using System.IO;
namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }        private void button1_Click(object sender, EventArgs e)
        {
            
            string sourcepath = AppDomain.CurrentDomain.BaseDirectory+@"\sourcedir";
            string targetpath = AppDomain.CurrentDomain.BaseDirectory+@"\targetdir";
            string filename = string.Empty;
            DirectoryInfo dir = new DirectoryInfo(sourcepath);
            FileInfo[] files = dir.GetFiles();
            foreach(FileInfo fi in files){
                filename = fi.Name;
                fi.CopyTo(targetpath+@"\"+filename,true);
            }
        }
    }
}

有装msdn的话就看看这个ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.NETDEVFX.v20.chs/cpref8/html/M_System_IO_Directory_Move_1_d460c748.htm

Answer 3

public void CopyDir(string sourcedir, string destdir)
        {
            DirectoryInfo source = new DirectoryInfo(sourcedir);
            if (!Directory.Exists(destdir))
                Directory.CreateDirectory(destdir);            FileInfo[] files = source.GetFiles();
            foreach (FileInfo file in files)
            {
                File.Copy(file.FullName, destdir + "\\" + file.Name);
            }
            DirectoryInfo[] dir = source.GetDirectories();
            foreach (DirectoryInfo d in dir)
            {
                Directory.CreateDirectory(destdir + "\\" + d.Name);
                CopyDir(d.FullName, destdir + "\\" + d.Name);
            }        }
 CopyDir(@"D:\Project\Windows Mobile\Windows Mobile\PdaWebServer", @"d:\copy");自己改改吧。你也可以用Process.Start("copy.bat");执行bat文件来执行

Answer 4

用File.Copy()方法或者FileInfo类对象的CopyTo()方法

Answer 5

//项目中添加Microsoft.VisualBasic引用Microsoft.VisualBasic.FileIO.FileSystem.CopyDirectory(
    @"c:\temp\a", @"c:\temp\a_bak");

/// <summary>
        /// 复制目录
        /// </summary>
        /// <param name="srcPath">源路径</param>
        /// <param name="destPath">目标路径</param>
        private void CopyDirectory(string srcPath, string destPath)
        {
            if (!Directory.Exists(srcPath))
            {
                throw new Exception("未找到源路径!");
            }
            if (!Directory.Exists(destPath))
            {
                Directory.CreateDirectory(destPath);
            }
            srcPath = srcPath.Trim();

                }
                File.Copy(fileName, destFileName, true);
            }
            foreach (string directoryName in Directory.GetDirectories(srcPath))
            {
                CopyDirectory(directoryName, destPath);
            }
        }

Answer 7

杂个好象都不行喃。。
我想把@"C:\TEMP\downfile\ 里的文件全部放到@"C:\TEMP\ 后，删除@"C:\TEMP\downfile\里的文件麻烦了

Answer 8

小修改一下代码即可完成楼主问题。
递归？代码只是提供一个思路，并不是终极解决方案。using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO;
namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }        private void button1_Click(object sender, EventArgs e)
        {
            
            string sourcepath = @"c:\\Temp\\downfile";
            string targetpath = @"c:\\Temp";
            string filename = string.Empty;
            DirectoryInfo dir = new DirectoryInfo(sourcepath);
            FileInfo[] files = dir.GetFiles();
            foreach(FileInfo fi in files){
                filename = fi.Name;
                fi.MoveTo(targetpath+@"\"+filename);
            }
        }
    }最后建议楼主学习下C#的io类库。

Answer 9

 递归遍历  
 new DirectoryInfo（） 
 File.Copy

Answer 10

谢谢大家，问题解决了
            // 得到源目录的文件列表，该里面是包含文件以及目录路径的一个数组
                  string[] fileList = Directory.GetFiles(@"C:\TEMP\downfile\");
                   
                    // 遍历所有的文件和目录
                    foreach (string file in fileList)
                    {
                        // 先当作目录处理如果存在这个目录就递归Copy该目录下面的文件
                        if (File.Exists(file))
                        {
                            char c = @"\".ToCharArray(0, 1)[0]; ;
                            string [] fileName=file.Split(c);
                            string destPath = Application.StartupPath+@"\" + fileName[fileName.Length - 1];                             File.Copy(file,destPath, true);
                        }
                        
                     }
