WPF实现手风琴式轮播图切换效果
本文实例为大家分享了WPF实现轮播图切换效果的具体代码，供大家参考，具体内容如下
实现效果如下：
步骤：
1、自定义控件MyImageControl
实现图片的裁切和动画的赋值。
publicpartialclassMyImageControl:UserControl
{
publicstaticreadonlyDependencyPropertyShowImageProperty=DependencyProperty.Register("ShowImage",typeof(BitmapImage),typeof(MyImageControl),newPropertyMetadata(null));
publicBitmapImageShowImage
{
get{return(BitmapImage)GetValue(ShowImageProperty);}
set{SetValue(ShowImageProperty,value);}
}
publicMyImageControl()
{
InitializeComponent();
}
publicStoryboardstoryboard=newStoryboard();
privateconstintFlipCount=5;
BitmapSource[]bitmap=newBitmapSource[FlipCount];
Image[]images=newImage[FlipCount];
publicvoidGetHorizontalFlip()
{
intpartImgWidth=(int)this.ShowImage.PixelWidth;
intpartImgHeight=(int)(this.ShowImage.PixelHeight/FlipCount);
for(inti=0;i
2、自定义轮播控件
实现图片点击轮播和动画的启动。
publicpartialclassMyRollControl:UserControl
{
publicMyRollControl()
{
InitializeComponent();
}
///
///是否开始滚动
///
publicboolisBegin=false;
///
///本轮剩余滚动数
///
publicintrollNum=0;
privateList_ls_images;
///
///滚动图片组
///
publicListls_images
{
set
{
if(rollNum>0)
{
//本轮滚动未结束
}
else
{
//开始新的一轮滚动
_ls_images=value;
rollNum=_ls_images.Count();
}
}
get{return_ls_images;}
}
privateintn_index=0;//滚动索引
///
///启动
///
publicvoidBegin()
{
if(!isBegin)
{
isBegin=true;
this.ResetStory();
this.controlFront.GetHorizontalFlip();
}
}
///
///初始化图片
///
voidResetStory()
{
if(this.ls_images.Count>0)
{
this.controlFront.ShowImage=this.ls_images[this.n_index++%this.ls_images.Count];
this.controlBack.ShowImage=this.ls_images[this.n_index%this.ls_images.Count];
}
}
privatevoidmainGrid_MouseDown(objectsender,MouseButtonEventArgse)
{
if(this.controlFront.storyboard.Children.Count>0)
{
if(this.controlBack.storyboard.Children.Count<=0)
{
Canvas.SetZIndex(this.controlFront,0);
this.controlFront.storyboard.Begin();
this.controlBack.GetHorizontalFlip();
rollNum--;
this.ResetStory();
}
}
elseif(this.controlFront.storyboard.Children.Count<=0)
{
if(this.controlBack.storyboard.Children.Count>0)
{
this.controlBack.storyboard.Begin();
rollNum--;
this.ResetStory();
Canvas.SetZIndex(this.controlFront,-1);
this.controlFront.GetHorizontalFlip();
}
}
}
}
3、主窗体调用后台逻辑
publicpartialclassMainWindow:Window
{
publicMainWindow()
{
InitializeComponent();
Listls_adv_img=newList();
ListlistAdv=GetUserImages(@"C:\Image");
foreach(stringainlistAdv)
{
BitmapImageimg=newBitmapImage(newUri(a));
ls_adv_img.Add(img);
}
this.rollImg.ls_images=ls_adv_img;
this.rollImg.Begin();
}
///
///获取当前用户的图片文件夹中的图片路径列表(不包含子文件夹)
///
privateListGetUserImages(stringpath)
{
Listimages=newList();
DirectoryInfodir=newDirectoryInfo(path);
FileInfo[]files=GetPicFiles(path,"*.jpg,*.png,*.bmp,",SearchOption.TopDirectoryOnly);
if(files!=null)
{
foreach(FileInfofileinfiles)
{
images.Add(file.FullName);
}
}
returnimages;
}
privateFileInfo[]GetPicFiles(stringpicPath,stringsearchPattern,SearchOptionsearchOption)
{
ListltList=newList();
DirectoryInfodir=newDirectoryInfo(picPath);
string[]sPattern=searchPattern.Replace(';',',').Split(',');
for(inti=0;i
