Engine加载ArcGIS Online和ArcGIS Server发布的地图服务

两种方式：
1. 可以通过遍历的方式，根据地图服务的名称进行判断，然后加载。

IAGSServerObjectName pSOName = null;
IAGSServerObjectName psoname = null;
IAGSServerConnection con = new AGSServerConnection();
IAGSServerConnectionFactory2 confactory = new AGSServerConnectionFactory() as IAGSServerConnectionFactory2;
IPropertySet propertyset = new PropertySet();
IMapServerLayer mapserverlayer = new MapServerLayerClass(); 

propertyset.SetProperty(URL, http://192.168.220.116:6080/arcgis/rest/services); 

con = confactory.Open(propertyset, 0); 

IAGSEnumServerObjectName enumSOName = con.ServerObjectNames; 

pSOName = enumSOName.Next();
while (pSOName != null)
{
if (pSOName.Name == MyMapService1)
{
psoname = pSOName;
break;
}
pSOName = enumSOName.Next();
}
IName pName = psoname as IName;
IMapServer mapserver = pName.Open() as IMapServer; 

mapserverlayer.ServerConnect(pSOName, mapserver.DefaultMapName);
axMapControl1.AddLayer(mapserverlayer as ILayer);
axMapControl1.Refresh();

2. Engine 10.1及之后版本的话可以使用IMapServerRESTLayer加载，测试代码：

IMapServerRESTLayer mapServerRESTLayer = new MapServerRESTLayerClass();
            mapServerRESTLayer.Connect(http://cache1.arcgisonline.cn/ArcGIS/rest/services/ChinaOnlineStreetPurplishBlue/MapServer);

            axMapControl1.AddLayer(mapServerRESTLayer as ILayer);
            axMapControl1.Refresh();
