复制所有目录时跳过"$RECYCLE.BIN“

Question

我正在尝试将所有文件夹复制到c:问题是它一直试图访问回收站文件夹。我试了很多方法来避免它，但都不起作用。我对系统卷信息也有同样的问题，但我只是跳过了它。我不知道为什么这种方法不适用于$recycle.bin

public void Copy(string sourceDirectory, string targetDirectory)
{
    DirectoryInfo diSource = new DirectoryInfo(sourceDirectory);
    DirectoryInfo diTarget = new DirectoryInfo(targetDirectory);
    string[] entries;
    try
    {
        //Gets list of all files and directories (we need it for progress bar)
        entries = Directory.GetFileSystemEntries(sourceDirectory, "*", SearchOption.AllDirectories);
        //entries = Directory.GetFiles(sourceDirectory, "*.*", SearchOption.AllDirectories)
        //    .Where(d => !d.StartsWith("$RECYCLE.BIN"))
        //    .Where(d => !d.StartsWith("System Volume Information")).ToArray();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
        return;
    }

    Invoke(new Action(() => progressBar1.Maximum = entries.Count()));
    Invoke(new Action(() => progressBar1.Step = 1));
    Invoke(new Action(() => progressBar1.Value = 0)); //Using Invoke to prevent Cross thread exception
    CopyAll(diSource, diTarget, entries);
}

public void CopyAll(DirectoryInfo source, DirectoryInfo target, string[] entries)
{
    //    lblInfo.Text = "Copying " + source;

    Directory.CreateDirectory(target.FullName);

    // Copy each file into the new directory.

    foreach (FileInfo fi in source.GetFiles())
    {
        try
        {
            if (source.ToString() != "D:\\$RECYCLE.BIN" && source.ToString() != "System Volume Information")
            {
                if (!IsWorking)

                {
                    Invoke(new Action(() => lblInfo.Text = "Stopped"));
                    return;
                }

                //Using Invoke to prevent Cross thread exception
                Invoke(new Action(() => this.lblInfo.Text = string.Format("Copied {0}\\{1}", source.FullName, fi.Name)));


                if (File.Exists(Path.Combine(target.FullName, fi.Name)))
                {
                    File.Delete(Path.Combine(target.FullName, fi.Name));
                }
                fi.CopyTo(Path.Combine(target.FullName, fi.Name), true);
                Application.DoEvents();

                Invoke(new Action(() => progressBar1.Value++));
            }
        }
        catch (UnauthorizedAccessException ex)
        {
            // ok, so we are not allowed to dig into that directory. Move on.
        }

    }
    // Copy each subdirectory using recursion.

    foreach (DirectoryInfo diSourceSubDir in source.GetDirectories())
    {
        try
        {
            if (diSourceSubDir.ToString() != "System Volume Information" && diSourceSubDir.ToString() != "$RECYCLE.BIN")
            {
                DirectoryInfo nextTargetSubDir =
                    target.CreateSubdirectory(diSourceSubDir.Name);
                CopyAll(diSourceSubDir, nextTargetSubDir, entries);
                Invoke(new Action(() => progressBar1.Value++));
            }

            else
            {
                Invoke(new Action(() => progressBar1.Value = progressBar1.Value + 2));
            }
        }
        catch (UnauthorizedAccessException ex)
        {
            // ok, so we are not allowed to dig into that directory. Move on.
        }
    }

我尝试了注释掉的LINQ和if语句以及大多数在线答案。我不想以管理员身份运行它，我删除了app.manifest文件，感谢您的帮助。

下面是我所做的:我添加了条件并删除了返回；并显示了box，这样当它捕捉到一些东西时，它就会移动到下一个目录。

try
{
    if (!diSource.ToString().Contains("System Volume Information") && 
      !diSource.ToString().ToUpper().Contains("$RECYCLE.BIN"))
    {

        entries = Directory.GetFileSystemEntries(sourceDirectory, "*", 
        SearchOption.AllDirectories);

    }
}

 catch (UnauthorizedAccessException ex)
 {
    //ok, so we are not allowed to dig into that directory. Move on.
 }
