How to read/write byte[] into Isolated storage

Can anyone tell me how to read开发者_StackOverflow and write byte array into Isolated Storage file in WP7?

---

IsolatedStorageFileSystem has a method for writing byte arrays:

public override void Write(byte[] buffer, int offset, int count);

It can be used as follows:

  byte[] myByteArray = ...
  using (var store = IsolatedStorageFile.GetUserStoreForApplication())
  using (var stream = new IsolatedStorageFileStream("filename.txt",
                 FileMode.Create, FileAccess.Write, store))
  {
      stream.Write(myByteArray, 0, myByteArray.Length);
  }
