这是我的滑块：这是我的滑块： <Slider x:Name="videoPlayerSlider" Minimum="0" Maximum="100" HorizontalAlignment="Stretch" VerticalAlignment="Bottom" Thumb.DragStarted="OnSliderDragStarted_Click"

为什么我无法像在 XAML 上那样在代码后面绑定 StringFormat？

这是我的工作示例，它正确绑定了 ViewModel 并正确触发了 StringFormat 和 ValidateMaskDecimal：这是我的工作示例，它正确绑定了 ViewModel 并正确触发 StringFormat 和 ValidateMaskDecimal: <ListBox x:Name="Difetti" ItemsSource="{Binding Difetti}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <TextBox x:Name="Metro" controls:TextBoxHelper.Watermark="Metro" PreviewTextInput="ValidateMaskDecimal"> <TextBox.Text> <Binding Path="Metro" StringFormat="{}{0:0.0##########}"> </Binding> </TextBox.Text> </TextBox> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> 现在，如果我尝试在后面的代码中执行类似的操作（删除 ListBox，并将唯一的 TextBox 绑定到某个特定 index = 0 处的数据模型）： <TextBox x:Name="Metro" controls:TextBoxHelper.Watermark="Metro" PreviewTextInput="ValidateMaskDecimal" /> var data = DataContext as ViewModelData; if (data != null && data.Difetti.Count > 0) { int difettoIndex = 0; Metro.SetBinding(TextBox.TextProperty, new Binding { Source = data, Path = new PropertyPath($"Difetti[{difettoIndex}].Metro"), StringFormat = "{}{0:0.0##########}" }); } 它会抛出 ValueStringBuilder 的 ThrowFormatError 异常： System.FormatException: '输入字符串的格式不正确。'. 我不明白为什么。我哪里错了？代码不应该给我同样的结果吗？ DataModel 上的 Metro 以这种方式配置（可空 decimal）： private decimal? metro; public decimal? Metro { get { return metro; } set { SetField(ref metro, value, "Metro"); } } 字符串格式前缀的 {} 特定于 XAML。您在代码中不需要它。当然，您可以检查在XAML中创建的字符串格式文本。 BindingExpression expression = BindingOperations.GetBindingExpression(Metro, TextBox.TextProperty); string format = expression.ParentBinding.StringFormat; Debug.WriteLine(format);
