Use System.Drawing.Color to set background and foreground in WPF
提问by user2330678
How can I set background and foreground properties of WPF textblocks, using a System.Drawing.Color programmatically ? A solution without a converter would be nice.
如何使用 System.Drawing.Color 以编程方式设置 WPF 文本块的背景和前景属性？没有转换器的解决方案会很好。
System.Drawing.Color BackColor = System.Drawing.Color.Black;
System.Drawing.Color ForeColor = System.Drawing.Color.White;
TextBlock txt = new TextBlock ();
txt.Background=BackColor ;
txt.ForeGround=ForeColor ;
PS: The color I would be assigining would be from a windows forms app and hence it would be a System.Drawing.Color not a System.Windows.Media.Color as required by WPF.
PS：我要分配的颜色将来自 Windows 窗体应用程序，因此它将是 System.Drawing.Color 而不是 WPF 要求的 System.Windows.Media.Color。

You might do it like this:
你可以这样做：
System.Drawing.Color BackColor = System.Drawing.Color.Black;
txt.Background = new SolidColorBrush(
Color.FromArgb(BackColor.A, BackColor.R, BackColor.G, BackColor.B));

You need to use a Brushrather than an Color.
您需要使用 aBrush而不是Color。
There are several predefined brushes so you could do this:
有几个预定义的画笔，所以你可以这样做：
txt.Background = Brushes.Black;
txt.Foreground = Brushes.White;
However, as you are reading the colour from a Windows Form App then you'll have to create your Brushfrom the component colours:
但是，当您从 Windows 窗体应用程序读取颜色时，您必须Brush从组件颜色创建您的颜色：
txt.Background = new SolidColorBrush(Color.FromArgb(BackColor.A, BackColor.R, BackColor.G, BackColor.B));
