如何从代码后面将边框背景更改为红色？

<Border Name="border_c"
           HorizontalAlignment="Left"
           VerticalAlignment="Top"
           CornerRadius="10" Width="180" Background="green">

试试这个..

using System.Windows.Media;

Border border = border_c;
SolidColorBrush redBrush = new SolidColorBrush(Colors.Red);
border.Background = redBrush;

或

border_c.Background = Brushes.Red;
