WPF界面按钮美化

在App.xaml里加入全局按钮样式

　　全局按钮样式是直接针对Button的，所以在界面上直接用

</Window>

　　后台

public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        Button b;

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            if (b != null) b.IsEnabled = true;
            b = sender as Button;
            b.IsEnabled = false;
        }
    }
}
