使用WPF做的一个简单的操作文件的demo，包括复制和移动文件夹，核心思想就是使用递归，如果只是移动或者复制单一文件，直接使用File.Copy()或者File.Move()方法即可。
XAML代码
<Window x:Class="OperationFile.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:OperationFile"
mc:Ignorable="d"
Title="MainWindow" Height="220" Width="300">
<Grid>
<Button Content="复制文件" HorizontalAlignment="Left" VerticalAlignment="Top" Height="30" Width="100" Margin="80,20"
x:Name="btnCopy" Click="btnCopy_Click"/>
<Button Content="移动文件" HorizontalAlignment="Left" VerticalAlignment="Top" Height="30" Width="100" Margin="80,70"
x:Name="btnMove" Click="btnMove_Click"/>
</Grid>
</Window>后端代码如下：
using System;
using System.Windows;
namespace OperationFile
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
/// <summary>
/// 移动文件夹（拷贝）
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void btnMove_Click(object sender, RoutedEventArgs e)
{
try
{
FileUtility.MoveFolder(@"C:\Test", @"D:\Raw Data\Temp");
MessageBox.Show("移动文件夹完成");
}
catch (Exception ex)
{
MessageBox.Show("移动文件夹出错");
}
}
/// <summary>
/// 复制文件夹
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void btnCopy_Click(object sender, RoutedEventArgs e)
{
try
{
FileUtility.CopyFolder(@"C:\Test", @"D:\Raw Data\Temp");
MessageBox.Show("复制文件夹完成");
}
catch (Exception ex)
{
MessageBox.Show("复制文件夹出错");
}
}
}
}FileUtility类代码
using System;
using System.IO;
namespace OperationFile
{
public static class FileUtility
{
/// <summary>
/// 复制文件夹及文件
/// </summary>
/// <param name="sourceFolder">原文件路径</param>
/// <param name="destFolder">目标文件路径</param>
/// <returns></returns>
public static void CopyFolder(string sourceFolder, string destFolder)
{
try
{
//如果目标路径不存在,则创建目标路径
if (!Directory.Exists(destFolder))
{
Directory.CreateDirectory(destFolder);
}
//得到原文件根目录下的所有文件
string[] files = Directory.GetFiles(sourceFolder);
foreach (string file in files)
{
string name = Path.GetFileName(file);
string dest = Path.Combine(destFolder, name);
// 复制文件
File.Copy(file, dest);
}
//得到原文件根目录下的所有文件夹
string[] folders = Directory.GetDirectories(sourceFolder);
foreach (string folder in folders)
{
string dirName = folder.Split('\\')[folder.Split('\\').Length - 1];
string destfolder = Path.Combine(destFolder, dirName);
// 递归调用
CopyFolder(folder, destfolder);
}
}
catch (Exception ex)
{
throw new Exception($"copy file Error:{ex.Message}\r\n source:{ex.StackTrace}");
}
}
/// <summary>
/// 移动文件
/// </summary>
/// <param name="sourceFolder">源文件夹</param>
/// <param name="destFolder">目标文件呢</param>
public static void MoveFolder(string sourceFolder, string destFolder)
{
try
{
//如果目标路径不存在,则创建目标路径
if (!Directory.Exists(destFolder))
{
Directory.CreateDirectory(destFolder);
}
//得到原文件根目录下的所有文件
string[] files = Directory.GetFiles(sourceFolder);
foreach (string file in files)
{
string name = Path.GetFileName(file);
string dest = Path.Combine(destFolder, name);
// 移动文件
File.Move(file, dest);
}
//得到原文件根目录下的所有文件夹
string[] folders = Directory.GetDirectories(sourceFolder);
foreach (string folder in folders)
{
string dirName = folder.Split('\\')[folder.Split('\\').Length - 1];
string destfolder = Path.Combine(destFolder, dirName);
// 递归调用
MoveFolder(folder, destfolder);
}
// 删除源文件夹
Directory.Delete(sourceFolder);
}
catch (Exception ex)
{
throw new Exception($"move file Error:{ex.Message}\r\n source:{ex.StackTrace}");
}
}
}
