WlanGetNetworkBssList with c# on windows 10
本文关键字:windows on with WlanGetNetworkBssList | 更新日期: 2023-09-27 18:07:25
我试图从Windows 10下的c#桌面应用程序互操作WlanGetNetworkBssList。正确检索WLAN_BSS_LIST有一些问题。不知道问题在哪里,我得到的列表是错误的。第一项似乎是正确的,但其他的都不对。我希望有人能帮助我。
这些是我使用的结构。我认为问题是错误的结构定义。
[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));
}
}
}

快速解决方法是更改代码以使用Ilya Konstantinov的Managed Wifi API库。它是在MIT许可下的。我有一个分支,使用SafeHandles的所有资源管理,但原始代码是坚实的。
