textBox1.Background = Brushes.Blue;
textBox1.Foreground = Brushes.Yellow;
WPF Foreground and Background is of type System.Windows.Media.Brush. You can set another color like this:
WPF 前景和背景是类型System.Windows.Media.Brush。您可以像这样设置另一种颜色：
using System.Windows.Media;
textBox1.Background = Brushes.White;
textBox1.Background = new SolidColorBrush(Colors.White);
textBox1.Background = new SolidColorBrush(Color.FromArgb(0xFF, 0xFF, 0, 0));
textBox1.Background = System.Windows.SystemColors.MenuHighlightBrush;

I take it you are creating the TextBox in XAML?
我认为您是在 XAML 中创建 TextBox 吗？
In that case, you need to give the text box a name. Then in the code-behind you can then set the Background property using a variety of brushes. The simplest of which is the SolidColorBrush:
在这种情况下，您需要为文本框命名。然后在代码隐藏中，您可以使用各种画笔设置背景属性。其中最简单的是 SolidColorBrush：
myTextBox.Background = new SolidColorBrush(Colors.White);

Have you taken a look at Color.FromRgb?
你看了Color.FromRgb吗？

If you want to set the background using a hex color you could do this:
如果你想使用十六进制颜色设置背景，你可以这样做：
var bc = new BrushConverter();
myTextBox.Background = (Brush)bc.ConvertFrom("#FFXXXXXX");
Or you could set up a SolidColorBrush resource in XAML, and then use findResource in the code-behind:
或者您可以在 XAML 中设置 SolidColorBrush 资源，然后在代码隐藏中使用 findResource：
<SolidColorBrush x:Key="BrushFFXXXXXX">#FF8D8A8A</SolidColorBrush>
myTextBox.Background = (Brush)Application.Current.MainWindow.FindResource("BrushFFXXXXXX");

You can convert hex to RGB:
您可以将十六进制转换为 RGB：
string ccode = "#00FFFF00";
int argb = Int32.Parse(ccode.Replace("#", ""), NumberStyles.HexNumber);
Color clr = Color.FromArgb(argb);

You can use hex colors:
您可以使用十六进制颜色：
your_contorl.Color = DirectCast(ColorConverter.ConvertFromString("#D8E0A627"), Color)
