Arcgis Engine - 脱离ToolBarControl控件的命令和工具

　　可以手动实现脱离ToolBarControl控件的命令和工具

 1 //打开文件.
 2         private void file_tsmItem_Click(object sender, EventArgs e) {
 3             ESRI.ArcGIS.SystemUI.ICommand mxd = new ESRI.ArcGIS.Controls.ControlsOpenDocCommandClass();
 4             mxd.OnCreate(mapCtrl_main.Object);  //传递的应该是AxMapControl.Object,而不是AxMapControl.
 5             mxd.OnClick();
 6         }
 7 
 8         //添加数据.
 9         private void addData_tsmItem_Click(object sender, EventArgs e) {
10             ESRI.ArcGIS.SystemUI.ICommand addData = new ESRI.ArcGIS.Controls.ControlsAddDataCommand();
11             addData.OnCreate(mapCtrl_main.Object);
12             addData.OnClick();
13         }
14         
15         //地图视图.
16         private void zoomIn_tsmItem_Click(object sender, EventArgs e) {
17             ESRI.ArcGIS.SystemUI.ICommand zoomIn = new ESRI.ArcGIS.Controls.ControlsMapZoomInTool();
18             zoomIn.OnCreate(mapCtrl_main.Object);
19             mapCtrl_main.CurrentTool = (ESRI.ArcGIS.SystemUI.ITool)zoomIn;
20         }
21 
22         private void zoomOut_tsmItem_Click(object sender, EventArgs e) {
23             ESRI.ArcGIS.SystemUI.ICommand zoomOut = new ESRI.ArcGIS.Controls.ControlsMapZoomOutTool();
24             zoomOut.OnCreate(mapCtrl_main.Object);
25             mapCtrl_main.CurrentTool = (ESRI.ArcGIS.SystemUI.ITool)zoomOut;
26         }
