如何从Xamarin表单的标签字段中读取文本值

Question

我已将文本分配给标签控件，并且尝试读取控件的文本值，如下所示，

private DataTemplate GetDataTemplate()
    {
        var dataTemplate = new DataTemplate(() =>
        {
            var rowGrid = new Grid
            {
                HorizontalOptions = LayoutOptions.FillAndExpand,
                VerticalOptions = LayoutOptions.FillAndExpand,
                ColumnSpacing = 15,
                Margin = new Thickness(5),
                BackgroundColor = Constants.BackgroundColor
            };

    // Some code

            var isPaymentPlanEnding = new Label { };

            isPaymentPlanEnding.SetBinding(Label.TextProperty, "IsPaymentPlanEnding");


            if (isPaymentPlanEnding.Text.ToLower() == "true")
            {
                var highlightBoxView = new BoxView
                {
                    BackgroundColor = Constants.MMSGErrorRed
                };

                highlightGrid.Children.Add(highlightBoxView);
                highlightGrid.Children.Add(rowGrid);

                return new ViewCell { View = highlightGrid };
            }
            else
            {
                return new ViewCell { View = rowGrid };
            }
        });

        return dataTemplate;
    }

请让我知道，如何从标签控件中读取值。
