Gets the number of nodes in the collection.
public int Count { get; }
Examples
Shows how to traverse through a composite node’s collection of child nodes.
Document doc = new Document();
// Add two runs and one shape as child nodes to the first paragraph of this document.
Paragraph paragraph = (Paragraph)doc.GetChild(NodeType.Paragraph, 0, true);
paragraph.AppendChild(new Run(doc, "Hello world! "));
Shape shape = new Shape(doc, ShapeType.Rectangle);
shape.Width = 200;
shape.Height = 200;
// Note that the 'CustomNodeId' is not saved to an output file and exists only during the node lifetime.
shape.CustomNodeId = 100;
shape.WrapType = WrapType.Inline;
paragraph.AppendChild(shape);
paragraph.AppendChild(new Run(doc, "Hello again!"));
// Iterate through the paragraph's collection of immediate children,
// and print any runs or shapes that we find within.
NodeCollection children = paragraph.GetChildNodes(NodeType.Any, false);
Assert.AreEqual(3, paragraph.GetChildNodes(NodeType.Any, false).Count);
foreach (Node child in children)
switch (child.NodeType)
{
case NodeType.Run:
Console.WriteLine("Run contents:");
Console.WriteLine($"\t\"{child.GetText().Trim()}\"");
break;
case NodeType.Shape:
Shape childShape = (Shape)child;
Console.WriteLine("Shape:");
Console.WriteLine($"\t{childShape.ShapeType}, {childShape.Width}x{childShape.Height}");
break;
}
Shows how to find out if a tables are nested.
public void CalculateDepthOfNestedTables()
{
Document doc = new Document(MyDir + "Nested tables.docx");
NodeCollection tables = doc.GetChildNodes(NodeType.Table, true);
for (int i = 0; i < tables.Count; i++)
{
Table table = (Table)tables[i];
// Find out if any cells in the table have other tables as children.
int count = GetChildTableCount(table);
Console.WriteLine("Table #{0} has {1} tables directly within its cells", i, count);
// Find out if the table is nested inside another table, and, if so, at what depth.

if (tableDepth > 0)
Console.WriteLine("Table #{0} is nested inside another table at depth of {1}", i,
tableDepth);
else
Console.WriteLine("Table #{0} is a non nested table (is not a child of another table)", i);
