Question

I’m new to C# and I’m trying to open multiple images to an array to later manipulate their pixels, this is my code so far:

private void button1_Click(object sender, EventArgs e)
    {

        openFileDialog1.Filter = "Image Files(*.jpg; *.jpeg; *.bmp)|*.jpg; *.jpeg; *.bmp";
        if (openFileDialog1.ShowDialog() == DialogResult.OK)
        {
            Bitmap[] images = new Bitmap(openFileDialog1.FileNames);
            MessageBox.Show(images.Length+" images loaded","",MessageBoxButtons.OK);

        }
    }

I’m getting problems with this line

Bitmap[] images = new Bitmap(openFileDialog1.FileNames);

Can you help me?

Answer 1

Use:

 images = openFileDialog1.FileNames.Select(fn=>new Bitmap(fn)).ToArray();

Because openFileDialog1.FileNames is array of strings and Bitmap constructor expects single image file name
