จะสร้างไดอะแกรมพื้นฐานด้วยโหนดเดียวในแอป C# ได้อย่างไร

// Create a GoView control
GoView myView = new GoView();

// Add it to your Windows Forms or WPF application

// Create a node
GoBasicNode myNode = new GoBasicNode();
myNode.Text = "My Node";

// Add the node to the view
myView.Document.Add(myNode);	

วิธีการแปลงไดอะแกรมเป็นรูปแบบรูปภาพโดยใช้ไลบรารี .NET

using System;
namespace GoDiagramToImage
{
    public partial class MainForm : Form
    {
        public MainForm()
        {
            InitializeComponent();
            InitializeGoDiagram();
        }

        private void InitializeGoDiagram()
        {
            // Create a GoView control and add it to the form
            GoView goView = new GoView();
            goView.Dock = DockStyle.Fill;
            Controls.Add(goView);

            // Load a sample diagram from a file (you can load your own diagram here)
            goView.Document.Clear();
            goView.Document.Add(new GoBasicNode() { Location = new PointF(100, 100), Text = "Sample Node 1" });
            goView.Document.Add(new GoBasicNode() { Location = new PointF(300, 100), Text = "Sample Node 2" });
            goView.Document.Add(new GoLink() { FromPort = goView.Document[0].BottomPort, ToPort = goView.Document[1].TopPort });

            // Optional: Perform an automatic layout to arrange the diagram nicely
            goView.Document.Layout = new GoLayoutForceDirected();
        }

        private void exportButton_Click(object sender, EventArgs e)
        {
            // Create a Bitmap to render the diagram
            Bitmap diagramImage = new Bitmap(goView.ClientSize.Width, goView.ClientSize.Height);
            Graphics graphics = Graphics.FromImage(diagramImage);

            // Render the diagram onto the Bitmap
            goView.DrawView(graphics);

            // Save the Bitmap as an image file (e.g., PNG)
            diagramImage.Save("Diagram.png", System.Drawing.Imaging.ImageFormat.Png);

            // Clean up resources
            graphics.Dispose();
            diagramImage.Dispose();
        }
    }
