C# soe 连接服务，并获取Featureclass

直接上代码：（GetMapServer是做了一个返回多个服务的一个list封装，主要根据pServiceName判断）

//获取服务
        public List<IAGSServerObjectName> GetMapServer(string pHostOrUrl, string pServiceName, bool pIsLAN)
        {

            List<IAGSServerObjectName> ListServerObjectName = new List<IAGSServerObjectName>();
            string[] pServiceNameArr = pServiceName.Split(';');
            //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.
            IAGSEnumServerObjectName pServerObjectNames = pConnection.ServerObjectNames;
            pServerObjectNames.Reset();
            IAGSServerObjectName ServerObjectName = pServerObjectNames.Next();
            while (ServerObjectName != null)
            {
                if (pServiceNameArr.Contains(ServerObjectName.Name) &&
                    (ServerObjectName.Type == "MapServer"))
                {
                    ListServerObjectName.Add(ServerObjectName); break;
                }
                //if ((ServerObjectName.Name.ToLower() == pServiceName.ToLower()) &&
                //    (ServerObjectName.Type == "MapServer"))
                //{
                //    ListServerObjectName.Add(ServerObjectName);
                //    //break;
                //}
                ServerObjectName = pServerObjectNames.Next();
            }
            Marshal.ReleaseComObject(pFactory);
            //返回对象
            return ListServerObjectName;
        }

调用GetMapServer

string serverurl="http://127.0.0.1:6080/arcgis/rest/services/test/Testxztd/MapServer";

//servername可多个用“;”分开；eg:"test/Testxztd;test/sss"

string servername="test/Testxztd"; 
var ids = [0,1];

List<IAGSServerObjectName> tempServerObjectName = GetMapServer("http://127.0.0.1:6080/arcgis/rest/services", servername, false);

            if (tempServerObjectName.Count > 0)
            {
    　　　　　　　//这里是获取为第一个为例子
                var pServerObjectName = tempServerObjectName[0];


                //query.WhereClause = "1=1";//设置SQL语句
                foreach (var i in ids)
                {

                    IName pName = (IName)pServerObjectName;
                    //访问地图服务
                    IAGSServerObject pServerObject = (IAGSServerObject)pName.Open();
                    IMapServer pMapServer = (IMapServer)pServerObject;

                    int id = Convert.ToInt32(i);
                    IRecordSet set = new RecordSet();
                    try
                    {
                        //查询
                        IQueryFilter qy = new QueryFilter();
                        set = pMapServer.QueryFeatureData(MapName, id, qy);
                        ITable table = set.Table;
                        IFeatureClass fc = table as IFeatureClass;

                        if (found2)
                        {
                            qy.WhereClause = where;
                        }
                        IFeatureCursor cursor = fc.Search(qy, false);
                        IFeature feature = null;
                        ISpatialFilter sf = new SpatialFilterClass();
                        while ((feature = cursor.NextFeature()) != null)
                        {
                            //listFeature.Add(feature);
                            //与本图层进行叠加              
                            sf.Geometry = feature.ShapeCopy as IGeometry;
                            sf.SpatialRel = esriSpatialRelEnum.esriSpatialRelIntersects;
                            int temp = this.m_FeatureClass.FeatureCount(sf);
                            if (temp > 0)
                            {
                                pList.Add(feature);
                            }
                        }
                        Marshal.ReleaseComObject(cursor);
                    }
                    catch
                    {
                        // listFeature = null;//当查询结果为空，即查询运算式出错时
                    }
                }

            }
