Question

I’m writting a program in .Net for Windows Phone 7.

I have a part code:

public void deSerialize()
    {
        sr = new StreamReader(new IsolatedStorageFileStream("Data\\myFile.txt", FileMode.Open, myFile));
        DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(RootObject));
        string text = sr.ReadToEnd();
        Stream strm = File.OpenRead("Data\\myFile.txt");
        menetrend = serializer.ReadObject(strm) as RootObject;
    }

My problem is in here:

Stream strm = File.OpenRead(“Data\myFile.txt”);

The complier cannot see the myFile.txt and I don’t know how can I solve the problem.

Something I would definitely look into is it looks like you are trying to open up too streams one via File and one using IsolatedStorageStream. As @PhilBolduc said you need to use IsolatedStorageStream. I would also like to make a suggestion and use using statements when accesing streams so they dispose of themselves.

    using (var isoFileStream = new IsolatedStorageFileStream(filePath, FileMode.OpenOrCreate, storage))
    {
    }
