ping的呼叫方法如下:
ping mping=new ping();
mping.pinging(「127.0.0.1「,255,65535);
mping.receive(); //成功接收返回true,timeout 返回false

c 實現ping功能
思路 首先新增一個文字框，用來接收ip地址。用ipaddress myip ipaddress.parse textbox1.text.tostring 把文字框內容變成ip地址，寫到一個異常中，就可以省略掉判斷ip地址是否正確了。定義一個ping的方法 system.net.networkinfo...

linux下實現的ping程式
一 設計目的 ping程式是我們使用的比較多的用於測試網路連通性的程式。ping程式基於icmp，使用icmp的回送請求和回送應答來工作。由計算機網路課程知道，icmp是基於ip的一個協議，icmp包通過ip的封裝之後傳遞。課程設計中選取ping程式的設計，其目的是通過ping程式的設計，能初步掌握...
