WebServices调用AO的方法

1 服务器端代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using ESRI.ArcGIS.esriSystem;
using ESRI.ArcGIS.DataSourcesGDB;
using ESRI.ArcGIS.Geodatabase;
using ESRI.ArcGIS.Geometry;
using ESRI.ArcGIS.DataSourcesFile;

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。
// [System.Web.Script.Services.ScriptService]
public class Service : System.Web.Services.WebService
{
    public Service () {

        //如果使用设计的组件，请取消注释以下行 
        //InitializeComponent(); 
    }

    [WebMethod]
    public string HelloWorld() 
    {
        return "Hello World";
    }
    [WebMethod]
    public bool AddPointToFileGDB(double x, double y)
    {
        IAoInitialize aoInit = new AoInitializeClass();
        aoInit.Initialize(esriLicenseProductCode.esriLicenseProductCodeArcServer);


        IWorkspaceFactory pWSF = new ESRI.ArcGIS.DataSourcesGDB.FileGDBWorkspaceFactoryClass() as IWorkspaceFactory;
        ESRI.ArcGIS.esriSystem.IPropertySet pPropertySet = new ESRI.ArcGIS.esriSystem.PropertySetClass();
        pPropertySet.SetProperty("DATABASE", @"D:\数据\New File Geodatabase.gdb");
        IFeatureWorkspace pFW = pWSF.Open(pPropertySet, 0) as IFeatureWorkspace;
       
        IPoint pPoint = new PointClass();
        pPoint.X = x;
        pPoint.Y = y;

        IFeatureClass pFC = pFW.OpenFeatureClass("point");
      
        IFeature pF = pFC.CreateFeature();
        pF.Shape = pPoint;
        pF.Store();

        return true;
   }
}

2 客户端代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        addpointserver.Service se = new addpointserver.Service();
        se.AddPointToFileGDBCompleted += new addpointserver.AddPointToFileGDBCompletedEventHandler(se_AddPointToFileGDBCompleted);
        se.AddPointToFileGDBAsync(double.Parse(TextBox1.Text),double.Parse( TextBox2.Text));
       
        
    }

    void se_AddPointToFileGDBCompleted(object sender, addpointserver.AddPointToFileGDBCompletedEventArgs e)
    {
        Response.Write("done!");
    }
}

3 注意事项：file gdb所在所在目录必须有 ASPNET角色和NETWorkService角色的读写权限，不然不能读写

4 怎么才能在WinXP下，使得文件夹属性页有“安全”标签页呢？解决方法如下：

1、 打开资源管理器

2、 进入 工具——文件夹选项 菜单，切换到“查看”标签页

3、 去掉“使用简单文件共享（推荐）”选项
