You cannot access the .NET objects and extensions that are not part of WinRT.  See this for available system.io namespace objects and methods: http://msdn.microsoft.com/en-us/library/windows/apps/hh454050.aspx

i have a list view that i want save it to a txt file in window store C#

i write this code for it

private async void Button_Click(object sender, RoutedEventArgs e)
        {
                        string fileName = "test.txt";
            string text = ageTextBox.Text;

            IStorageFolder applicationFolder = ApplicationData.Current.LocalFolder;

            IStorageFile storageFile = await applicationFolder.CreateFileAsync(fileName, CreationCollisionOption.ReplaceExisting);

            using (Stream stream = await storageFile.OpenStreamForWriteAsync())
            {
                byte[] content = Encoding.UTF8.GetBytes(text);
                await stream.WriteAsync(content, 0, content.Length);
            }
