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。
