How to do a background for a label will be without color?

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

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!

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 :)

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.
