Cara: Membaca dan Menulis ke File di Penyimpanan Terisolasi

  • Artikel

Untuk membaca dari, atau menulis ke, file di penyimpanan terisolasi, gunakan IsolatedStorageFileStream objek dengan pembaca aliran (StreamReader objek) atau penulis aliran (StreamWriter objek).

Contoh

Contoh kode berikut mendapatkan penyimpanan terisolasi dan memeriksa apakah file bernama TestStore.txt ada di penyimpanan. Jika tidak ada, itu membuat file dan menulis "Halo Penyimpanan Terisolasi" ke file. Jika TestStore.txt sudah ada, kode contoh membaca dari file.

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

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            IsolatedStorageFile isoStore = IsolatedStorageFile.GetStore(IsolatedStorageScope.User | IsolatedStorageScope.Assembly, null, null);

            if (isoStore.FileExists("TestStore.txt"))
            {
                Console.WriteLine("The file already exists!");
                using (IsolatedStorageFileStream isoStream = new IsolatedStorageFileStream("TestStore.txt", FileMode.Open, isoStore))
                {
                    using (StreamReader reader = new StreamReader(isoStream))
                    {
                        Console.WriteLine("Reading contents:");
                        Console.WriteLine(reader.ReadToEnd());
                    }
                }
            }
            else
            {
                using (IsolatedStorageFileStream isoStream = new IsolatedStorageFileStream("TestStore.txt", FileMode.CreateNew, isoStore))
                {
                    using (StreamWriter writer = new StreamWriter(isoStream))
                    {
                        writer.WriteLine("Hello Isolated Storage");
                        Console.WriteLine("You have written to the file.");
                    }
                }
            }
        }
    }
}

            Console.WriteLine("The file already exists!")
            Using isoStream As IsolatedStorageFileStream = New IsolatedStorageFileStream("TestStore.txt", FileMode.Open, isoStore)
                Using reader As StreamReader = New StreamReader(isoStream)
                    Console.WriteLine("Reading contents:")
                    Console.WriteLine(reader.ReadToEnd())
                End Using

                    writer.WriteLine("Hello Isolated Storage")
