1.关于本工具
这个工具是我用WPF写的一个测试工具，需求大致上是：有一个文件，它不定期会发生变化，现在要求监控这个文件，每当该文件改变，则创建一个该文件的副本。
在这个程序中，指定一个被监控文件的路径，设定一个拍摄快照的时间间隔，每次拍摄文件的快照后，根据设定比对当次快照与之前快照中文件的大小或最后修改时间，发生变化则创建副本。副本的文件名是当前的时间（时、分、秒、毫秒），副本的扩展名与被监控的文件一致。
程序启动时可以从config.xml中读取配置：
<?xml version="1.0" encoding="gb2312"?> <Config> <FilePath>test.txt</FilePath> <MonInterval>200</MonInterval> <MonType>1</MonType> </Config>
程序的副本被复制到一个名为copy的文件夹中
config.xml与文件夹copy都在工程目录中，在编译后通过后期生成事件命令行复制到可执行文件所在目录下
xcopy "$(ProjectDir)config\config.xml" "$(TargetDir)" /Y xcopy "$(ProjectDir)copy\test.txt" "$(TargetDir)"\copy\ /Y
2.程序界面
界面布局的xaml文档为：
<Window x:Name="wndwCyclop" x:Class="Cyclop.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Cyclop" Height="329" Width="472" ResizeMode="CanMinimize" WindowStartupLocation="CenterScreen" Loaded="wndwCyclop_Loaded" Icon="Cyclop.ico"> <Grid Margin="0,0,4,-2"> <!--程序标题--> <Label x:Name="lblTitle" Content="Cyclop 文件比对兼副本创建工具" HorizontalAlignment="Left" Margin="42,21,0,0" VerticalAlignment="Top" FontSize="24" FontFamily="YouYuan" FontWeight="Bold"/> <!--被监控文件路径--> <Label x:Name="lblFilePath" Content="被监控文件路径：" HorizontalAlignment="Left" Margin="31,76,0,0" VerticalAlignment="Top" Width="101"/> <TextBox x:Name="txtFilePath" HorizontalAlignment="Left" Height="23" Margin="146,79,0,0" Text="" VerticalAlignment="Top" Width="194"/> <Button x:Name="btnBrowse" Content="..."
