ExpandedRemarks

A list in a Microsoft Word document is a set of list formatting properties. Each list can have up to 9 levels and formatting properties, such as number style, start value, indent, tab position etc are defined separately for each level.

A List object always belongs to the ListCollection collection.

To create a new list, use the Add methods of the ListCollection collection.

To modify formatting of a list, use ListLevel objects found in the ListLevels collection.

To apply or remove list formatting from a paragraph, use ListFormat.

ExpandedExamples

Shows how to restart numbering in a list by copying a list.
Document doc = new Document();

// A list allows us to organize and decorate sets of paragraphs with prefix symbols and indents.
// We can create nested lists by increasing the indent level. 
// We can begin and end a list by using a document builder's "ListFormat" property. 
// Each paragraph that we add between a list's start and the end will become an item in the list.
// Create a list from a Microsoft Word template, and customize its first list level.
List list1 = doc.Lists.Add(ListTemplate.NumberArabicParenthesis);

// Apply our list to some paragraphs.

// We can add a copy of an existing list to the document's list collection
// to create a similar list without making changes to the original.
