寫在前面：
這個東西是我在網上看了些教程以及源代碼，如果您覺得侵權或者有趣都請您與我聯系，這裏也是班門弄斧，第一次開發小程序，難免會有很多BUG，還請海涵以及多多指正！
代碼相關：
主要利用C#進行編寫，思路是監測網卡，CPU以及監測kernel32.dll當中的內存模塊。
本軟件基本功能有：
1. 檢測網速
2. 查看內存以及CPU使用率
基本界面如下圖所示：
它們的含義：
蠻好用的，日常使用，不怎麽占用空間，第一次做這種東西，還請多多指教！
下面是MainForm

下面是NetMonitorCore
1 using System.Diagnostics; 2 3 namespace NetMonitor 4 { 5 static class NetMonitorCore 6 { 7 private static PerformanceCounterCategory performanceCounterCategory = new PerformanceCounterCategory("Network Interface"); 8 private static string instance = performanceCounterCategory.GetInstanceNames()[1]; 9 private static int interfaceLength = instance.Length; 10 private static PerformanceCounter performanceCounterRecv = new PerformanceCounter("Network Interface", "Bytes Received/sec", instance); 11 private static PerformanceCounter performanceCounterSend = new PerformanceCounter("Network Interface", "Bytes Sent/sec", instance); 12 13 public static float GetNetRecv() 14 { 15 return performanceCounterRecv.NextValue(); 16 } 17 18 public static float GetNetSend() 19 { 20 return performanceCounterSend.NextValue(); 21 } 22 } 23 }
上面就是主要代碼。
