c#图片自动播放程序

filp_v2系统，是练习c#控件的很好Demo案例。它包含了菜单、多窗口、图片框、复选框、容器等控件。
功能如下：
1：通过定时器完成自动翻转
2：设置毫秒值保存到xml数据中
3：文件夹对话框
4：文件对话框
5：自定义输入文件或目录

6：多个form之间数据共享

由于代码比较多，下面贴出核心代码

|---获取所有可执行文件、初始化xml保存数据。

using System;using System.IO;using System.Collections;using System.Collections.Generic;using System.Xml;namespace flip_v2{/** 图片+Xml工具类*/public class ImgTool{/** * * 传递一个完整路径，返回一个ilst集合，0为路径（不含文件名）1：播放的文件名(不包含路径) * 如C:\Users\Public\Pictures\Sample Pictures\八仙花.jpg * 0:C:\Users\Public\Pictures\Sample Pictures * 1:八仙花.jpg */public static string[] pathToList(string path){string[] array = new string[2];int last = path.LastIndexOf("\\");if(last!=-1){array[0]=(path.Substring(0,last));array[1]=(path.Substring(last+1));}return array;}/**把所有文件封装到map中  key为uint64  value=string*/public static Dictionary<UInt64,string> pathToMap(string path){Dictionary<UInt64,string> dict = new Dictionary<UInt64,string>();DirectoryInfo info = new DirectoryInfo(path);FileSystemInfo[] fileSystem = info.GetFileSystemInfos();UInt64 count = 1;//获取所有子文件(不包含子文件夹),foreach(FileSystemInfo f in fileSystem){FileInfo file = f as FileInfo;if(file!=null && fileterEndName(file.Name))dict.Add(count++,f.FullName);}return dict;}//文件过滤器：png,jpg,gifpublic static bool fileterEndName(string endName){endName = endName.ToLower();bool b = false;string tag = ".png|.jpg|.gif";int last = endName.LastIndexOf(".");if(last!=-1){endName = endName.Substring(last);if(tag.Contains(endName))b= true;}return b;}/**操作xml:默认保存到c:\\property.xml*/public static void createXml(string path){//xml样式 XmlWriterSettings settings = new XmlWriterSettings();settings.Indent = true;settings.NewLineOnAttributes = false;//本地创建一个新的xmlXmlWriter write = XmlWriter.Create(path,settings);write.WriteStartDocument();write.WriteStartElement("property");write.WriteStartElement("time");write.WriteAttributeString("id","setTime");write.WriteValue("3000");write.WriteEndElement();write.WriteStartElement("localhostPath");write.WriteAttributeString("id","setInputBoxPath");write.WriteValue("");write.WriteEndElement();write.WriteEndElement();write.WriteEndDocument();//刷新缓冲区，并释放资源write.Flush();write.Close();}}}
