c# 求提供思路,我str1“i want to eat an apple” str2"i want eat apple

string[] aa; string[] bb; string str1="i want to eat an apple"; string str2="i want eat apple"; aa = str1.Split(' '); bb = str2.Split(' '); int count=0; foreach(string c in aa) { count = 0; for (int i = 0; i < bb.Length; i++) { if (c != bb[i]) { count++; } if (count == bb.Length) { Console.Write(c+' '); } } } Console.ReadKey(); 已经把to和an两个缺失的单词在控制台输出了。你拿去用吧。
