xml-個人理財系統(tǒng)

1、一.實驗目的：通過實驗，進一步理解DO項型，熟悉各個語言的xml編程方法。鍛煉軟件開發(fā)能力。二.實驗內(nèi)容：1 、 要求做一個管理信息系統(tǒng)，實現(xiàn)對某個事物的管理，做成網(wǎng)頁的形式(B/S)或者(C/S)形式。要求有界面。2 、 這個系統(tǒng)后臺的數(shù)據(jù)存放在xml 里，要實現(xiàn)對xml 文檔的增刪改查。3 、界面盡可能好看，功能盡可能貼近實際應用。4 、編程語言不限。三實驗步驟或程序(經(jīng)調(diào)試后正確的源程序)1 .登陸界面：namespace XMLpublic partial class Login : Formpublic Login()InitializeComponent();private voi
