Remarks

The Run and LineBreak objects are the basic content units of a text block. To format the text in a text block, you can apply formatting to various Run objects. The Inlines property of a TextBlock object is an InlineCollection that holds the text block contents.

A Run is also used in the Paragraph and RichTextBox content model.

Any text in the inner text of a XAML TextBlock object element is implicitly converted to a Run object and stored in the TextBlock.Inlines property collection.

You can name a Run (or any other TextElement) by using the Name property or x:Name in XAML. Naming a Run enables you to make changes programmatically. For example, you can change the text dynamically or reorder a text element collection.
