Get the size of an Image

I'm making a little Windows Forms app to select an image from your PC, and then display the image in pictureBox1 using the filepath.

private void button1_Click(object sender, EventArgs e)
{
    if (openFileDialog1.ShowDialog() == DialogResult.OK)
    {
        textBox1.Text = openFileDialog1.FileName;
        pictureBox1.ImageLocation = openFileDialog1.FileName;
    }
}

Now I want to put the dimensions (in pixels) of the image in an other textbox.

Is this possible the way I'm doing it?

Open the image using Image.FromFile method

Image image = Image.FromFile(openFileDialog1.FileName);

Put your image in the pictureBox1

pictureBox1.Image = image;

What you need is System.Drawing.Image class. The size of the image is in the image.Size property. But if you want to get Width and Height separately, you can use image.Width and image.Height respectively

Then in your other TextBox (suppose the name is textBox2) You can simply assign the Text property like this,

textBox2.Text = "Width: " + image.Width.ToString() + ", Height: " + image.Height.ToString();

Complete code:

private void button1_Click(object sender, EventArgs e)
{
    if (openFileDialog1.ShowDialog() == DialogResult.OK)
    {
        textBox1.Text = openFileDialog1.FileName;
        Image image = Image.FromFile(openFileDialog1.FileName);
        pictureBox1.Image = image; //simply put the image here!
        textBox2.Text = "Width: " + image.Width.ToString() + ", Height: " + image.Height.ToString();
    }
}

I don't think that you can get the size when setting the image using ImageLocation (As the PictureBox handles loading internally). Try loading the image using Image.FromFile, and using the Width and Height properties of that.

var image = Image.FromFile(openFileDialog1.FileName);
pictureBox1.Image = image;
// Now use image.Width and image.Height

Try this

System.Drawing.Image img = System.Drawing.Image.FromFile(openFileDialog1.FileName);
MessageBox.Show("Width: " + img.Width + ", Height: " + img.Height);
