Using Native code is the best. You will need to use WlanQueryInterface() with wlan_intf_opcode_rssi opcode which will return RSSI value as LONG data type. From there you can convert it to dbm.

DWORD WINAPI WlanQueryInterface(
 __in        HANDLE hClientHandle,
 __in        const GUID *pInterfaceGuid,
 __in        WLAN_INTF_OPCODE OpCode,
 __reserved  PVOID pReserved,
 __out       PDWORD pdwDataSize,
 __out       PVOID *ppData,
 __out_opt   PWLAN_OPCODE_VALUE_TYPE pWlanOpcodeValueType
);

Here using opcode wlan_intf_opcode_rssi you will get RSSI value:

WLAN_INTF_OPCODE  >> wlan_intf_opcode_rssi >> LONG

Here is the C++ sample on how to start with:
