2、POP3通信的基本步驟和程序框架30實驗六、GDI+的應(yīng)用68實驗七、基于組件的開發(fā)技術(shù)68實驗八、web service的開發(fā)與應(yīng)用68實驗一、委托與事件 實驗?zāi)康模毫私馕信c事件的基本概念，學(xué)習(xí)使用委托與事件進行簡單的程序開發(fā) 實驗內(nèi)容與步驟：1 聲明一個委托類型和一個事件2編寫調(diào)用事件的方法3編寫事件的處理方法4將事件和委托關(guān)聯(lián)5編寫主程序驗證 參考代碼： using System;namespace MyCollections using System.Collections;public delegate void ChangedEventHandler(object sender,

3、 EventArgs e);public class ListWithChangedEvent: ArrayList public event ChangedEventHandler Changed;protected virtual void OnChanged(EventArgs e) if (Changed != null)Changed(this, e);public override int Add(object value) int i = base.Add(value);OnChanged(EventArgs.Empty);return i;public override voi

4、d Clear() base.Clear();OnChanged(EventArgs.Empty);public override object thisint index set baseindex = value;OnChanged(EventArgs.Empty);namespace TestEvents using MyCollections;class EventListener private ListWithChangedEvent List;public EventListener(ListWithChangedEvent list) List = list;List.Chan

5、ged += new ChangedEventHandler(ListChanged);private void ListChanged(object sender, EventArgs e) Console.WriteLine(開始讓我處理了！);public void Detach() List.Changed -= new ChangedEventHandler(ListChanged);List = null;class Test public static void Main() ListWithChangedEvent list = new ListWithChangedEvent

6、();EventListener listener = new EventListener(list);list.Add(item 1);list.Clear();listener.Detach();Console.Read();實驗二、控件應(yīng)用實驗?zāi)康?熟悉C#.NET的winform窗體控件和WEB控件的使用 實驗要求：1、winform窗體控件使用:設(shè)計一個winform窗體，包括mainmenu控件、textbox控件、tooltip控件、tabcontrol控件、listview控件，并編寫相應(yīng)的事件響應(yīng)代碼2、簡單網(wǎng)頁：設(shè)計一個網(wǎng)頁，包括button控件、textbox控件、pan

7、el控件、listbox控件、dropdownlist控件、image控件、hyperlink控件、table控件、marquee控件、embed控件、iframe控件、彈出對話框、驗證控件，并編寫相應(yīng)的響應(yīng)代碼。實驗三、ADO.NET編程 實驗?zāi)康模簩W(xué)習(xí)數(shù)據(jù)庫聯(lián)接，了解sqldataadapter和sqldatareader工作原理 實驗內(nèi)容與要求： 1、 編程聯(lián)接數(shù)據(jù)庫，在winform上顯示sqlserver2000中的pubs數(shù)據(jù)庫的authers的內(nèi)容，利用水晶報表把顯示的內(nèi)容生成報表；比較sqldataadapter和sqldatareader的區(qū)別。 2、自建用自動增量做主碼的數(shù)

8、據(jù)表，使用dataset和datagrid在網(wǎng)頁中分頁顯示表中的數(shù)據(jù)；然后a) 使用交互方式在dataset中添加十條記錄，并顯示在datagrid中;b) 再刪去3條，并顯示在datagrid中;c) 再增加2條，并顯示在datagrid中;d) 再使用dataset修改數(shù)據(jù)表。實驗四、實現(xiàn)tcp點對點通信、udp點對點、組播的步驟和程序基本架構(gòu)實驗?zāi)康模簩崿F(xiàn)tcp點對點通信、udp點對點、組播的步驟和程序基本架構(gòu)實驗內(nèi)容與要求： 閱讀和調(diào)試完成下列參考程序；修改UDP點對點程序使它能進行在廣域網(wǎng)中兩局域網(wǎng)（10.1.1.*和11.1.1.*）之間進行點對點通信。網(wǎng)絡(luò)拓?fù)鋱D如下，其中ip:1
