删除目录时提示"目录不为空"该怎么解决

删除目录时提示"目录不为空"
C#下，用Directory.Delete(path,true)删除时，提示这个错误。
例如：目录为F:\Mp\test\127.0.0.1\%e7%ae%a1%e7%90%86%e5%91%98\temp(temp下有文件)的时候，当提示这个错误的时候，F:\Mp\test\127.0.0.1\%e7%ae%a1%e7%90%86%e5%91%98目录还存在，但是我是希望将\%e7%ae%a1%e7%90%86%e5%91%98这个目录也删除的.

用递归删除
[解决办法]
可能是因为文件夹中有文件吧，要用递归删除整个文件夹，或者用用我这个类(C#整个目录拷贝与删除的类)：

C# code

using System;using System.Collections;using System.Windows.Forms;using System.IO;namespace DYBC{                public class FileExec        {                public FileExec()                {                }                                private static void CopyDirectory(DirectoryInfo OldDirectory, DirectoryInfo NewDirectory)                {                        string NewDirectoryFullName = NewDirectory.FullName + @"\" + OldDirectory.Name;                        if ( !Directory.Exists(NewDirectoryFullName) )                                Directory.CreateDirectory(NewDirectoryFullName);                                                FileInfo[] OldFileAry = OldDirectory.GetFiles();                        foreach (FileInfo aFile in OldFileAry)                                 File.Copy(aFile.FullName, NewDirectoryFullName +  @"\" +  aFile.Name, true);                        DirectoryInfo[]        OldDirectoryAry = OldDirectory.GetDirectories();                        foreach ( DirectoryInfo aOldDirectory in OldDirectoryAry )                        {                                DirectoryInfo aNewDirectory = new DirectoryInfo(NewDirectoryFullName);                                CopyDirectory(aOldDirectory, aNewDirectory);                        }                }                //CopyDirectory                public static void CopyDirectory(string OldDirectoryStr, string NewDirectoryStr)                {                        DirectoryInfo OldDirectory = new DirectoryInfo( OldDirectoryStr );                        DirectoryInfo NewDirectory = new DirectoryInfo( NewDirectoryStr );                                FileExec.CopyDirectory(OldDirectory,NewDirectory);                }                //DelDirectory                public static void DelDirectory(string OldDirectoryStr)                {                        DirectoryInfo OldDirectory = new DirectoryInfo( OldDirectoryStr );                        OldDirectory.Delete(true);                }                //CopyDirectory And DelDirectory                public static void CopyAndDelDirectory(string OldDirectory, string NewDirectory)                {                        CopyDirectory( OldDirectory,NewDirectory);                        DelDirectory(  OldDirectory );                }        }}

用递归法删除.
DirectoryInfo dir = new DirectoryInfo(path);
           DirectoryInfo[] childADir=dir.GetDirectories();
           FileInfo[] childAFiles = dir.GetFiles();

           if (childAFiles.Length > 0)
           {
               for (int j = 0; j < childAFiles.Length; j++)
               {
                   string newFilePath = path + @"\" + childAFiles[j].Name.ToString();
                   File.Delete(newFilePath);
               }
           }
           if (childADir.Length > 0)
           {
               for (int i = 0; i < childADir.Length; i++)
               {
                   string newPath = path + @"\" + childADir[i].Name.ToString();
                   DelDir(newPath);
               }
           }
