C#中将数组中相同的元素提取出来如何实现?答:很简单啊,用集合或者字典都可以。建一个字典,数字作为键,出现次数作为值,遍历数组,假如字典里没有,就加到字典里,字典里有,就把次数加一。int[] nums={1,1,2,3,1,2,1,3,3}; Dictionary<int, int> dic = new Dictionary<int, int>(); for (int i = 0; i < nums.Lengt...
C#数组中,把相同的元素提取出来,放入另一个数组中答:string[] array=new string[]{ "7","4","7","1","4","1","5","2","5"} List<string> strList0=new List<string>();//原始数据 List<string> strList1=new List<string>();//数组一,Array1 List<string> strList2=new List<string>();//数组二,Array2 for(int i=0;i...
