我照著網路上的資料用WMI的MSNdis_80211去做 static void Main(string[] args) { try { ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\WMI","SELECT * FROM MSNdis_80211_BSSIList"); ManagementObjectCollection collcetion = searcher.Get(); ManagementObjectCollection.ManagementObjectEnumerator objEnum = collcetion.GetEnumerator(); objEnum.MoveNext(); if (!objEnum.Equals(null)) { Console.WriteLine("無線網路介面: " + objEnum.Current.Properties["InstanceName"].Value); Console.WriteLine("可用無線網路: " + objEnum.Current.Properties["NumberOfItems"].Value); ManagementBaseObject[] objarr = (ManagementBaseObject[])objEnum.Current.Properties["Ndis80211BSSIList"].Value; foreach (ManagementBaseObject queryObj in objarr) { Console.WriteLine("網路名稱 SSID:" + Encoding.ASCII.GetString((byte[])queryObj.Properties["Ndis80211Ssid"].Value)); } } Console.WriteLine("nothing" ); } catch (ManagementException ex) { Console.WriteLine("Error:" + ex.Message); } Console.Read(); } 結果都是Not supported 請問這WMI是沒用了嗎? 為何都是例外? 我是用2008 Express去做,不知道到底怎麼了請有經驗的鄉民指點一二再請教一下在pc上開發跟window mobile有差異嗎因為我在論壇看到這句 "我知道ppc可以利用opennetCF支援的函式庫找到.但是無法移植到PC (XP sp2)上" 我找到以下資訊 Vista WMI does not support the "ManagementObjectSearcher searcher = new ManagementObjectSearcher (@"root\WMI","select Ndis80211ReceivedSignalStrength from MSNdis_80211_ReceivedSignalStrength where active=true");" code for security reasons. You have to use the native Wireless API. 那我pc win7該用什麼方法去做?? 感謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.37.88.195
