Adding new line to text property of a label box

In WPF, you can add a new line to the Text property of a Label control by using the \r\n or Environment.NewLine syntax.

Here are a few examples:

1. Using \r\n:

   <Label Content="Line 1\r\nLine 2" />

   This will render as:

Line 1 Line 2

2. Using Environment.NewLine:

   <Label Content="Line 1{Environment.NewLine}Line 2" />

   This will also render as:

Line 1 Line 2

3. Using a TextBlock instead of a Label:

   <TextBlock Text="Line 1" TextWrapping="Wrap">
    <Run Text="Line 2" />
   </TextBlock>

   This will also render as:

Line 1 Line 2

Note that the TextWrapping property is set to Wrap to allow the text to wrap to a new line.

4. Using a StringBuilder to build the text:

   
   string text = "Line 1";
   text += Environment.NewLine;
   text += "Line 2";

Label myLabel = new Label(); myLabel.Content = text;

This will also render as:

Line 1
Line 2
