Label Image mode to stretch

Question

I wrote this code to add my Labels:

JArray a = JArray.Parse(temp);
Label[] labels = new Label[100];
foreach (JObject o in a.Children<JObject>())
{
    foreach (JProperty p in o.Properties())
    {
        string name = p.Name;
        string value = p.Value.ToString();
        if (name == "name")
        {
            labels[counter] = new Label();
            //Image i = Image.FromFile("item.jpg");
            labels[counter].Text = value;
            labels[counter].Image =Image.FromFile("item.jpg");
            //labels[counter].Image
            //labels[counter].BackColor = Color.Blue;
            labels[counter].TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
            labels[counter].Top = height;      
            height += 50;
            Controls.Add(labels[counter]);
        }
    }
}

The Image should stretch to the Label Size. How can I do this?

The abilities to show and manipulate images and text are spread out in a rather wild fashion among Winforms controls.

A Label can not stretch its Image.
A PictureBox and a Panel can but they don't show their Text
A Button can do both but will always be a Button, no matter how you style it..

So to get a combination you will need to either owner-draw something:

DrawImage in an overload to get the right size of the image, then add Image to Label
Or DrawString the Text onto a Panel to show it alongside the Image

or you could combine two controls with the right abilities:

You can create a Panel and set its BackgroundImage to your Image and its BackgroundImageLayout=Stretch. Then you can add your Label with its Text set to the Panel's controls collection:

// preparation for testing:
Image image = Image.FromFile("D:\\stop32.png");
Size size = new Size(77, 77);

// create the combined control
// I assume your Label is already there
Panel pan = new Panel();
pan.Size = size;
// or, since the Label has the right size:
pan.Size = label.Size;  // use Clientsize, if borders are involved!
pan.BackgroundImage = image;
pan.BackgroundImageLayout = ImageLayout.Stretch;
label.Parent = pan;  // add the Label to the Panel
label.Location = Point.Empty;
label.Text = "TEXT";
label.BackColor = Color.Transparent;

// add to (e.g.) the form
pan.Parent = this;

Set Borders as you like..

One more option: If all Images should have the same Size and if it is 256x256 pixels or less you could add them to an ImageList. This will stretch them to the ImageList.ImageSize in a very simple way and you can add them to your Label..

Very simple:

VB

Label1.Image = New Bitmap(Image.FromFile("Screenshot.jpg"), Label1.Size)

C#

Label1.Image = new Bitmap(Image.FromFile("Screenshot.jpg"), Label1.Size);

If you are using WinForms you try try below:

labels[counter].Size = 
    new Size(labels[counter].Image.Width, labels[counter].Image.Height);

how can i resize image? – elnaz irani May 01 '15 at 14:22
Bitmap ResizeBmp(Image.FromFile("item.jpg"), labels[counter].Width, labels[counter].Height ) { Bitmap result = new Bitmap(width, height); using (Graphics g = Graphics.FromImage(result)) g.DrawImage(sourceBMP, 0, 0, width, height); return result; } – Jack May 01 '15 at 14:31

This works perfect for me:

Just set the image in design mode (don't use imagelist) use the "Image" option
if we have label1 as the label where we want the image, put the next line inside the constructor:

label1.Image = new Bitmap(label1.Image, label1.Size);

I was trying the solution of Zibri, but deform the image in my case.
