linq使两个集合相连接转换为新的集合

static void Main(string[] args)
{
  List<Man> list = new List<Man>();
  for (int i = 0; i < 10; i++)
  {
    Man d = new Man();
    d.Age = i ;
    d.Name = i.ToString();
    list.Add(d);
  }
  List<Test> name = new List<Test>();
  for (int i = 5; i < 10; i++)
  {
    Test d = new Test();
    d.Name = i.ToString();
    name.Add(d);
  }

  List< Test> tsss = (from li in list
          join nm in name
          on li.Name equals nm.Name
          where li.Age > 5
          select new Test
          {
          Name = li.Name,
          NameAge = nm.Name + li.Age.ToString()
          }).ToList();

          Console.WriteLine();
}
