本文实例分析了winform窗体效果。分享给大家供大家参考。具体如下:

using system;
using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.text;
using system.windows.forms;
namespace windowsapplication4
{
 public partial class form3 : form
 {
  bool flag = false;
  public form3()
  {
   initializecomponent();
   flag = true;
  }
  #region user32.dll
  //导入user32.dll
  [system.runtime.interopservices.dllimport("user32")]
  //声明api函数
  private static extern bool animatewindow(intptr hwnd, int dwtime, int dwflags);
  #endregion
  #region 常量
  //正面_水平方向
  const int aw_hor_positive = 0x0001;
  //负面_水平方向
  const int aw_hor_negative = 0x0002;
  //正面_垂直方向
  const int aw_ver_positive = 0x0004;
  //负面_垂直方向
  const int aw_ver_negative = 0x0008;
  //由中间四周展开或
  const int aw_center = 0x0010;
  //隐藏对象
  const int aw_hide = 0x10000;
  //显示对象
  const int aw_activate = 0x20000;
  //拉幕滑动效果
  const int aw_slide = 0x40000;
  //淡入淡出渐变效果
  const int aw_blend = 0x80000;
  #endregion
  #region 判断方向
  public int ishororver(int pos)
  {
   int rtn = 0;
   //判断是正方向还是反方向
   if (pos.equals(0))
   {
    //判断是横向还是纵向
    if (flag)
     rtn = aw_hor_positive;
    else rtn = aw_ver_positive;
   }
   else if (pos.equals(1))
   {
    //判断是横向还是纵向
    if (flag)
     rtn = aw_hor_negative;
    else rtn = aw_ver_negative;
   }
   return rtn;
  }
  #endregion
  private void button1_click(object sender, eventargs e)
  {
   //动画——窗体向上拖拉
   animatewindow(this.handle, 1000, aw_slide | aw_hide | ishororver(1));
   //动画——窗体向下拖拉
   animatewindow(this.handle, 1000, aw_slide | aw_activate | ishororver(0));
   //动画——窗体淡出特效
   animatewindow(this.handle, 1000, aw_blend | aw_hide | ishororver(1));
   //动画——窗体淡入特效
   animatewindow(this.handle, 1000, aw_blend | aw_activate | ishororver(0));
   //动画——窗体由四周向中心缩小直至消失
   animatewindow(this.handle, 1000, aw_center | aw_hide | ishororver(1));
   //动画——窗体由中心向四周扩展
   animatewindow(this.handle, 1000, aw_center | aw_activate | ishororver(0));
  }
 }
}

希望本文所述对大家的c#程序设计有所帮助。
