OpenFileDialog addShape = new OpenFileDialog(); addShape.Filter = Add Shape File|*.shp; addShape.Title = Add Shape; /点击确定按钮 if (addShape.ShowDialog() = DialogResult.OK) /构造ShapeWorkspace工厂 IWorkspaceFactory factory = new ShapefileWorkspaceFactory(); /利用工厂建立Workspace IFeatureWorkspace fileSpace = factory.OpenFromFile(addShape.FileName.Replace(addShape.SafeFileName, string.Empty), 0) as IFeatureWorkspace; /打开aworkspace中的一个图层（FeatureClass） IFeatureClass featureClass = fileSpace.OpenFeatureClass(addShape.SafeFileName); /建立一个Layer，并初始化 IFeatureLayer layer = new FeatureLayer(); layer.FeatureClass = featureClass; layer.Name = featureClass.AliasName; /将Layer加载到Mapcontrol中 this.axMapControl1.Map.AddLayer(layer); /刷新mapcontrol this.axMapControl1.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGeography, layer, null); /打开MXD文件 private void 打开aMXDToolStripMenuItem_Click(object sender, EventArgs e) OpenFileDialog openfiledialog = new OpenFileDialog(); openfiledialog.Title = 打开地图文档;/名称 openfiledialog.Filter = map documents(*.mxd)|*.mxd;/过滤 openfiledialog.ShowDialog();/显示对话框 string filepath = openfiledialog.FileName; if (axMapControl1.CheckMxFile(filepath) axMapControl1.MousePointer = esriControlsMousePointer.esriPointerArrowHourglass; axMapControl1.LoadMxFile(filepath, 0, Type.Missing); axMapControl1.MousePointer = esriControlsMousePointer.esriPointerDefault;
