//string[] names={"Tom","Dick","Harry"};//数组
//IEnumerable<string> filteredName
// = System.Linq.Enumerable.Where(names,n=>n.Length>=4);
////转化为可排序可。。。的IEnumerable<string>类型数据,才能用foreach进行遍历

//foreach (string n in filteredName)
//{ Console.WriteLine(n); }
//Console.ReadKey();
//#endregion
#region 查看var类型的名字
//string[] names ={"Tom","Dick","Harry"};
var names = new string[]{ "Tom", "Dick", "Harry" };
Console.WriteLine("names的数据类型是："+names.GetType().Name);
var car = new SportCar();
Console.WriteLine("car的数据类型是"+car.GetType().Name);
var persons = new List<Person>();//persons的数据类型是List<Person>是列表元素为Person的列表
Console.WriteLine("persons的数据类型是："+persons.GetType().Name);
Console.ReadKey();
#endregion
