.....10w字廢話自動省略,直接開始正題.
首先從最基本的建立winform開始(本項目用的Vs2017)
新建->項目->選中C#->選擇Windows窗體應用->確定
創建完成後可以點擊工具欄進行拖拽控制項 ,雙擊控制項進入事件的邏輯處理,右擊滑鼠選擇屬性進行配置
各屬性的作用可參考微軟文檔 https://docs.microsoft.com/zh-cn/dotnet/api/system.windows.forms.control.accessiblename?view=netframework-4.8
首先展示一下效果圖
註:
博主在一臺電腦上創建了兩個項目,打開兩個VisualStudio(一個運行服務端,一個運行客戶端),
由於socked埠占用問題,
服務端和客戶端運行起來後,
客戶端IP輸入自己電腦的IP->埠port隨便輸入->點擊連接,提示連接成功。例:IP:192.168.1.129 port:80
服務端IP輸入自己電腦IP->埠port隨便輸入--->點擊開始監聽,提示監聽成功。例:IP:192.168.1.129 port:81
客戶端IP輸入自己電腦IP->埠port輸入服務端埠號->點擊連接,提示連接成功可以開始發送消息:例:IP:192.168.1.129 port:81
(從上到下按順序執行)
以上操作是因為服務端、客戶端在同一臺電腦上,造成埠占用, 如果服務端和客戶端分開的話客戶端可以直接輸入服務端ip和埠連接監聽。
接下來貼代碼:
