ArcEngine 加載地圖服務數據

加載MapServer

1. 可以通過遍歷的方式，根據地圖服務的名稱進行判斷，然後加載

   namespace DXApplication1
   {
       public partial class Form1 : DevExpress.XtraBars.Ribbon.RibbonForm
       {
           public Form1()
           {
               InitializeComponent();
               axTOCControl1.SetBuddyControl(axMapControl1.Object);
           }

           private void barButtonItem1_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
           {
               LoadMapServer("http://localhost:6080/arcgis/admin", "SampleWorldCities", false);
           }

           private void LoadMapServer(string hostOrUrl, string serviceName, bool isLAN)
           {
               IPropertySet pPropertySet = new PropertySet();
               if (isLAN)
               {
                   pPropertySet.SetProperty("machine", hostOrUrl);
               }
               else
               {
                   pPropertySet.SetProperty("url", hostOrUrl);
               }
   
               // 連接服務器
               IAGSServerConnectionFactory pAGSServerConnectionFactory = new AGSServerConnectionFactory();
               IAGSServerConnection pAGSServerConnection = pAGSServerConnectionFactory.Open(pPropertySet, 0);
   
               // 獲取服務
               IAGSEnumServerObjectName pAGSEnumServerObjectName = pAGSServerConnection.ServerObjectNames;
               pAGSEnumServerObjectName.Reset();
               IAGSServerObjectName pAGSServerObjectName = pAGSEnumServerObjectName.Next();
               while (pAGSServerObjectName != null)
               {
                   if (pAGSServerObjectName.Name.ToLower() == serviceName.ToLower() && pAGSServerObjectName.Type == "MapServer")
                   {
                       break;
                   }
                   pAGSServerObjectName = pAGSEnumServerObjectName.Next();
               }
   
               // 獲取服務圖層
               IAGSServerObject pAGSServerObject = (pAGSServerObjectName as IName).Open() as IAGSServerObject;
               IMapServer pMapServer = pAGSServerObject as IMapServer;
               IMapServerLayer pMapServerLayer = new MapServerLayer() as IMapServerLayer;
               pMapServerLayer.ServerConnect(pAGSServerObjectName, pMapServer.DefaultMapName);
   
               // 添加數據圖層
               axMapControl1.AddLayer(pMapServerLayer as ILayer);
               axMapControl1.Refresh();
           }
       }
   }
   

2. Engine 10.1及之後版本的話可以使用IMapServerRESTLayer加載

   IMapServerRESTLayer mapServerRESTLayer = new MapServerRESTLayerClass();
   mapServerRESTLayer.Connect(http://localhost:6080/arcgis/rest/services/XXXX/MapServer);
   
   axMapControl1.AddLayer(mapServerRESTLayer as ILayer);
   axMapControl1.Refresh();
   

加載帶Token的地圖服務

	gisServer = connectionFactory.Open(connectionProps, 0);

	} 
	return serviceLayer; 
} 

public IMapServer GetMapServer(string agsUrl, string serviceName) 
{ 
	IMapServer mapserver = null;

		IAGSServerObject agsServerObject = (IAGSServerObject)pName.Open(); 
		mapserver = (IMapServer)agsServerObject; 
		break; 
	} 
	agsServerObjectName = agsServerObjectNames.Next(); 
	} 
	
	//Return the image server object. 
	return mapserver; 
} 

public IServerObjectAdmin ConnectAGS(string host, string username, string password) 
{ 
	IServerObjectAdmin m_ServerObjectAdmin = null; 
	try 
	{ 
		IPropertySet propertySet = new PropertySetClass(); 
		propertySet.SetProperty(url, host); 
		propertySet.SetProperty(ConnectionMode, esriAGSConnectionMode.esriAGSConnectionModeAdmin); 
		propertySet.SetProperty(ServerType, esriAGSServerType.esriAGSServerTypeDiscovery); 
		propertySet.SetProperty(user, username); 
		propertySet.SetProperty(password, password); 
		propertySet.SetProperty(ALLOWINSECURETOKENURL, true); 
		IAGSServerConnectionName3 connectName = new AGSServerConnectionNameClass() as IAGSServerConnectionName3; 
		connectName.ConnectionProperties = propertySet; 
		IAGSServerConnectionAdmin agsAdmin = ((IName)connectName).Open() as IAGSServerConnectionAdmin; 
		
		m_ServerObjectAdmin = agsAdmin.ServerObjectAdmin; 
	} 

	catch (Exception exc) 
	{ 
		Console.WriteLine(連接失敗：{0}.Message:{1}, host, exc.Message); 
		return null; 
	} 
	return m_ServerObjectAdmin; 
}

加載本地的切片服務

直接調用IRasterLayer的CreateFromFilePath方法即可
