A block collection that contains the Block elements of the ListItem

Use the block collection returned by this property to enumerate or manipulate the contents of a Section element.

These examples demonstrate some of the more common operations that can be performed on flow content elements through the Blocks property. This property is used to add and remove items from BlockCollection. Flow content elements that feature a Blocks property include:

These examples happen to use Section as the flow content element, but these techniques are applicable to all elements that host a flow content element collection.

The following example creates a new Section and then uses the Add method to add a new Paragraph to the Section contents.


Section secx = new Section();
secx.Blocks.Add(new Paragraph(new Run("A bit of text content...")));


The following example creates a new Paragraph element and inserts it at the beginning of the Section.


Paragraph parx = new Paragraph(new Run("Text to insert..."));
secx.Blocks.InsertBefore(secx.Blocks.FirstBlock, parx);


The following example gets the number of top-level Block elements contained in the Section.


int countTopLevelBlocks = secx.Blocks.Count;


The following example deletes the last Block element in the Section.


secx.Blocks.Remove(secx.Blocks.LastBlock);


The following example clears all of the contents (Block elements) from the Section.


secx.Blocks.Clear();
