Hashtable,SoredList,Queue,Stack 的使用

 

 今天我们主要讲了四个应用！这是我所记住的！

《1》；Hashtable

前提是有一个PERSON类是可以用的！

Person 类有两个参数，一个是姓，一个是名！

Hashtable hash = new Hashtable();

        //hash.Add("li", li);

        //hash.Add("zhang", zhang);

        //hash.Add("wang", wang);

 

        //foreach (DictionaryEntry p in hash)

        //{

        //    Person pp = p.Value as Person;

        //    Response.Write(pp.FirstName + pp.LastName + "<br/>");

 

        //}

        //Response.Write("-------------------<br/>");

 

        //foreach (Person p in hash.Values)

        //{

        //    Response.Write(p.FirstName + p.LastName + "<br/>");

 

        //}

《2》SortedList

  Person li = new Person("李¤?", "小?虎¡é");

        Person zhang = new Person("张?", "大䨮龙¢¨²");

        Person wang = new Person("王ª?", "中D飞¤¨¦");

 

        SortedList list = new SortedList();

        list.Add("a",li);

        list.Add("b", zhang);

        list.Add("c", wang);

 

 

 

        int index = list.IndexOfKey("b");

        Response.Write(index + "<br/>");

        index = list.IndexOfValue(zhang);

        Response.Write(index + "<br/>");

 

 

        Person p = (Person)list.GetByIndex(index);

        Response.Write(p.FirstName+p.LastName);

        Person pp = (Person)list["c"];

<3>queue

//Response.Write("<br/>---------------<br/>");

        //Queue qu = new Queue();

        //qu.Enqueue("welcome");

        //qu.Enqueue("to");

        //qu.Enqueue("china");

        ////取¨?出?数ºy据Y，ê?先¨¨进?先¨¨出?，ê?取¨?完ª¨º以°?后¨®！ê?qu里¤?的Ì?数ºy据Y为a空?了¢?就¨ª

        //int nums = qu.Count;

        //for (int i = 0; i < nums; i++)

        //{

        //    Response.Write(qu.Dequeue().ToString()+ " ");

 

 

        //}

<4>statck

   //Response.Write("<br/>---------------<br/>");

        //Stack st = new Stack();

        //st.Push("welcome");

        //st.Push("to");

        //st.Push("china");

        //int num = st.Count;

        //for (int i = 0; i < num; i++)

        //{

        //    Response.Write(st.Pop().ToString() + " ");

 

 

        //}
