ADF连接SOM

   

VS2008新建一个应用如下：

 

 

添加引用如下：

 

 

 

 

service.cs的内容

 

using System;using System.Collections.Generic;using System.Linq;using System.Runtime.Serialization;using System.ServiceModel;using System.Text;using System.Collections;

using ESRI.ArcGIS.Server;using ESRI.ArcGIS.ADF;using ESRI.ArcGIS.ADF.Connection.Local;using ESRI.ArcGIS.ADF.Connection.AGS;using ESRI.ArcGIS.Carto;using ESRI.ArcGIS.Geodatabase;

// 注意: 如果更改此处的类名“Service”，也必须更新 Web.config 和关联的 .svc 文件中对“Service”的引用。public class Service : IService{ public ArrayList GetProvinceNames(string country) { string username = "ArcGISSOM"; string password = "111"; string domain = "ohn-THINK"; string hostname = "localhost"; ArrayList results = new ArrayList(); IServerContext serverContext = null; try { using (ComReleaser comReleaser = new ComReleaser()) { // Create the user identity. ESRI.ArcGIS.ADF.Identity userIdentity = new ESRI.ArcGIS.ADF.Identity(username, password, domain);

AGSServerConnection agsConnnection = new AGSServerConnection(hostname, userIdentity); agsConnnection.Connect(); IServerObjectManager som = agsConnnection.ServerObjectManager; comReleaser.ManageLifetime(som);

serverContext = som.CreateServerContext("World", "MapServer"); IMapServer ms = (IMapServer)serverContext.ServerObject; IMapServerObjects mapObjs = ms as IMapServerObjects; IMap map = mapObjs.get_Map(ms.DefaultMapName); ILayer layer = map.get_Layer(0); // cities 图层 IFeatureLayer flayer = layer as IFeatureLayer; IFeatureClass featClass = flayer.FeatureClass;

IQueryFilter qf = new QueryFilterClass(); qf.WhereClause = "CNTRY_NAME='" + country + "'"; ICursor cursor = (ICursor)featClass.Search(qf, false); IDataStatistics dataStatistics = new DataStatisticsClass(); dataStatistics.Field = "ADMIN_NAME"; dataStatistics.Cursor = cursor; System.Collections.IEnumerator enumerator = dataStatistics.UniqueValues; enumerator.Reset();

while (enumerator.MoveNext()) { string countryname = enumerator.Current.ToString(); results.Add(countryname); } serverContext.ReleaseContext(); } } catch { serverContext.ReleaseContext(); } return results; }

public string GetData(int value) { return string.Format("You entered: {0}", value); }

public CompositeType GetDataUsingDataContract(CompositeType composite) { if (composite.BoolValue) { composite.StringValue += "Suffix"; } return composite; }}

 

 

 

 IService.cs的内容

using System;using System.Collections.Generic;using System.Linq;using System.Runtime.Serialization;using System.ServiceModel;using System.Text;using System.ServiceModel.Web;using System.Collections;// 注意: 如果更改此处的接口名称“IService”，也必须更新 Web.config 中对“IService”的引用。[ServiceContract]public interface IService{ [WebGet] [OperationContract] ArrayList GetProvinceNames(string country);

[OperationContract] string GetData(int value);

[OperationContract] CompositeType GetDataUsingDataContract(CompositeType composite);

// 任务: 在此处添加服务操作}

// 使用下面示例中说明的数据约定将复合类型添加到服务操作。[DataContract]public class CompositeType{ bool boolValue = true; string stringValue = "Hello ";

[DataMember] public bool BoolValue { get { return boolValue; } set { boolValue = value; } }

[DataMember] public string StringValue { get { return stringValue; } set { stringValue = value; } }}

 

web.config

<%@ ServiceHost Language="C#" Debug="true" Service="Service" CodeBehind="~/App_Code/Service.cs" %>
