I have stored a text file into isolated storage, my file is saved in a way of "asdasdasd,asdasdasd", how can I use delimiters to spilt them instead of retrieving the whole string like this:

```
        //Get the Store we created earlier
        IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication();
        //use a StreamReader to open and read the file           
        StreamReader readFile = null;
        try
        {
            readFile = new StreamReader(new IsolatedStorageFileStream("SaveFolder\\SavedFile.txt", FileMode.Open, store));
            string fileText = readFile.ReadToEnd();

            //The control txtRead will display the text entered in the file
            textBlock2.Text = fileText;
            readFile.Close();
        }

        catch
        {
            //For now, a simple catch to make sure they created it first
            //we will modify this later
            textBlock2.Text = "Need to create directory and the file first.";
        }

```
