如果判断多行字符串共同含有什么子字符串(该子字符串须长度最长的)

C# code

abcdefghabcdefgxbcdefe...aaabcdefgh

比如上面的多行字符串,含有共同的子字符串,须长度最长的子字符串是:"bcdef"....C#怎么实行吗?

[解决办法]
先找出最短的字串，然后从这个字串截取length,length-1,...，1长度的子串，直到挑出符合条件的为止

string[] str = new string[]{ "gfdsgaaaa", "fds", "fdsgfsdfds", "fdsagfdserre", "rfvffgfdssss" };var query = str.Where(w => w.Contains("fds"));var result = from w in query where w.Length == query.Max(m => m.Length)             select w;foreach (var s in result)    Console.WriteLine(s);
