| [AddChild](../../aspose.cells.drawing.equations/equationnode/addchild/#addchild)(EquationNodeType) | Insert a node of the specified type at the end of the child node list of the current node. |
| override [Equals](../../aspose.cells.drawing.equations/equationnode/equals/)(object) | Determine whether the current equation node is equal to the specified node |
| [GetChild](../../aspose.cells.drawing.equations/equationnode/getchild/)(int) | Returns the node at the specified index among the children of the current node. |
| [InsertAfter](../../aspose.cells.drawing.equations/equationnode/insertafter/)(EquationNodeType) | Inserts the specified node after the current node. |
| [InsertBefore](../../aspose.cells.drawing.equations/equationnode/insertbefore/)(EquationNodeType) | Inserts the specified node before the current node. |
| [InsertChild](../../aspose.cells.drawing.equations/equationnode/insertchild/)(int, EquationNodeType) | Inserts a node of the specified type at the specified index position in the current node's child node list. |
| [Remove](../../aspose.cells.drawing.equations/equationnode/remove/)() | Removes itself from the parent. |
| [RemoveAllChildren](../../aspose.cells.drawing.equations/equationnode/removeallchildren/)() | Removes all the child nodes of the current node. |
| [RemoveChild](../../aspose.cells.drawing.equations/equationnode/removechild/#removechild)(EquationNode) | Removes the specified node from the current node's children. |
| [RemoveChild](../../aspose.cells.drawing.equations/equationnode/removechild/#removechild_1)(int) | Removes the node at the specified index from the current node's children. |
| [SetWordArtStyle](../../aspose.cells/fontsetting/setwordartstyle/)(PresetWordArtStyle) | Sets the preset WordArt style.(Inherited from [`FontSetting`](../../aspose.cells/fontsetting/).) |
| [ToLaTeX](../../aspose.cells.drawing.equations/equationnode/tolatex/)() | Convert this equtation to LaTeX expression. |
| [ToMathML](../../aspose.cells.drawing.equations/equationnode/tomathml/)() | Convert this equtation to MathML expression. |

using System;
using Aspose.Cells;
using Aspose.Cells.Drawing;
using Aspose.Cells.Drawing.Equations;

namespace AsposeCellsExamples
{
    public class EquationsClassEquationNodeDemo
    {
        public static void Run()
        {
            // Create a new workbook
            Workbook workbook = new Workbook();
            
            // Access the first worksheet
            Worksheet worksheet = workbook.Worksheets[0];
            
            // Add a text box to the worksheet and get its index
            int textBoxIndex = worksheet.TextBoxes.Add(10, 10, 200, 100);
            TextBox textBox = worksheet.TextBoxes[textBoxIndex];
            textBox.Text = "=A1+B1";
            
            // Get the equation node from the text box
            EquationNode node = textBox.GetEquationParagraph();
            
            // Output the equation text using ToString()
            Console.WriteLine("Equation: " + node.ToString());
            
            // Modify the equation by setting new text
            textBox.Text = "=A1*B1";
            Console.WriteLine("Modified Equation: " + textBox.Text);
        }
    }
