Winform窗体效果实例分析

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。
