字符串合并的问题.

[智者潜行]

A,wxh,cai,

A,wxh,admin2,admin,ccccccc,
有没办法可以让两条或两条以上的字符串合并,相同的就合成一个
比如合成后A,wxh,cai,admin2,admin,ccccccc,

[我姓区不姓区]

            string str1 = "A,wxh,cai,";
            string str2 = "A,wxh,admin2,admin,ccccccc,";
            List<string> list = new List<string>();
            foreach (string s in str1.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries))
                if (!list.Contains(s))
                    list.Add(s);
            foreach (string s in str2.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries))
                if (!list.Contains(s))
                    list.Add(s);
            string result = string.Join(",", list.ToArray());
            Console.WriteLine(result);

用linq更简单,一句话搞定:

            string str1 = "A,wxh,cai,";
            string str2 = "A,wxh,admin2,admin,ccccccc,";
            string result = string.Join(",", string.Concat(str1, str2).Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries).Distinct().ToArray());
            Console.WriteLine(result);

同上...就是一个去掉重复元素的过程啊
