Do you want to make the label (except for the text) transparent? Windows Forms (I assume WinForms - is this true) doesn't really support transparency. The easiest way, sometimes, is Label's Backcolor to Transparent. 

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

You will run into problems though, as WinForms really doesn't properly support transparency. Otherwise, see here:

Setting the parent of a usercontrol prevents it from being transparent

Good luck!

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.

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 :)

Solution 4:[4]

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

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 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;
    }

}

An easy way to have a label with a picture behind it is to use the Image Property of the label itself. This will print the text over the top of the picture, and enable you to align the image (top/bottom/left/right/centre) as required.picture

Let's view 2 possible cases.

  1. Background is a color. Double-Click the form background in VS constructor. Then, write this code:
/*
This code will set all your object's background color to the same as the form.
This should be written in the body of <FormName>_Load(object, EventArgs).
*/
Control[] objs = new Control[] { /* your object list, e. g { myLabel, myPicture } */ };
foreach (Control control in objs) {
  control.BackColor = Color.Transparent;
  // OR
  control.BackColor = this.BackColor;
}
  1. Background is a PictureBox. This is also easy. We just need to make all objects as children of your PictureBox and set it's color to transparent. Code:
/*
This code will set all your object's background to transparent and show the PBox.
This should be written in the body of <FormName>_Load(object, EventArgs)'s foreach loop.
Put everything before it the same as in 1st code fragment.
*/
control.Parent = back;
control.BackColor = Color.Transparent;

Let's see the pictures.
