How to put a new line into a wpf TextBlock control

Question

I m fetching text from an XML file  and I d like to insert some new lines that are interpreted by the textblock render as new lines   I ve tried    lt data gt Foo bar baz  n baz bar lt  data gt    But the data is still displayed without the new line  I set the contents of  lt data gt  via the  Text property via C    What do I need to put in the XML in order for it to render the new line in the GUI   I ve tried something like this manually setting the text in the XAML    lt TextBlock Margin  0 15 0 0  Width  600  gt  There  amp  10  is a new line   lt  TextBlock gt    And while the encoded character doesn t appear in the GUI it also doesn t give me a new line

Using System Environment NewLine is the only solution that worked for me  When I tried  r n  it just repeated the actual  r n in the text box

you must use    lt  SomeObject xml space  preserve   gt  once upon a time           this line will be below the first one  lt   SomeObject gt    Or if you prefer      lt SomeObject xml space  preserve    gt   once upon a time     amp  10  this line below  lt    SomeObject gt    watch out   if you both use  amp 10 AND you go to the next line in your text  you ll have TWO empty lines   here for details   http   msdn microsoft com en-us library ms788746 aspx

Even though this is an old question  I ve just come across the problem and solved it differently from the given answers  Maybe it could be helpful to others   I noticed that even though my XML files looked like    lt tag gt    lt subTag gt content with newline  r nto display lt  subTag gt   lt  tag gt    When it was read into my C  code the string had double backslashes     r  n   To fix this I wrote a ValueConverter to strip the extra backslash   public class XmlStringConverter   IValueConverter       public object Convert          object value          Type targetType          object parameter          CultureInfo culture                string valueAsString   value as string          if  string IsNullOrEmpty valueAsString                         return value                     valueAsString   valueAsString Replace    r  n     r n            return valueAsString             public object ConvertBack          object value          Type targetType          object parameter          CultureInfo culture                throw new NotImplementedException

You can try putting a new line in the data    lt data gt Foo bar baz   baz bar lt  data gt    If that does not work you might need to parse the string manually   If you need direct XAML that s easy by the way    lt TextBlock gt      Lorem  lt LineBreak  gt      Ipsum  lt  TextBlock gt

Insert a  line break  or a  paragraph break  in a RichTextBox  rtb  like this   var range   new TextRange rtb SelectionStart  rtb Selection End    range Start Paragraph ContentStart InsertLineBreak    range Start Paragraph ContentStart InsertParagraphBreak      The only way to get the NewLine items is by inserting text with   r n  items first  and then applying more code which works on Selection and or TextRange objects  This makes sure that the  par items are converted to  line items  are saved as desired  and are still correct when reopening the   Rtf file  That is what I found so far after hard tries  My three code lines need to be surrounded by more code  with loops  to set the TextPointer items   Start  End  ContentStart  ContentEnd  where the Lines and Breaks should go  which I have done with success for my purposes
