如何在C#Windows 7中从Wlan的空闲状态获取信息 [英] How to get information from the idle state of wlan in C# windows 7

问题描述

In my project I need to detect the idle state of wlan in windows 7, but failed because the class I use System.Net.NetworkInformation Namespace. NET.

该类指定网络接口的操作状态:"休眠，向下，LowerLayerDown，notPresent ，测试，未知，向上"

The class specifies the operational state of the network interface: "Dormant, Down, LowerLayerDown, notPresent, Testing, Unknown, Up"

这些状态似乎都不与wlan的空闲状态相对应.

None of these states seem to correspond to the idle state of wlan.

研究了能量状态如何信息却只发现了. Net紧凑框架位于:枚举_CEDEVICE_POWER_STATE.链接:" msdn.microsoft.com/pt-br/library/aa932261.aspx

Researched how information of energy states but only found the. Net compact framework in: enum _CEDEVICE_POWER_STATE. Link: "msdn.microsoft.com/pt-br/library/aa932261.aspx

我试图对"Win32_NetworkAdapter"进行WMI查询；链接:"http://msdn.microsoft.com/en-us/library/windows/desktop/aa394216(v=vs.85).aspx"字段"uint16可用性"；对于平均值＝ 14 ＝省电-低功率模式"，则为"0". 或值含义＝ 15 ＝省电-待机".但查询仅返回"value = 3 =含义运行或满功率".

I tried to do a WMI query on "Win32_NetworkAdapter" link: "http://msdn.microsoft.com/en-us/library/windows/desktop/aa394216(v=vs.85).aspx" field "uint16 Availability" for "Meaning Value = 14 = Power Save - Low Power Mode" or "Value Meaning = 15 = Power Save - Standby" but the query only returns "value = 3 = Meaning Running or Full Power" even the network adapter off.
