Count

NodeCollection.Count property

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.ChildNodes;

Assert.AreEqual(3, paragraph.ChildNodes.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}");
    }

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.
        int tableDepth = GetNestedDepthOfTable(table);

        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);
    }
}

/// <summary>
/// Calculates what level a table is nested inside other tables.
/// </summary>
/// <returns>
/// An integer indicating the nesting depth of the table (number of parent table nodes).
/// </returns>
private static int GetNestedDepthOfTable(Table table)
{
    int depth = 0;
    Node parent = table.GetAncestor(table.NodeType);

    while (parent != null)
    {
        depth++;
        parent = parent.GetAncestor(typeof(Table));
    }

    return depth;
}

/// <summary>

private static int GetChildTableCount(Table table)
{
    int childTableCount = 0;

    foreach (Row row in table.Rows.OfType<Row>())
    {
        foreach (Cell Cell in row.Cells.OfType<Cell>())
        {
            TableCollection childTables = Cell.Tables;

            if (childTables.Count > 0)
                childTableCount++;
        }
    }

    return childTableCount;
}
