ArcGIS 开发的一个问题~SDE连接成功，图层却无法显示

too1998 2011-04-12 05:48:25

SDE连接成功，得到workspace,编译后在GUI上却是白板一个，图层却无法显示，但是提示有坐标的，调试不出来，大家帮我看看是什么原因。

原代码如下：



        private void Form1_Load(object sender, EventArgs e)

        {

            OpenSDEWorkspace("xt-fumeizhi-01", "5151/tcp", "xt", "sa", "123", "sde.DEFAULT");



            #region 



            //绑定要素到控件

            m_mapControl = (IMapControl3)this.axMapControl1.Object;

            m_pageLayoutControl = (IPageLayoutControl2)this.axPageLayoutControl1.Object;







            //初始化controls synchronization calss

            m_controlsSynchronizer = new

            ControlsSynchronizer(m_mapControl, m_pageLayoutControl);

                

            //把MapControl和PageLayoutControl绑定起来(两个都指向同一个Map),然后设置MapControl为活动的Control

            m_controlsSynchronizer.BindControls(true);



            //为了在切换MapControl和PageLayoutControl视图同步，要添加Framework Control

            m_controlsSynchronizer.AddFrameworkControl(axToolbarControl1.Object);

            m_controlsSynchronizer.AddFrameworkControl(this.axTOCControl1.Object);



            // 添加打开命令按钮到工具条

            OpenNewMapDocument openMapDoc = new OpenNewMapDocument(m_controlsSynchronizer);

            axToolbarControl1.AddItem(openMapDoc, -1, 0, false, -1, esriCommandStyles.esriCommandStyleIconOnly);

#endregion

        }

        public IWorkspace OpenSDEWorkspace(string Server, string Instance, string Database, string User, string Password, string version)

        {



            IPropertySet pPropSet = new PropertySetClass();

            IFeatureDataset pFeatureDataset;



            //设置SDE连接属性信息

            IWorkspaceFactory pSdeFact = new SdeWorkspaceFactoryClass();

            pPropSet.SetProperty("SERVER", Server);

            pPropSet.SetProperty("INSTANCE", Instance);

            pPropSet.SetProperty("DATABASE", Database);

            pPropSet.SetProperty("USER", User);

            pPropSet.SetProperty("PASSWORD", Password);

            pPropSet.SetProperty("VERSION", version);

            try

            {

                //打开一个工作空间

                pWorkspace = pSdeFact.Open(pPropSet, 0);

                if (pWorkspace is IFeatureWorkspace)

                {

                    pFeatureWorkspace = pWorkspace as IFeatureWorkspace;

                }

               



                //pFeatureWorkspace = pSdeFact.Open(pPropSet, 0) as IFeatureWorkspace;

                //pFeatureDataset = pFeatureWorkspace.OpenFeatureDataset("cities.sdc");

                pFeatureClass = pFeatureWorkspace.OpenFeatureClass("BOU1_4M_L");

                pFeatureLayer = new FeatureLayerClass();

                pFeatureLayer.FeatureClass = pFeatureClass;

                pFeatureLayer.Name = pFeatureClass.AliasName;



                //this.RenderLayer(pFeatureLayer);

                //pMap = axMapControl1.Map;

                axMapControl1.AddLayer(pFeatureLayer);

                //pMap.AddLayer(pFeatureLayer);

                axMapControl1.Refresh();



               

            }

            catch (Exception ex)

            {

                MessageBox.Show("SDE Cann't Connection");

            }

            return pWorkspace;



        }
