<pre><code>textBox1.Background = Brushes.Blue;
textBox1.Foreground = Brushes.Yellow;

WPF Foreground and Background is of type <code>System.Windows.Media.Brush</code>. You can set another color like this:

<pre><code>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;
</code></pre>

entityMap|blocks|key|2muo3|text|我猜你是在用XAML创建TextBox吧？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|131j1|在这种情况下，您需要为文本框指定一个名称。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：|6u444|myTextBox.Background+=+new+SolidColorBrush(Colors.White);|code-block|syntax|javascript^0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|J|9|@]|A|@]|B|$]]|$2|C|4|D|6|7|8|K|9|@]|A|@]|B|$]]|$2|E|4|F|6|G|8|L|9|@]|A|@]|B|$H|I]]]]

I take it you are creating the TextBox in XAML?

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:

<pre><code>myTextBox.Background = new SolidColorBrush(Colors.White);
</code></pre>

entityMap|blocks|key|bjrk1|text|你有没有看过Color.FromRgb?|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data^0|6|D^^$0|$]|1|@$2|3|4|5|6|7|8|G|9|@$A|H|B|I|C|D]]|E|@]|F|$]]]]

Have you taken a look at <code>Color.FromRgb</code>?

entityMap|blocks|key|1gvb7|text|如果你想使用十六进制颜色设置背景，你可以这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4q16k|var+bc+=+new+BrushConverter();

myTextBox.Background+=+(Brush)bc.ConvertFrom("#FFXXXXXX");|code-block|syntax|javascript|c3t8n|或者，您可以在XAML中设置SolidColorBrush资源，然后在代码隐藏中使用findResource：|4v1f9|#FF8D8A8A
myTextBox.Background+=+(Brush)Application.Current.MainWindow.FindResource("BrushFFXXXXXX");^0|0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|L|9|@]|A|@]|B|$]]|$2|C|4|D|6|E|8|M|9|@]|A|@]|B|$F|G]]|$2|H|4|I|6|7|8|N|9|@]|A|@]|B|$]]|$2|J|4|K|6|E|8|O|9|@]|A|@]|B|$F|G]]]]

If you want to set the background using a hex color you could do this:

<pre><code>var bc = new BrushConverter();

myTextBox.Background = (Brush)bc.ConvertFrom("#FFXXXXXX");
</code></pre>

Or you could set up a SolidColorBrush resource in XAML, and then use findResource in the code-behind:

<pre><code>&lt;SolidColorBrush x:Key="BrushFFXXXXXX"&gt;#FF8D8A8A&lt;/SolidColorBrush&gt;
myTextBox.Background = (Brush)Application.Current.MainWindow.FindResource("BrushFFXXXXXX");
</code></pre>

entityMap|blocks|key|5netq|text|您可以将十六进制转换为RGB：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|ad9p3|string+ccode+=+"#00FFFF00";

You can convert hex to RGB:

<pre><code>string ccode = "#00FFFF00";
int argb = Int32.Parse(ccode.Replace("#", ""), NumberStyles.HexNumber);
Color clr = Color.FromArgb(argb);
</code></pre>

entityMap|blocks|key|bi6tc|text|您可以使用十六进制颜色：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|8hm53|your_contorl.Color+=+DirectCast(ColorConverter.ConvertFromString("#D8E0A627"),+Color)|code-block|syntax|javascript^0|0^^$0|$]|1|@$2|3|4|5|6|7|8|H|9|@]|A|@]|B|$]]|$2|C|4|D|6|E|8|I|9|@]|A|@]|B|$F|G]]]]

You can use hex colors:

<pre><code>your_contorl.Color = DirectCast(ColorConverter.ConvertFromString("#D8E0A627"), Color)
</code></pre>

entityMap|blocks|key|9ng3d|text|我知道这个问题已经在另一篇SOF帖子中得到了回答。但是，如果您知道十六进制，则可以这样做。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|b32j2|textBox1.Background+=+(SolidColorBrush)new+BrushConverter().ConvertFromString("#082049");|code-block|syntax|javascript^0|0^^$0|$]|1|@$2|3|4|5|6|7|8|H|9|@]|A|@]|B|$]]|$2|C|4|D|6|E|8|I|9|@]|A|@]|B|$F|G]]]]

I know this has been answered in another SOF post. However, you could do this if you know the hexadecimal.
<pre><code>textBox1.Background = (SolidColorBrush)new BrushConverter().ConvertFromString(&quot;#082049&quot;);
</code></pre>
