C# 泛型字典验证控件输入 - 使用 Dictionary<Type, Func<FrameworkElement, bool>>

Dictionary<Type, Func<FrameworkElement, bool>> validationMethods = new Dictionary<Type, Func<FrameworkElement, bool>>() { { typeof(TextBox), (element) => !string.IsNullOrEmpty(((TextBox)element).Text) }, { typeof(ComboBox), (element) => !string.IsNullOrEmpty(((ComboBox)element).Text) }, { typeof(DatePicker), (element) => !string.IsNullOrEmpty(((DatePicker)element).Text) } };

foreach (var element in Panel.Children.OfType()) { if (validationMethods.TryGetValue(element.GetType(), out var validationMethod)) { if (!validationMethod(element)) { return false; // 如果验证失败，则返回 false } } }
