C#中winform下利用ArcEngine调用ArcGIS Server发布的服务
主要使用了AE中的IAGSServerOject接口及IMapServer接口。
Private void GetServerTest_Click(object sender, EventArgs e)
{
//获得服务对象名称
IAGSServerObjectName pServerObjectName =GetMapServer("http://services.arcgisonline.com/ArcGIS/services", "ESRI_Imagery_World_2D", false);
IName pName = (IName)pServerObjectName;
//访问地图服务
IAGSServerObject pServerObject = (IAGSServerObject)pName.Open();
IMapServer pMapServer = (IMapServer)pServerObject;
ESRI.ArcGIS.Carto.IMapServerLayer pMapServerLayer = new ESRI.ArcGIS.Carto.MapServerLayerClass();
//连接地图服务
pMapServerLayer.ServerConnect(pServerObjectName, pMapServer.DefaultMapName);
//添加数据图层
axMapControl1.AddLayer(pMapServerLayer as ILayer);
axMapControl1.Refresh();
}
public IAGSServerObjectName GetMapServer(string pHostOrUrl, string pServiceName, bool pIsLAN)
{
//设置连接属性
IPropertySet pPropertySet = new PropertySetClass();
if (pIsLAN)
pPropertySet.SetProperty("machine", pHostOrUrl);
else
pPropertySet.SetProperty("url", pHostOrUrl);
//打开连接
IAGSServerConnectionFactory pFactory = new AGSServerConnectionFactory();
//Type factoryType = Type.GetTypeFromProgID(
// "esriGISClient.AGSServerConnectionFactory");
//IAGSServerConnectionFactory agsFactory = (IAGSServerConnectionFactory)
// Activator.CreateInstance(factoryType);
IAGSServerConnection pConnection = pFactory.Open(pPropertySet, 0);
//Get the image server.
IAGSEnumServerObjectNamepServerObjectNames = pConnection.ServerObjectNames;
pServerObjectNames.Reset();
IAGSServerObjectName ServerObjectName = pServerObjectNames.Next();
while (ServerObjectName != null)
{
if ((ServerObjectName.Name.ToLower() == pServiceName.ToLower()) &&
(ServerObjectName.Type == "MapServer") )
{
break;
}
ServerObjectName = pServerObjectNames.Next();
}
//返回对象
return ServerObjectName;
}
