Question

我正在尝试将连接的WiFi的WiFi SSID与我想要连接的WiFi进行比较。我正在使用rad studio 10.2.3 c ++。所以我使用以下代码：

 _di_JObject obj = SharedActivityContext()->getApplicationContext()-> 
 getSystemService(TJContext::JavaClass->WIFI_SERVICE);
 _di_JWifiManager wifiMng = TJWifiManager::Wrap(((_di_ILocalObject)obj)-> 
 GetObjectID());

 _di_JWifiInfo wifiInfo = wifiMng->getConnectionInfo();

 String ssid = JStringToString(wifiInfo->getSSID()->toString());

 //ive also tried the below code with no success
 String ssid = wifiInfo->getSSID()->toString();

 if(JStringToString(wifiInfo->getSSID()->equals("\"HomeWifi\"")))
 {
    ShowMessage("Connected to: "+JStringToString(wifiInfo->getSSID()));
 }
 else
 {
    ShowMessage("Not connected to: "+JStringToString(wifiInfo->getSSID()));
 }

我在if语句中遇到错误。错误：无法从'const char [12]'转换为'_di_JString'（又名'DelphiInterface'）

请帮忙......

我的问题的解决方案是

if((JStringToString(wifiInfo->getSSID()->toString())) == "\"" + tmpSSID + "\"")

将wifi SSID与c ++中的字符串进行比较
