[英]WlanGetNetworkBssList with c# on windows 10
我试图在Windows 10下从C#桌面应用程序互操作WlanGetNetworkBssList。在正确检索WLAN_BSS_LIST时遇到一些问题。 不知道问题出在哪里,我得到的清单是错误的。 第一项似乎是正确的,但其他所有项都没有。 我希望有一个人可以帮助我。
这些是即时通讯使用的结构。 我认为问题是结构定义错误。
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)]
struct WLAN_BSS_LIST
{
internal Int32 dwTotalSize;
internal Int32 dwNumberOfItems;
internal WLAN_BSS_ENTRY[] wlanBssEntries;
internal WLAN_BSS_LIST(IntPtr ppWlanBssList)
{
dwTotalSize = (Int32)Marshal.ReadInt32(ppWlanBssList);
dwNumberOfItems = (Int32)Marshal.ReadInt32(ppWlanBssList + 4);
wlanBssEntries = new WLAN_BSS_ENTRY[dwNumberOfItems];
int WLAN_BSS_ENTRY_SIZE = Marshal.SizeOf(typeof(WLAN_BSS_ENTRY));
for (int i = 0; i < dwNumberOfItems; i++)
{
IntPtr pItemList = new IntPtr(ppWlanBssList.ToInt32() + i * Marshal.SizeOf(typeof(WLAN_BSS_ENTRY)) + 8);
wlanBssEntries[i] = (WLAN_BSS_ENTRY)Marshal.PtrToStructure(pItemList, typeof(WLAN_BSS_ENTRY));
}
}
}

快速解决方案是将您的代码更改为使用Ilya Konstantinov的Managed Wifi API库。 它已获得MIT许可。 我有一个使用SafeHandles进行所有资源管理的叉子,但是原始代码是可靠的。
