如何调用本机Wifi功能？

Question

如何在C＃中调用本机Wifi功能，如此

DWORD WINAPI WlanHostedNetworkForceStart(
  _In_        HANDLE hClientHandle,
  _Out_opt_   PWLAN_HOSTED_NETWORK_REASON pFailReason,
  _Reserved_  PVOID pvReserved
);

您需要定义将使用的类型并声明方法。有关详细说明，请参阅Platform Invoke Tutorial。

为了帮助您入门，您需要WLAN_HOSTED_NETWORK_REASON枚举：

public enum WLAN_HOSTED_NETWORK_REASON
{
    wlan_hosted_network_reason_success = 0,
    wlan_hosted_network_reason_unspecified,
    wlan_hosted_network_reason_bad_parameters,
    wlan_hosted_network_reason_service_shutting_down,
    wlan_hosted_network_reason_insufficient_resources,
    wlan_hosted_network_reason_elevation_required,
    wlan_hosted_network_reason_read_only,
    wlan_hosted_network_reason_persistence_failed,
    wlan_hosted_network_reason_crypt_error,
    wlan_hosted_network_reason_impersonation,
    wlan_hosted_network_reason_stop_before_start,
    wlan_hosted_network_reason_interface_available,
    wlan_hosted_network_reason_interface_unavailable,
    wlan_hosted_network_reason_miniport_stopped,
    wlan_hosted_network_reason_miniport_started,
    wlan_hosted_network_reason_incompatible_connection_started,
    wlan_hosted_network_reason_incompatible_connection_stopped,
    wlan_hosted_network_reason_user_action,
    wlan_hosted_network_reason_client_abort,
    wlan_hosted_network_reason_ap_start_failed,
    wlan_hosted_network_reason_peer_arrived,
    wlan_hosted_network_reason_peer_departed,
    wlan_hosted_network_reason_peer_timeout,
    wlan_hosted_network_reason_gp_denied,
    wlan_hosted_network_reason_service_unavailable,
    wlan_hosted_network_reason_device_change,
    wlan_hosted_network_reason_properties_change,
    wlan_hosted_network_reason_virtual_station_blocking_use,
    wlan_hosted_network_reason_service_available_on_virtual_station 
}

接下来，定义本机方法：

[DllImport("Wlanapi.dll", EntryPoint = "WlanHostedNetworkForceStart")]
public static extern uint WlanHostedNetworkForceStart(
    IntPtr hClientHandle, 
    [Out] out WLAN_HOSTED_NETWORK_REASON pFailReason, 
    IntPtr pvReserved);

您只需在C＃代码中的任何位置调用它：

WLAN_HOSTED_NETWORK_REASON failReason;
var result = WlanHostedNetworkForceStart(myClientHandle, out failReason, myReserved);
