Create Directory in your Isolated Storage File

<source lang="csharp">using System; using System.IO; using System.IO.IsolatedStorage; static class MainClass {

   static void Main()
   {
       using (IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForAssembly())
       {
           store.CreateDirectory("MyFolder");
           Console.WriteLine("Current size: " + store.CurrentSize.ToString());
           Console.WriteLine("Scope: " + store.Scope.ToString());
       }
   }

}</source>

Current size: 2048
Scope: User, Assembly

Get included files in your Isolated Storage File

<source lang="csharp">using System; using System.IO; using System.IO.IsolatedStorage; static class MainClass {

   static void Main()
   {
       using (IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForAssembly())
       {
           Console.WriteLine("Contained files include:");
           string[] files = store.GetFileNames("*.*");
           foreach (string file in files)
           {
               Console.WriteLine(file);
           }
       }
   }

}</source>

Contained files include:
MyFile.txt

Open up isolated storage based on identity of user + assembly evidence

<source lang="csharp">using System; using System.Collections.Generic; using System.ruponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.IO; using System.IO.IsolatedStorage; using System.Security.Permissions; [assembly: IsolatedStorageFilePermission(SecurityAction.RequestMinimum, UsageAllowed = IsolatedStorageContainment.AssemblyIsolationByUser)] public class MainClass{

   public static void Main()
   {
     using (IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForAssembly())
     {
       using (IsolatedStorageFileStream isStream = new IsolatedStorageFileStream("MyData.txt",FileMode.OpenOrCreate, store))
       {
         using (StreamWriter sw = new StreamWriter(isStream))
         {
           sw.WriteLine("This is my data.");
           sw.WriteLine("Cool, huh?");
         }
       }
     }
   }

}</source>

Read from IsolatedStorage

<source lang="csharp">using System; using System.Collections.Generic; using System.IO; using System.IO.IsolatedStorage; using System.Text;

   public class Tester
   {
       public static void Main()
       {
           Tester app = new Tester();
           app.Run();
       }
       private void Run()
       {
           IsolatedStorageFileStream configFile = new IsolatedStorageFileStream("Tester.cfg", FileMode.Open);
           StreamReader reader = new StreamReader(configFile);
           string theEntry;
           do
           {
               theEntry = reader.ReadLine();
               Console.WriteLine(theEntry);
           } while (theEntry != null);
           reader.Close();
           configFile.Close();
       }
   }</source>

Read text in From IsoStorage

<source lang="csharp">using System; using System.IO.IsolatedStorage; using System.IO;

 class MainClass
 {
   static void Main(string[] args)
   {
     using (IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForAssembly())
     {
       using (IsolatedStorageFileStream isStream = new IsolatedStorageFileStream("MyData.txt", FileMode.Open,FileAccess.Read, store))
       {
         using (StreamReader sr = new StreamReader(isStream))
         {
           string allTheData = sr.ReadToEnd();
           Console.WriteLine(allTheData);
         }
       }
     }

   }

Save file to Isolated Storage File

<source lang="csharp">using System; using System.IO; using System.IO.IsolatedStorage; static class MainClass {

   static void Main()
   {
       using (IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForAssembly())
       {
           store.CreateDirectory("MyFolder");
           using (Stream fs = new IsolatedStorageFileStream("MyFile.txt", FileMode.Create, store))
           {
               StreamWriter w = new StreamWriter(fs);
               w.WriteLine("Test");
               w.Flush();
           }
       }
   }

}</source>

Write text out To IsoStorage

<source lang="csharp">using System; using System.IO.IsolatedStorage; using System.IO;

 class MainClass
 {
   static void Main(string[] args)
   {
     using (IsolatedStorageFile store =IsolatedStorageFile.GetUserStoreForAssembly())
     {
       using (IsolatedStorageFileStream isStream = new IsolatedStorageFileStream("MyData.txt",FileMode.OpenOrCreate, store))
       {
         using (StreamWriter sw = new StreamWriter(isStream))
         {
           sw.WriteLine("data.");
           sw.WriteLine("Cool?");
         }
       }
     }

Writing To Isolated Storage

<source lang="csharp">using System; using System.Collections.Generic; using System.IO; using System.IO.IsolatedStorage; using System.Text;

   public class Tester

           StreamWriter writer = new StreamWriter(configFile);
           String output;
           System.DateTime currentTime = System.DateTime.Now;
           output = "Last access: " + currentTime.ToString();
           writer.WriteLine(output);
           output = "Last position = 27,35";
           writer.WriteLine(output);
           writer.Close();
           configFile.Close();
       }
