如何：在独立存储中删除文件和目录

using System;
using System.IO.IsolatedStorage;
using System.IO;

public class DeletingFilesDirectories{

   public static void Main(){

      // Get a new isolated store for this user domain and assembly.
      // Put the store into an isolatedStorageFile object.

      IsolatedStorageFile isoStore =  IsolatedStorageFile.GetStore(IsolatedStorageScope.User | IsolatedStorageScope.Domain | IsolatedStorageScope.Assembly, null, null);
    
      Console.WriteLine("Creating Directories:");

      // This code creates several different directories.

      isoStore.CreateDirectory("TopLevelDirectory");
      Console.WriteLine("TopLevelDirectory");
      isoStore.CreateDirectory("TopLevelDirectory/SecondLevel");
      Console.WriteLine("TopLevelDirectory/SecondLevel");

      // This code creates two new directories, one inside the other.

      isoStore.CreateDirectory("AnotherTopLevelDirectory/InsideDirectory");
      Console.WriteLine("AnotherTopLevelDirectory/InsideDirectory");
      Console.WriteLine();

      // This code creates a few files and places them in the directories.

      Console.WriteLine("Creating Files:");

      // This file is placed in the root.

      IsolatedStorageFileStream isoStream1 = new IsolatedStorageFileStream("InTheRoot.txt", FileMode.Create, isoStore);
      Console.WriteLine("InTheRoot.txt");
  
      isoStream1.Close();

      // This file is placed in the InsideDirectory.

      IsolatedStorageFileStream isoStream2 = new IsolatedStorageFileStream("AnotherTopLevelDirectory/InsideDirectory/HereIAm.txt", FileMode.Create, isoStore);
      Console.WriteLine("AnotherTopLevelDirectory/InsideDirectory/HereIAm.txt");
      Console.WriteLine();

      isoStream2.Close();

      Console.WriteLine("Deleting File:");

      // This code deletes the HereIAm.txt file.
      isoStore.DeleteFile("AnotherTopLevelDirectory/InsideDirectory/HereIAm.txt");
      Console.WriteLine("AnotherTopLevelDirectory/InsideDirectory/HereIAm.txt"); 
      Console.WriteLine();

      Console.WriteLine("Deleting Directory:");

      // This code deletes the InsideDirectory.

      isoStore.DeleteDirectory("AnotherTopLevelDirectory/InsideDirectory/");
      Console.WriteLine("AnotherTopLevelDirectory/InsideDirectory/");
      Console.WriteLine();

   }// End of main.
