/// </summary>

class Program

{

static void Main(string[] args)

{

string source = "Do one thing at a time,and do well";//已知英文语句

string[] stringArray = source.Split(new char[] { ' ', ',' });

var result = stringArray.GroupBy(s => s.Length).Select(s => new {

Lenght = s.Select(x => x).FirstOrDefault().Length,

Count = s.Count(),

StringItems = s.Select(x => x)

});

foreach (var s in result)

{

string strResult = string.Empty;

foreach (var item in s.StringItems)

{

}

Console.WriteLine(string.Format("长度为{0}的单词有{1}个：{2}", s.Lenght, s.Count, strResult));
