1. Custom style button

two。 The converter is used to bind buttons

Public class FontConverters: IValueConverter {public object Convert (object value, Type targetType, object parameter, CultureInfo culture) {if (value! = null & & bool.TryParse (value.ToString (), out bool result)) {if (result) {return "close serial port" }} return "open serial port";} public object ConvertBack (object value, Type targetType, object parameter, CultureInfo culture) {throw new NotImplementedException () }} / / the color state used to bind UI shows public class ColorConverters: IValueConverter {public object Convert (object value, Type targetType, object parameter, CultureInfo culture) {if (value! = null & & bool.TryParse (value.ToString ()) Out bool result) {if (result) {return new SolidColorBrush ((Color) System.Windows.Media.ColorConverter.ConvertFromString ("# 2E8B57")) } return new SolidColorBrush ((Color) System.Windows.Media.ColorConverter.ConvertFromString ("# FF6347"));} public object ConvertBack (object value, Type targetType, object parameter, CultureInfo culture) {throw new NotImplementedException ();}}

3. Reference font

4. Bind commands and elements
