    case EngineType.GoogleMaps:
        //设置 GoogleMaps 数据源连接所需要的参数
        datasourceConnectInfo.EngineType = EngineType.GoogleMaps;
        datasourceConnectInfo.Password = "Key";
        datasourceConnectInfo.Alias = "GoogleMap";
        break;

    // SuperMapCloud 数据源
    case EngineType.SuperMapCloud:
        //设置 SuperMapCloud 数据源连接所需要的参数
        datasourceConnectInfo.EngineType = EngineType.SuperMapCloud;
        datasourceConnectInfo.Database = "D:/Cache";
        datasourceConnectInfo.Alias = "SuperMapCloud";
        break;

    // WMTS 服务
    case EngineType.OGC:
        // 设置连接 iServer 所发布的 WMTS 服务所需要的参数
        datasourceConnectInfo.EngineType = EngineType.OGC;
        datasourceConnectInfo.Server = "http://localhost:8090/iserver/services/map-china400/wmts100";
        datasourceConnectInfo.Driver = "WMTS"
        datasourceConnectInfo.Database = "D:/Cache";
        datasourceConnectInfo.Alias = "WMTS";
        break;

datasourceConnectInfo.EngineType根据数据源的引擎类型开打开不同的在线数据
