从主机调用

static void Main(string[] args)
{ 
   string Filepathe =<Your path>
   DeleteDirectory(System.IO.Directory.GetParent(Filepathe).FullName);              
}

添加此方法

public static void DeleteDirectory(string path)
{
    if (Directory.Exists(path))
    {
        //Delete all files from the Directory
        foreach (string file in Directory.GetFiles(path))
        {
            File.Delete(file);
        }
        //Delete all child Directories
        foreach (string directory in Directory.GetDirectories(path))
        {
             DeleteDirectory(directory);
        }
        //Delete a Directory
        Directory.Delete(path);
    }
 }

使用DirectoryInfo的GetDirectories方法。

foreach (DirectoryInfo subDir in new DirectoryInfo(targetDir).GetDirectories())
                    subDir.Delete(true);

在Windows 7中，如果您刚刚使用Windows资源管理器手动创建了它，则目录结构与以下类似：

C:
  \AAA
    \BBB
      \CCC
        \DDD

运行原始问题中建议的代码来清理目录C:\AAA，当尝试删除BBB时，行di.Delete（true）总是失败，并出现IOException“目录不是空的”。这可能是由于Windows资源管理器中的某种延迟/缓存。

以下代码对我来说工作可靠：

static void Main(string[] args)
{
    DirectoryInfo di = new DirectoryInfo(@"c:\aaa");
    CleanDirectory(di);
}

private static void CleanDirectory(DirectoryInfo di)
{
    if (di == null)
        return;

    foreach (FileSystemInfo fsEntry in di.GetFileSystemInfos())
    {
        CleanDirectory(fsEntry as DirectoryInfo);
        fsEntry.Delete();
    }
    WaitForDirectoryToBecomeEmpty(di);
}

private static void WaitForDirectoryToBecomeEmpty(DirectoryInfo di)
{
    for (int i = 0; i < 5; i++)
    {
        if (di.GetFileSystemInfos().Length == 0)
            return;
        Console.WriteLine(di.FullName + i);
        Thread.Sleep(50 * i);
    }
}

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

你不需要更多

 new System.IO.DirectoryInfo(@"C:\Temp").Delete(true);

 //Or

 System.IO.Directory.Delete(@"C:\Temp", true);

这将显示我们如何删除文件夹并使用文本框进行检查

using System.IO;
namespace delete_the_folder
{
public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Deletebt_Click(object sender, EventArgs e)
    {
        //the  first you should write the folder place
        if (Pathfolder.Text=="")
        {
            MessageBox.Show("ples write the path of the folder");
            Pathfolder.Select();
            //return;
        }

        FileAttributes attr = File.GetAttributes(@Pathfolder.Text);

        if (attr.HasFlag(FileAttributes.Directory))
            MessageBox.Show("Its a directory");
        else
            MessageBox.Show("Its a file");

        string path = Pathfolder.Text;
        FileInfo myfileinf = new FileInfo(path);
        myfileinf.Delete();

    }


}
