请问哪位高手有AO+C#关于放大,缩小的代码

<P>请问哪位高手有AO+C#关于放大,缩小,平移的代码</P>
<P>教教在下 !!!</P>
<P>急~~~~~~</P>
<P>谢谢了 </P>

<P>这个看VB代码不一样的嘛。所谓的不同语言，仅仅写法不一样而已。</P>

<P>private void button1_Click(object sender, System.EventArgs e)<BR>   {<BR>    axMapControl1.MousePointer = ESRI.ArcGIS.SystemUI.esriControlsMousePointer.esriPointerIdentify;<BR>    flag=4;<BR>   }             </P>
<P>  private void button2_Click(object sender, System.EventArgs e)<BR>  {  <BR>   axMapControl1.MousePointer = ESRI.ArcGIS.SystemUI.esriControlsMousePointer.esriPointerZoomOut;<BR>   flag=1;<BR>  }</P>
<P>  <BR>  </P>
<P>  private void button3_Click(object sender, System.EventArgs e)<BR>  {<BR>   axMapControl1.MousePointer = ESRI.ArcGIS.SystemUI.esriControlsMousePointer.esriPointerZoomIn;<BR>   flag=2;<BR>  }</P>
<P>  private void button4_Click(object sender, System.EventArgs e)<BR>  {<BR>   axMapControl1.Extent = axMapControl1.FullExtent;<BR>   <BR>  }</P>
<P>  private void button5_Click(object sender, System.EventArgs e)<BR>  {<BR>   axMapControl1.MousePointer = ESRI.ArcGIS.SystemUI.esriControlsMousePointer.esriPointerPan;<BR>   flag=3;<BR>  }</P>
<P><BR>  private void axMapControl1_OnMouseDown(object sender, ESRI.ArcGIS.MapControl.IMapControlEvents2_OnMouseDownEvent e)<BR>  {<BR>   ESRI.ArcGIS.Geometry.IEnvelope ipEnv;<BR>   if (flag==2)<BR>   {<BR>    ipEnv=axMapControl1.TrackRectangle();<BR>    axMapControl1.Extent=ipEnv;<BR>   }<BR>   else if(flag==1)<BR>   {<BR>    ipEnv=axMapControl1.TrackRectangle();<BR>    ipEnv= axMapControl1.Extent;<BR>    ipEnv.Expand(2,2,true);<BR>    axMapControl1.Extent =ipEnv;<BR>   }<BR>   else if (flag==3)<BR>   {<BR>    ipEnv= axMapControl1.Extent;<BR>    axMapControl1.Pan();<BR>   }</P>
<P> 这里有一个,希望可以帮上你~~~~~~~~~</P>

<P>这里的缩小好象是指定倍数的吧?</P>
<P>有没有根据鼠标拉出的矩形框定缩小范围的?</P>
