如何调用？

private void button1_Click(object sender, EventArgs e)
        {
            AddShapefileUsingOpenFileDialog(axMapControl1.ActiveView);
        }

注意：参数。(axMapControl1.ActiveView)

Classes that implement ICommand：

自定义用户放大工具：

        private void button2_Click(object sender, EventArgs e)
        {
            ICommand command = new ControlsMapZoomInTool();
            command.OnCreate(axMapControl1.Object);
            axMapControl1.CurrentTool = command as ITool;
            //ICommand p = new ControlsMapZoomInFixedCommandClass();
            //p.OnCreate(axMapControl1.Object);
            //axMapControl1.CurrentTool = p as ITool;
            //ICommand p = new ControlsMapZoomInFixedCommandClass();
            //p.OnCreate(axMapControl1.Object);
            //axMapControl1.CurrentTool = p as ITool;
        }

 

自定义用户缩小大工具：

 private void button3_Click(object sender, EventArgs e)
        {
            ICommand pCmd = new ControlsMapZoomOutToolClass();
            pCmd.OnCreate(axMapControl1.Object);
            axMapControl1.CurrentTool = pCmd as ITool;
        }
