[c#] How to do a background for a label will be without color?

I want to add a label to my form , and I want it without any color- I want just it's text to be visible, I don't find this option in the label's properties, can anyone help me please?

If you picture box in the background then use this:

label1.Parent = pictureBox1;
label1.BackColor = Color.Transparent;

Put this code below InitializeComponent(); or in Form_Load Method.

This uses Graphics.CopyFromScreen so the control needs to be added when it's visable on screen.

public partial class TransparentLabelControl : Label
{
    public TransparentLabelControl()
    {
        this.AutoSize = true;
        this.Visible = false;

        this.ImageAlign = ContentAlignment.TopLeft;
        this.Visible = true;

        this.Resize += TransparentLabelControl_Resize;
        this.LocationChanged += TransparentLabelControl_LocationChanged;
        this.TextChanged += TransparentLabelControl_TextChanged;
        this.ParentChanged += TransparentLabelControl_ParentChanged;
    }

    #region Events
    private void TransparentLabelControl_ParentChanged(object sender, EventArgs e)
    {
        SetTransparent();
        if (this.Parent != null)
        {
            this.Parent.ControlAdded += Parent_ControlAdded;
            this.Parent.ControlRemoved += Parent_ControlRemoved;
        }
    }

    private void Parent_ControlRemoved(object sender, ControlEventArgs e)
    {
        SetTransparent();
    }

    private void Parent_ControlAdded(object sender, ControlEventArgs e)
    {
        if (this.Bounds.IntersectsWith(e.Control.Bounds))
        {
            SetTransparent();
        }
    }

    private void TransparentLabelControl_TextChanged(object sender, EventArgs e)
    {
        SetTransparent();
    }

    private void TransparentLabelControl_LocationChanged(object sender, EventArgs e)
    {

        SetTransparent();
    }

    private void TransparentLabelControl_Resize(object sender, EventArgs e)
    {
        SetTransparent();
    }
    #endregion

    public void SetTransparent()
    {
        if (this.Parent!= null)
        {
            this.Visible = false;
            this.Image = this.takeComponentScreenShot(this.Parent);
            this.Visible = true;                
        }
    }

    private  Bitmap takeComponentScreenShot(Control control)
    {
        Rectangle rect = control.RectangleToScreen(this.Bounds);
        if (rect.Width == 0 || rect.Height == 0)
        {
            return null;
        }
        Bitmap bmp = new Bitmap(rect.Width, rect.Height, PixelFormat.Format32bppArgb);
        Graphics g = Graphics.FromImage(bmp);

        g.CopyFromScreen(rect.Left, rect.Top, 0, 0, bmp.Size, CopyPixelOperation.SourceCopy);

        return bmp;
    }

}

Generally, labels and textboxes that appear in front of an image is best organized in a panel. When rendering, if labels need to be transparent to an image within the panel, you can switch to image as parent of labels in Form initiation like this:

var oldParent = panel1;
var newParent = pictureBox1;

foreach (var label in oldParent.Controls.OfType<Label>())
{
    label.Location = newParent.PointToClient(label.Parent.PointToScreen(label.Location));
    label.Parent = newParent;
    label.BackColor = Color.Transparent;
}

this.label1.BackColor = System.Drawing.Color.Transparent;

You are right. but here is the simplest way for making the back color of the label transparent In the properties window of that label select Web.. In Web select Transparent :)
