带进度条的文件夹拷贝

.net没有提供文件夹的拷贝,今天写了一个：

效果如图 

private void ultraButton1_Click(object sender, System.EventArgs e)  {   if(!System.IO.Directory.Exists(txtSourceDirectory.Text))   {    MessageBox.Show("源文件夹不存在","",MessageBoxButtons.OK,MessageBoxIcon.Warning);    txtSourceDirectory.Focus();    return;   }   if(!System.IO.Directory.Exists(txtAimDirectory.Text))   {    MessageBox.Show("目标文件夹不正确","",MessageBoxButtons.OK,MessageBoxIcon.Warning);    txtAimDirectory.Focus();    return ;   }         cdw.OnCopyFile+=new Nexsmart.MMS.FileManager.Class.CopyDirectoryWorker.CopyFileEventHandler(cdw_OnCopyFile);   cdw.WorkOvered+=new Nexsmart.MMS.FileManager.Class.CopyDirectoryWorker.WorkOverEventHandler(cdw_WorkOvered);

   cdw.SourceDirectory=this.txtSourceDirectory.Text;   cdw.AimDirectory=this.txtAimDirectory.Text;      btnControl.Visible=true;   btnControl.Text="暂停拷贝";

   btnAbort.Visible=true;

   this.timer1.Enabled=true;   this.timer1.Start();   thread.Start();//        }

  private void cdw_OnCopyFile(long lngHad, long lngCount, string strShow)  {   this.pbarDirectory.Maximum=(int)lngCount;   this.pbarDirectory.Value=(int)lngHad;

   lblShow.Text=strShow;

   this.lblCount.Text=Convert.ToString(lngCount/1024)+" KB";   this.lblHad.Text=Convert.ToString(lngHad/1024)+" KB";    }

  private void cdw_WorkOvered()  {   this.pbarDirectory.Value=0;   this.pbarDirectory.Visible=false;      this.timer1.Stop();   this.lblShow.Text="";   this.Elapse=0;   MessageBox.Show("复制完成","",MessageBoxButtons.OK,MessageBoxIcon.Information);  }

  private void timer1_Tick(object sender, System.EventArgs e)  {   ++Elapse;   lblTime.Text=Elapse.ToString()+" 秒";  }

实现类

public class CopyDirectoryWorker {  public delegate void CopyFileEventHandler(long lngHad,long lngCount,string strShow);//定义一个委托  public event CopyFileEventHandler OnCopyFile;//定义一个事件,在Copy文件时触发    public delegate void WorkOverEventHandler();//定义一个委托  public event WorkOverEventHandler WorkOvered;//定义一个事件,在Copy文件完成时触发

  public CopyDirectoryWorker()  {   //   // TODO: 在此处添加构造函数逻辑   //  }

  private string _sourceDirectory;  public string SourceDirectory  {   get   {    return _sourceDirectory;   }   set   {    _sourceDirectory=value;   }  }

  private string _aimDirectory;  public string AimDirectory  {   get   {    return _aimDirectory;   }   set   {    _aimDirectory=value;   }  }

  /// <summary>  /// 递归拷贝文件,把源目录下所有文件和文件夹拷贝到目标目录  /// </summary>  /// <param name="sourceDirectory">源路径</param>  /// <param name="aimDirectory">目标路径</param>  public void CopyFiles()  {   if(!System.IO.Directory.Exists(SourceDirectory)&!System.IO.Directory.Exists(AimDirectory))    // return ;    throw new Exception("文件夹不存在");

   string strTemp=SourceDirectory.Substring(SourceDirectory.LastIndexOf(@"/"));      string strRealAimDirecotry=AimDirectory+strTemp;// System.IO.Path.Combine(aimDirectory,strTemp);      if(!System.IO.Directory.Exists(strRealAimDirecotry))    System.IO.Directory.CreateDirectory(strRealAimDirecotry);      RecursionCopyFiles(SourceDirectory,strRealAimDirecotry);//调用真正文件夹复制程序

   WorkOvered();//触发事件，调用完成复制后的处理程序  }

  /// <summary>  /// 二进制读取文件,任何文件  /// </summary>  private void CopyFile(string SourceFile,string AimFile)  {   byte[] bytTemp=new byte[4096];//字节数组

   long lngHad=0;   long lngCount;   int z=5000;      //源文件流   System.IO.FileStream fsSource=new System.IO.FileStream(SourceFile,System.IO.FileMode.Open,System.IO.FileAccess.Read,System.IO.FileShare.Read,4);   //二进制读取器   System.IO.BinaryReader bRead=new System.IO.BinaryReader(fsSource);   //定位源文件流的头部   bRead.BaseStream.Seek(0,System.IO.SeekOrigin.Begin);   if(fsSource.Position>0)    fsSource.Position=0;

   lngCount=fsSource.Length;

   if(System.IO.File.Exists(AimFile))    System.IO.File.Delete(AimFile);

   //目标文件流   System.IO.FileStream fsAim=new System.IO.FileStream(AimFile,System.IO.FileMode.CreateNew,System.IO.FileAccess.Write,System.IO.FileShare.Write,4);   //二进制写入器   System.IO.BinaryWriter bWrite=new System.IO.BinaryWriter(fsAim);

   while(z>=4096)   {    z=(int)bRead.Read(bytTemp,0,bytTemp.Length);//读入字节数组,返回读取的字节数量，如果小于4096，则到了文件尾    bWrite.Write(bytTemp,0,bytTemp.Length);//从字节数组写入目标文件流        lngHad+=z;    string show="从"+SourceFile+"到"+AimFile;    OnCopyFile(lngHad,lngCount,show);//触发事件 来控制主线程 这里是进度条和已完成复制文件字节显示      }

   bWrite.Flush();//清理缓存区

   bWrite.Close();   bRead.Close();

   fsAim.Close();   fsSource.Close();

  }    /// <summary>  /// 递归拷贝文件,把源目录下所有文件和文件夹拷贝到目标目录  /// </summary>  /// <param name="sourceDirectory">源路径</param>  /// <param name="aimDirectory">目标路径</param>  private bool RecursionCopyFiles(string sourceDirectory,string aimDirectory)  {   if(!System.IO.Directory.Exists(sourceDirectory)&!System.IO.Directory.Exists(aimDirectory))//    return false;   try   {    string[] directories=System.IO.Directory.GetDirectories(sourceDirectory);    if(directories.Length>0)    {     foreach(string dir in directories)//递归调用     {      RecursionCopyFiles(dir,aimDirectory+dir.Substring(dir.LastIndexOf(@"/")));//attention: "/" cann't instead of "/"     }    }
