工作细微基础点

1 Hashtable table = new Hashtable();
2          table.Add("dsa", "das");
3          Console.WriteLine(table);//System.Collections.Hashtable//输出的是类型
4          Console.WriteLine(table.Keys);//System.Collections.Hashtable+KeyCollection
5          Console.WriteLine(table.Values); //System.Collections.Hashtable+ValueCollection
6          Console.WriteLine(table.Keys.Count);  //1
7          Console.ReadKey();
