C#制作通訊錄

功能說明

<1>四個功能：添加、刪除、修改、查找

<2>添加功能：單擊添加功能，從彈窗中添加數(shù)據(jù)，該功能主要是對文件進(jìn)行操作，因此添加完listview不會顯示新添加的數(shù)據(jù)，關(guān)閉彈窗，單擊主界面更新按鈕，列表就會顯示出剛剛添加的條目（一次添加一條數(shù)據(jù)）

<3>刪除功能，直接對文件進(jìn)行操作實現(xiàn)刪除功能，該功能實時顯示，單擊數(shù)據(jù)項并刪除后，listview內(nèi)和文件內(nèi)數(shù)據(jù)同時刪除

<4>修改功能：選中一行記錄，單擊修改功能， 主窗口跳出修改的組件，在組件內(nèi)修改后單擊更新按鈕，listview內(nèi)數(shù)據(jù)更新，該操作實現(xiàn)的是對listview的操作，關(guān)閉頁面后，提示是否應(yīng)用到通訊錄，單擊是，對應(yīng)TXT文件內(nèi)數(shù)據(jù)會更新，單擊否，則更改不會保存到TXT文件

<5>查找功能：單擊查找按鈕，跳出查找的彈窗，輸入關(guān)鍵字進(jìn)行實時檢索，系統(tǒng)匹配數(shù)據(jù)項，只要包含輸入的關(guān)鍵字的數(shù)據(jù)項都會被檢索出來顯示在列表內(nèi)

缺陷總結(jié)
<1>沒有嚴(yán)格控制輸入格式，如手機號碼尾數(shù)不等于11||6時提示輸入有誤;
<2>子窗口添加數(shù)據(jù)項沒有在父窗口實時顯示，借助了更新按鈕;
<3>查找listview內(nèi)數(shù)據(jù)項和加載txt文件內(nèi)數(shù)據(jù)項到listview內(nèi)基本是遍歷的思想，大型工程不合適
