Is there a way to implement a flat TextBox in C #?

Question

I have a flat style GUI for buttons. I would like to use TextBox controls with the same appearance, but I cannot find where I can configure the external line. Is there any control in WinForms that can be assigned FlatStyle? Thanks!

Thanks for the FixedSingle border style information, but then, how can I change the line properties?

I implemented a solution with a small amount of both. I would like if you could help improve this class, since I am not an expert in C #, and I find this code somewhat dirty. Here is the code:

class BorderTextBox : UserControl
{
    private TextBox m_textBox;
    private int m_borderSize;

    private void ResizeComponent()
    {
        m_textBox.Size = new Size(Size.Width - 2 * m_borderSize, m_textBox.Size.Height);
        Size = new Size(Size.Width, m_textBox.Size.Height + 2 * m_borderSize);
    }

    protected override void OnResize(EventArgs z_event)
    {
        base.OnResize(z_event);
        ResizeComponent();
    }

    public BorderTextBox()
    {
        SuspendLayout();

        // TextBox
        m_textBox = new TextBox();
        m_textBox.BorderStyle = BorderStyle.None;
        m_textBox.Name = "textBox";
        m_textBox.TabIndex = 0;

        // Body
        BackColor = Color.Black;
        Name = "Body";
        Controls.Add(m_textBox);

        ResumeLayout(false);
        PerformLayout();
    }

    public bool UsePasswordStyle
    {
        get { return m_textBox.UseSystemPasswordChar; }
        set { m_textBox.UseSystemPasswordChar = value; }
    }

    public int BorderSize
    {
        get { return m_borderSize; }
        set
        {
            m_borderSize = value;
            m_textBox.Location = new Point(m_borderSize, m_borderSize);
            ResizeComponent();
        }
    }
}

ReadOnly. OnClick . OnClick :

class BorderTextBox : UserControl
{
    ...

    protected override void OnClick(EventArgs e)
    {
        if (!ReadOnly)
            base.OnClick(e);
    }        

    ...
}
