我有一個主要的應用程序在這有邊框不同的按鈕。這還包括「Einstellung」按鈕。按此按鈕應顯示與以前不同的內容。這是我用UserControl實現的。C＃WPF在UserControl中的應用程序保存設置
現在您可以在此用戶控件中進行設置並保存它們。
這節省我的設置
和守則
Vorschau.Properties.Settings.Default.BreiteBitmap = Int32.Parse(tbBreiteBitmap.Text);
Vorschau.Properties.Settings.Default.HoeheBitmap = Int32.Parse(tbHoeheBitmap.Text);
Vorschau.Properties.Settings.Default.AnzahlKoordinaten = Int32.Parse(tbAnzahlKoordinaten.Text);
由現在我按下 「Speichern」 按鈕。他爲我節省了設置。 我現在改變UserControl，所以我點擊一個按鈕「Vorschau」，並向我顯示一個新的內容。如果我現在再次點擊「Einstellung」，那麼內容仍然存在，因爲我已經存儲了它。
但問題來了。我關閉了應用程序，然後再次打開它。現在我點擊文本框中的按鈕「Einstellung」，它只是處處是0。
這不應該是這樣的，但內容應該是從那裏過去。
我在啓動應用程序時檢索此內容。查看代碼片段。
public UCEinstellung()
{
InitializeComponent();
//Lade der Einstellungen
tbBreiteBitmap.Text = Vorschau.Properties.Settings.Default.BreiteBitmap.ToString();
tbHoeheBitmap.Text = Vorschau.Properties.Settings.Default.HoeheBitmap.ToString();
tbAnzahlKoordinaten.Text = Vorschau.Properties.Settings.Default.AnzahlKoordinaten.ToString();
}
和
public MainWindow()
{
InitializeComponent();
MouseDown += Window_MouseDown;
einstellung.tbBreiteBitmap.Text = Vorschau.Properties.Settings.Default.BreiteBitmap.ToString();
einstellung.tbHoeheBitmap.Text = Vorschau.Properties.Settings.Default.HoeheBitmap.ToString();
einstellung.tbAnzahlKoordinaten.Text = Vorschau.Properties.Settings.Default.AnzahlKoordinaten.ToString();
}
可惜，這是行不通的。 我希望你能告訴我錯誤在哪裏。在沒有用戶控制的另一個應用程序中，這個存儲和檢索正確。
