C#获取串口完整名字、并实时监听串口插拔 DaoNetC#

1，首先利用System.Management里面提供的类(第一次可能需要添加对System.Management的引用，否则找不到类)，获取串口完整名字
2，监听窗口USB插拔事件并更新下拉列表中的串口

/// /// 获取串口完整名字（包括驱动名字） /// 如果找不到类，需要添加System.Management引用，添加引用->程序集->System.Management /// Dictionary coms = new Dictionary(); private void getPortDeviceName() {coms.Clear(); using (ManagementObjectSearcher searcher = new ManagementObjectSearcher ("select * from Win32_PnPEntity where Name like '%(COM%'")) { var hardInfos = searcher.Get(); foreach (var hardInfo in hardInfos) { if (hardInfo.Properties["Name"].Value != null) { string deviceName = hardInfo.Properties["Name"].Value.ToString(); int startIndex = deviceName.IndexOf("("); int endIndex = deviceName.IndexOf(")"); string key = deviceName.Substring(startIndex + 1, deviceName.Length - startIndex - 2); string name = deviceName.Substring(0, startIndex - 1); Console.WriteLine("key:"+key+",name:"+name+",deviceName:"+deviceName); coms.Add(key,name); } }//创建一个用来更新UI的委托 (主线程更新) this.Invoke( new Action(() => { comboBox1.Items.Clear(); foreach (KeyValuePair kvp in coms) { comboBox1.Items.Add(kvp.Key + " " + kvp.Value); //更新下拉列表中的串口 }}) ); }}public const int WM_DEVICE_CHANGE = 0x219; public const int DBT_DEVICEARRIVAL = 0x8000; public const int DBT_DEVICE_REMOVE_COMPLETE = 0x8004; /// /// 检测USB串口的拔插 /// /// protected override void WndProc(ref Message m) { if (m.Msg == WM_DEVICE_CHANGE) // 捕获USB设备的拔出消息WM_DEVICECHANGE { switch (m.WParam.ToInt32()) { case DBT_DEVICE_REMOVE_COMPLETE: // USB拔出 {new Thread( new ThreadStart( new Action(() => { getPortDeviceName(); }) ) ).Start(); } break; case DBT_DEVICEARRIVAL: // USB插入获取对应串口名称 { new Thread( new ThreadStart( new Action(() => { getPortDeviceName(); }) ) ).Start(); } break; } } base.WndProc(ref m); }
