Unity读取配置文件

config.ini存放在Assets目录下，项目打包之后存放在Data目录下exe同目录

// 从配置文件读取
        string configFile = Application.dataPath + "/config.ini";//打包好的“xxx_Data”目录貌似没有读取里面的文件权限
        //所以对于打包的程序，需要把配置文件config.ini放在exe同目录下
#if !UNITY_EDITOR
    configFile = System.Environment.CurrentDirectory + "/config.ini";
#endif
        if (File.Exists(configFile))
        {
            ConfigIni ini = new ConfigIni(configFile);
            //host = ini.ReadIniContent("DeepStreamServer", "host");
            //port = ini.ReadIniContent("DeepStreamServer", "port");
            host = ini.keyVal["host"];
            port = ini.keyVal["port"];
            //MessageBox(IntPtr.Zero, configFile+","+host+","+port, "从配置文件读取DeepStream的IP:Port", 0);
        }
