代码说明：

C#演示 GroupBy字符串操作范例，C# GroupBy将字符串数组按元素长度分组： 　　string[] Words = new string[] { "what", "is", "your", "name", "?", "my", "name", "is", "lyf", "." }; 　　var Groups = from word in Words 　　group word by word.Length into lengthGroups//按单词长度将单词分组 　　orderby lengthGroups.Key descending//按单词长度降序排列 　　select new 　　{ 　　 Length = lengthGroups.Key,//取单词长度 　　 WordCollect = lengthGroups//取该长度的单词分组集合 　　};最后使用foreach循环遍历每组单词，将罗列出包括指定字符的单词是哪几个。
