c# - テキスト ボックスのテキストを IsolatedStorage に保存し、アプリを開くたびにフィールドに入力します

Question

乱数ジェネレーター アプリを作成しました。ユーザーは、min、max、および amount から gen に整数を入力できます。3 つのボタンがあります。出力を生成し、クリアし、保存します。保存以外はすべて動作します。

私はこれに約6時間取り組んでいますが（冗談ではありません）、まだ理解できません。このスレッドを見つけましたが、実装方法がわかりません: How to store a integer value in isolated storage in wp7?

コードは次のとおりです。

            if (IsolatedStorageSettings.ApplicationSettings.Contains("minstorage"))
            {
                min1 = (int)IsolatedStorageSettings.ApplicationSettings["minstorage"];
                string min1text = min1.ToString();

            if (gen > 100) { OutputBox.Text = "You cannot generate more than 100 numbers."; }
            if (gen < 0) { OutputBox.Text = "You cannot generate less than 0 numbers."; }

        //string min1 = MinNumInput.Text;
        //string max1 = MaxNumInput.Text;
        // Store the value
        IsolatedStorageSettings.ApplicationSettings["minstorage"] = min1;
    }

    // Sample code for building a localized ApplicationBar
    //private void BuildLocalizedApplicationBar()
    //{
    //    // Set the page's ApplicationBar to a new instance of ApplicationBar.
    //    ApplicationBar = new ApplicationBar();

    //    // Create a new button and set the text value to the localized string from AppResources.
    //    ApplicationBarIconButton appBarButton = new ApplicationBarIconButton(new Uri("/Assets/AppBar/appbar.add.rest.png", UriKind.Relative));
    //    appBarButton.Text = AppResources.AppBarButtonText;
    //    ApplicationBar.Buttons.Add(appBarButton);

    //    // Create a new menu item with the localized string from AppResources.
    //    ApplicationBarMenuItem appBarMenuItem = new ApplicationBarMenuItem(AppResources.AppBarMenuItemText);
    //    ApplicationBar.MenuItems.Add(appBarMenuItem);
    //}
}

}

誰かが私を助けてくれれば、それは素晴らしいことです。ありがとうございました。
