坐标转换

    控件坐标与相应地理坐标转换
    

private void axMap1_MouseMoveEvent(object sender, AxMapObjects2._DMapEvents_MouseMoveEvent e)
{

     MapObjects2.Point p1 = axMap1.ToMapPoint(e.x, e.y);//

     textBox1.Text = p1.X.ToString("0.00000");//得到相应经度
     textBox2.Text = p1.Y.ToString("0.00000");
     float xx=0, yy=0;//根据经纬度得到图层平面坐标
     axMap1.FromMapPoint(p1,ref xx, ref yy);

 }
