唯一应该做的就是将可选递归参数设置为True。

Directory.Delete（“C:\MyDummyDirectory”，True）

感谢.NET。：）

要删除文件夹，这是使用文本框的代码和使用System.IO；的按钮：

private void Deletebt_Click(object sender, EventArgs e)
{
    System.IO.DirectoryInfo myDirInfo = new DirectoryInfo(@"" + delete.Text);

    foreach (FileInfo file in myDirInfo.GetFiles())
    {
       file.Delete();
    }
    foreach (DirectoryInfo dir in myDirInfo.GetDirectories())
    {
       dir.Delete(true);
    }
}

IO.Directory.Delete(HttpContext.Current.Server.MapPath(path), True)

此版本不使用递归调用，并解决了只读问题。

public static void EmptyDirectory(string directory)
{
    // First delete all the files, making sure they are not readonly
    var stackA = new Stack<DirectoryInfo>();
    stackA.Push(new DirectoryInfo(directory));

    var stackB = new Stack<DirectoryInfo>();
    while (stackA.Any())
    {
        var dir = stackA.Pop();
        foreach (var file in dir.GetFiles())
        {
            file.IsReadOnly = false;
            file.Delete();
        }
        foreach (var subDir in dir.GetDirectories())
        {
            stackA.Push(subDir);
            stackB.Push(subDir);
        }
    }

    // Then delete the sub directories depth first
    while (stackB.Any())
    {
        stackB.Pop().Delete();
    }
}

private void ClearFolder(string FolderName)
{
    DirectoryInfo dir = new DirectoryInfo(FolderName);

    foreach(FileInfo fi in dir.GetFiles())
    {
        try
        {
            fi.Delete();
        }
        catch(Exception) { } // Ignore all exceptions
    }

    foreach(DirectoryInfo di in dir.GetDirectories())
    {
        ClearFolder(di.FullName);
        try
        {
            di.Delete();
        }
        catch(Exception) { } // Ignore all exceptions
    }
}

如果您知道没有子文件夹，那么像这样的操作可能是最简单的：

    Array.ForEach(Directory.GetFiles(folderName), File.Delete);

这是我看完所有帖子后使用的工具。确实如此

删除所有可以删除的内容如果某些文件保留在文件夹中，则返回false

它处理的是

只读文件删除延迟锁定的文件

它不使用Directory.Delete，因为该进程因异常而中止。

    /// <summary>
    /// Attempt to empty the folder. Return false if it fails (locked files...).
    /// </summary>
    /// <param name="pathName"></param>
    /// <returns>true on success</returns>
    public static bool EmptyFolder(string pathName)
    {
        bool errors = false;
        DirectoryInfo dir = new DirectoryInfo(pathName);

        foreach (FileInfo fi in dir.EnumerateFiles())
        {
            try
            {
                fi.IsReadOnly = false;
                fi.Delete();

                //Wait for the item to disapear (avoid 'dir not empty' error).
                while (fi.Exists)
                {
                    System.Threading.Thread.Sleep(10);
                    fi.Refresh();
                }
            }
            catch (IOException e)
            {
                Debug.WriteLine(e.Message);
                errors = true;
            }
        }

        foreach (DirectoryInfo di in dir.EnumerateDirectories())
        {
            try
            {
                EmptyFolder(di.FullName);
                di.Delete();

                //Wait for the item to disapear (avoid 'dir not empty' error).
                while (di.Exists)
                {
                    System.Threading.Thread.Sleep(10);
                    di.Refresh();
                }
            }
            catch (IOException e)
            {
                Debug.WriteLine(e.Message);
                errors = true;
            }
        }

        return !errors;
    }
