"))
                {
                    count++;
                }
                if (aa[i].Contains("x2"))
                {
                    count++;
                }
                if (aa[i].Contains("x3"))
                {
                    count++;
                }
            }
            if (count == 3) return true;//三个都包含等于3
            else return false;

Answer 3

数组，List<T>保存数据遍历判断是否contains
返回数据

Answer 4

            String[] strs = { "a","b","c","d"};
            String[] c = {"a","b","c" };            Boolean flag =  true;            List<String> list = new List<String>(strs);
            foreach (String s in c)
            {
                if (!list.Contains(s))
                {
                    flag = false;
                    break;
                }
            }            if (flag)
                Console.WriteLine("pass");
            else
                Console.WriteLine("failed");
