How to put a new line into a wpf TextBlock control?

In WPF, you can insert a new line into a TextBlock control by using the LineBreak element or by adding a newline character (\n) to the text content. Here are two approaches:

  1. Using LineBreak element:

    <TextBlock> Line 1 <LineBreak /> Line 2 </TextBlock>

    In this example, the LineBreak element is placed between the lines of text within the TextBlock. This will create a new line between "Line 1" and "Line 2" when rendered.

  2. Using newline character:

    <TextBlock> Line 1&#x0a;Line 2 </TextBlock>

    In this example, the newline character (&#x0a;) is used to separate the lines of text. This will also produce a new line between "Line 1" and "Line 2" when rendered. The newline character is represented by &#x0a;, which is the Unicode code for a line feed.

Alternatively, if you are setting the text programmatically, you can use the Environment.NewLine constant to insert a new line:

TextBlock textBlock = new TextBlock(); textBlock.Text = "Line 1" + Environment.NewLine + "Line 2";

In this case, Environment.NewLine represents the platform-specific newline sequence (\r\n on Windows, \n on Unix-based systems).

Regardless of the method you choose, the resulting TextBlock will display the text on separate lines, providing the appearance of new lines within the control.
