public class Device : IDisposable

A device performs primitive-based rendering, creates resources, handles system-level variables, and gets and sets palettes.

The following code example creates a device.

public class CreateDevice : Form
    // Set global variables for this project.
    Device device = null;

    public CreateDevice()
        // Set the initial size of the form.
        this.ClientSize = new System.Drawing.Size(400, 300);
        // Set the caption for the form.
        this.Text = "D3D Tutorial 01: CreateDevice";

    public bool InitializeGraphics()
            // Set up presentation parameters and create the 
            // Direct3D device.
            PresentParameters presentParams = new PresentParameters();
            presentParams.Windowed = true;
            presentParams.SwapEffect = SwapEffect.Discard;
            device = new Device(0, DeviceType.Default, this, CreateFlags.None, presentParams);
            return true;
        catch (DirectXException)
            return false;
    private void Render()
        if (device == null)

        //Clear the backbuffer to a blue color. 
        device.Clear(ClearFlags.Target, System.Drawing.Color.Blue, 1.0f, 0);
        //Begin the scene.

        // Rendering scene objects, if desired.

        //End the scene.
    protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
        // Render on painting.
    protected override void OnKeyPress(System.Windows.Forms.KeyPressEventArgs e)
        if ((int)(byte)e.KeyChar == (int)System.Windows.Forms.Keys.Escape)
            // Handle the ESC key being pressed.

    /// <Summary>
    /// The main entry point for the application.
    /// </Summary>
    static void Main()

        using (CreateDevice DeviceForm = new CreateDevice())
            // Initialize Direct3D.
            if (!DeviceForm.InitializeGraphics())
                MessageBox.Show("Could not initialize Direct3D.  This tutorial will exit.");

            // While the form is still valid, render and process messages.
            // while (DeviceForm.Created)
