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;
    }

DirectoryInfo Folder = new DirectoryInfo(Server.MapPath(path)); 
if (Folder .Exists)
{
    foreach (FileInfo fl in Folder .GetFiles())
    {
        fl.Delete();
    }

    Folder .Delete();
}

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

你不需要更多

using System.IO;

string[] filePaths = Directory.GetFiles(@"c:\MyDir\");

foreach (string filePath in filePaths)

File.Delete(filePath);

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);

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);
    }
 }
