这次活动主要为了吸引广大学生或者.net爱好者的兴趣而编写的一个图片浏览器，实现了“上一张”、“下一张”、“最后一张”、“第一张”的定位功能，并且使用了两种方式（利用PictureBox控件和绘制）来显示图片，还演示了如何将编译后的程序制作成安装包。

 

部分关键代码：

                // 初始化图片装载路径 
                private void InitPath() 
                ...{ 
                        path=System.Environment.GetFolderPath(System.Environment.SpecialFolder.MyPictures); 
                } 
/**//// <summary> 
                /// 根据指定好的路径装载图片 
                /// </summary> 
                /// <returns>返回包含符合条件的图片名称的ArrayList集合</returns> 
                public ArrayList LoadPicture() 
                ...{ 
                        if(path==null) 
                        ...{ 
                                InitPath(); 
                        } 
 
                        ArrayList pictureList=new ArrayList(); 
                        System.IO.DirectoryInfo directoryInfo=new DirectoryInfo(path); 
设置显示的图片类型为jpg、bmp、gif三种#region 设置显示的图片类型为jpg、bmp、gif三种 
                        FileInfo[] jpgFiles=directoryInfo.GetFiles("*.jpg"); 
                        FileInfo[] bmpFiles=directoryInfo.GetFiles("*.bmp"); 
                        FileInfo[] gifFiles=directoryInfo.GetFiles("*.gif"); 
                        #endregion 
 
                        FileInfo[] pictureFiles=new FileInfo[jpgFiles.Length+bmpFiles.Length+gifFiles.Length]; 
                        Array.Copy(jpgFiles,pictureFiles,jpgFiles.Length); 
                        Array.Copy(bmpFiles,0,pictureFiles,jpgFiles.Length,bmpFiles.Length); 
                        Array.Copy(gifFiles,0,pictureFiles,jpgFiles.Length+bmpFiles.Length,gifFiles.Length); 
 
                        for (int i = 0; i < pictureFiles.Length; i++) 
                        ...{ 
                                pictureList.Add(pictureFiles[i].FullName); 
                        } 
                        return pictureList; 
                }
