Visual C#是微軟公司推出的新一代程序開(kāi)發(fā)語(yǔ)言,是微軟.Net框架中的一個(gè)重要組成部分。屏幕保護(hù)程序是以scr為擴(kuò)展名的標(biāo)準(zhǔn)Windows可執(zhí)行程序。屏幕保護(hù)程序不僅可以延長(zhǎng)顯示器的使用壽命,還可以保護(hù)私人信息。本文向大家介紹一個(gè).Net平臺(tái)上用C#編寫(xiě)的一個(gè)動(dòng)態(tài)文本及圖形的屏幕保護(hù)程序。

   一、具體實(shí)現(xiàn)步驟:

   (1)在Visual Studio.Net下新建一個(gè)C#的Windows應(yīng)用程序工程,不妨命名為screen_saver。

   (2)現(xiàn)在我們來(lái)設(shè)計(jì)程序的主界面:

   先將窗體的Name屬性設(shè)置為screen、Text屬性設(shè)置為空,BackColor屬性設(shè)置為Black、Size屬性設(shè)置為(800, 600)、 ControlBox、MaximizeBox、MinimizeBox、ShowInTaskbar屬性設(shè)置均為false、FormBorderStyle屬性設(shè)置為None。再往窗體上添加Label控件、PictureBox控件、Timer控件各一個(gè)。將Label控件的Name設(shè)置為word、Text屬性設(shè)置為空;將PictureBox控件的Name設(shè)置為picture1、Image設(shè)置為一個(gè)預(yù)知圖片;將Timer控件的Name設(shè)置為timerSaver、Enabled 屬性設(shè)為true、Interval屬性設(shè)為5。

   (3)現(xiàn)在我們開(kāi)始編寫(xiě)完整程序代碼部分:

   最后運(yùn)行該程序,把screen_saver.exe改為screen_saver.scr,拷入Windows系統(tǒng)目錄中,這樣就可以運(yùn)行該屏幕保護(hù)程序。
