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。

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,gif
public 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xml
XmlWriter 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();
}
}
}
