WlanGetNetworkBssList與C＃在Windows 10

即時通訊嘗試從Windows 10下的C＃桌面應用程序互操作WlanGetNetworkBssList。有一些問題來正確檢索WLAN_BSS_LIST。不知道問題出在哪裏，我得到的名單是錯誤的。第一項似乎是正確的，但其他所有的都是正確的。我希望有一個人可以幫助我。WlanGetNetworkBssList與C＃在Windows 10

這些是我正在使用的結構。我相信問題是一個錯誤的結構定義。

爲什麼將'dot11BssPhyType'字段（'WLAN_BSS_ENTRY'）的類型設置爲數組？另外，當計算第i個BSS條目的地址時，你可以在指針上使用'ToInt32（）'（我認爲），所以如果你的應用程序是64位的，你可能會丟失一些（32）位。 –
