ToArray

NodeCollection.ToArray method

Copies all nodes from the collection to a new array of nodes.

public Node[] ToArray()

Return Value

An array of nodes.

Remarks

You should not be adding/removing nodes while iterating over a collection of nodes because it invalidates the iterator and requires refreshes for live collections.

To be able to add/remove nodes during iteration, use this method to copy nodes into a fixed-size array and then iterate over the array.

Examples

Shows how to replace all textbox shapes with image shapes.

Document doc = new Document(MyDir + "Textboxes in drawing canvas.docx");

Shape[] shapes = doc.GetChildNodes(NodeType.Shape, true).OfType<Shape>().ToArray();

Assert.AreEqual(3, shapes.Count(s => s.ShapeType == ShapeType.TextBox));
Assert.AreEqual(1, shapes.Count(s => s.ShapeType == ShapeType.Image));

foreach (Shape shape in shapes)
{
    if (shape.ShapeType == ShapeType.TextBox)
    {
        Shape replacementShape = new Shape(doc, ShapeType.Image);
        replacementShape.ImageData.SetImage(ImageDir + "Logo.jpg");
        replacementShape.Left = shape.Left;
        replacementShape.Top = shape.Top;
        replacementShape.Width = shape.Width;
        replacementShape.Height = shape.Height;
        replacementShape.RelativeHorizontalPosition = shape.RelativeHorizontalPosition;
        replacementShape.RelativeVerticalPosition = shape.RelativeVerticalPosition;
        replacementShape.HorizontalAlignment = shape.HorizontalAlignment;
        replacementShape.VerticalAlignment = shape.VerticalAlignment;
        replacementShape.WrapType = shape.WrapType;
        replacementShape.WrapSide = shape.WrapSide;

        shape.ParentNode.InsertAfter(replacementShape, shape);
        shape.Remove();
    }
}

shapes = doc.GetChildNodes(NodeType.Shape, true).OfType<Shape>().ToArray();

Assert.AreEqual(0, shapes.Count(s => s.ShapeType == ShapeType.TextBox));
Assert.AreEqual(4, shapes.Count(s => s.ShapeType == ShapeType.Image));

doc.Save(ArtifactsDir + "Shape.ReplaceTextboxesWithImages.docx");
