How to change font color from C# in WPF

How to change font color from C# in WPF

In WPF, you can change the font color of a control by setting its Foreground property to a Brush object that represents the desired color. Here's how to do it in C#:

using System.Windows.Media; // Get a reference to the control you want to change the font color of var myTextBlock = new TextBlock(); // Create a new SolidColorBrush object with the desired color var brush = new SolidColorBrush(Colors.Red); // Set the Foreground property of the control to the new SolidColorBrush myTextBlock.Foreground = brush;

In this example, we are creating a new TextBlock control and setting its Foreground property to a new SolidColorBrush object with the color red. You can replace myTextBlock with a reference to any other control that has a Foreground property, such as a Label, Button, or TextBox.

Note that you can also set the Foreground property directly in XAML using a color name, RGB value, or a resource. For example:

<TextBlock Text="Hello, world!" Foreground="Red" /> 
<TextBlock Text="Hello, world!"> <TextBlock.Foreground> <SolidColorBrush Color="Red" /> </TextBlock.Foreground> </TextBlock> 
<SolidColorBrush x:Key="MyBrush" Color="Red" /> <TextBlock Text="Hello, world!" Foreground="{StaticResource MyBrush}" />

Regardless of whether you set the Foreground property in XAML or in C#, the end result is the same: the font color of the control will be changed to the specified color.
