本文介绍了C#中ListView控件的使用，包括添加项目、设置图像列表和为项目分配图像。详细讨论了ListView的重要属性如Activation、View、Columns等，并列举了常用方法如Items.Add和Items.Clear。同时，还展示了如何响应ItemActivate事件来实现不同功能。通过实例代码展示了如何根据用户选择在ListView中动态加载和显示不同内容。

 //ListView列舉檢視控制項
List重要的三項操作就是
1.加入項目(items) listview1.items.add("編輯")
2.設定一個影像清單(ImageList) listview.largimagelist=imgaelist1
3.為每個項目設定影像清單中的影像編號 listview.item[0].imageindex=0
//Listview的常用屬性
Activation 設定或取得ListView點一下就activate或者兩下就activate
SelectedIndices 設定或取得該項目被選取時所顯示的圖像編號
LargeImageList 設定或取得ListView控制項的“大圖示”表，資料類型為imagelist，設定此項目後將view屬性設為largicon就可以顯示大圖示
Smallimagelist 設定或取得listView控制項的"小圖示"表，資料類型為imagelist,高定此貢目後將view屬性設為smallicon就可以顯示小圖示
ex:listView1.LargeImageList=imagelist1
Items 取得ListView 控制項的項目集合
Items[A].ImageIndex　設定ListView控制項的第A個項目中，該項目所顯示的圖像編號，A為大於[-1]的整數
chcekboxes 設定或取得ListView控制項中每個項目的旁邊是否要顯示選取方塊
checkedItems 用來取得listview控制項中目前選取的項目
columns 用來設定或取得listviwe控制項中的所有欄位行道的集合，需設定此項目後將view屬性設為detil就可以顯示詳細清單看，或將view屬性設為tail該項目的資訊顯示於大圖示旁邊

ListVIew常用方法
Items.Add(s)  加入s,s為字串
items.clear() 移除所有項目

ListView常用事件
itemActivate 項止被actiovate時觸發。此時可透過selecteditems[0].text來取得目前被點選的項目
itemCheck 當listview中項目的核取狀態變更時觸發。
itemSelectionChanged 當listview中項目已選取狀態改變時觸發
