基于C#編寫一個(gè)遠(yuǎn)程桌面應(yīng)用

更新時(shí)間：2023年10月24日 08:27:28 作者：每日出拳老爺子

封閉環(huán)境無法拷貝外來的遠(yuǎn)程桌面軟件,所以這篇文章小編就來帶大家用C#編寫一個(gè)簡(jiǎn)單的遠(yuǎn)程桌面應(yīng)用,感興趣的小伙伴可以跟隨小編一起學(xué)習(xí)一下

背景

封閉環(huán)境無法拷貝外來的遠(yuǎn)程桌面軟件，所以就直接自己用C#寫一個(gè)。

效果

說明

本篇會(huì)給出完整的編程步驟，照著寫就能擁有你自己的遠(yuǎn)程桌面應(yīng)用，直接可以運(yùn)行在局域網(wǎng)。

如果不想自己敲代碼，也可以選擇直接下載項(xiàng)目資源，解包后直接用VS2019打開即可運(yùn)行或自行打包成exe

設(shè)計(jì)

遠(yuǎn)程桌面需要一個(gè)服務(wù)端，一個(gè)客戶端，各自是一個(gè)項(xiàng)目文件。
本項(xiàng)目中客戶端分享畫面（發(fā)送截屏數(shù)據(jù)流），服務(wù)端則是監(jiān)聽并接收畫面，因此服務(wù)端需要兩個(gè)Form（窗體）。

項(xiàng)目源碼

客戶端UI

只需要一個(gè)Form1，布局如下：

具體組件和屬性設(shè)置如下：

Label1，text改為IP即可；
Label2，text改為Port即可；
textbox1，名稱改為txtIP；
textbox2，名稱改為txtPort，text改為80
button1，text改為Connect，名稱改為btnConnect
button2，text改為ShareScreen，名稱改為btnShare

服務(wù)端UI Form1

textBox1，name設(shè)置為txtPort
button1，name設(shè)置為btnListen

            btnListen.Enabled = false;
        }
    }
}

Form2

源項(xiàng)目中追加一個(gè)窗體。

一個(gè)窗體里放一個(gè)imageBox，mode設(shè)置為zoom，dock設(shè)置為?？俊?/p>
