Windows Phone 独立存储（IsolatedStorageFile） 简单

       private void IsolatedStorageFileDemo()
        {

            string isolatedFileName = "DemoIsolatedFile.txt"; //文件名
            IsolatedStorageFile isoStore;  
            IsolatedStorageFileStream isoStream;

            StreamWriter myWrite;  //写
            StreamReader myReader; //读

            string lineFormIsolatedFile;

            isoStore = IsolatedStorageFile.GetUserStoreForApplication(); //取得用户Application的地址

            //打开指定的文件，以创建的方式
            isoStream = new IsolatedStorageFileStream(isolatedFileName,FileMode.Create,isoStore);


            //写入文件
            myWrite = new StreamWriter(isoStream);
            myWrite.WriteLine("Writing to isolated storage files is easy!");
            myWrite.WriteLine("It is also secure and stable.");
            myWrite.Close();

            //读取文件
            isoStream = new IsolatedStorageFileStream(isolatedFileName,FileMode.Open, isoStore);
            myReader = new StreamReader(isoStream);
            while ((lineFormIsolatedFile = myReader.ReadLine()) != null)
            {
                //Console.WriteLine(lineFormIsolatedFile);
                MessageBox.Show(lineFormIsolatedFile);
            }
            myReader.Close();
        }
