Question

I have a problem saving images from PictureBox1 to my SQL server database, I\'ve done my research and found out that I have to convert my image to a byte array in order to d

Answer 1

You just need to define an image path named "imgpath"

//upload image

private void button1_Click_1(object sender, EventArgs e)
{
    OpenFileDialog opf = new OpenFileDialog();

    opf.Filter = "Choose Image(*.jpg; *.png; *.gif)|*.jpg; *.png; *.gif";
    if (opf.ShowDialog() == DialogResult.OK)
    {
        imgpath.Text = opf.FileName;
        pictureBox3.Image = Image.FromFile(opf.FileName);
    }
}
// ADD NEW/INSERT IMAGE TO DB
private void button5_Click(object sender, EventArgs e)
{
    string filepath = imgpath.Text;
    string filename = Path.GetFileName(imgpath.Text);
    FileStream fs = new FileStream(imgpath.Text, FileMode.Open, 
     FileAccess.Read);
    BinaryReader br = new BinaryReader(fs);
    Byte[] bytes = br.ReadBytes((Int32)fs.Length);
    br.Close();
    fs.Close();

    if (imgpath.Text != "")
    {
        cmd = new SqlCommand("insert into tbl_Record(@StudentImage)", con);
        con.Open();
        MemoryStream ms = new MemoryStream();

       // must use toolbox to add picturebox
        pictureBox3.Image.Save(ms, pictureBox3.Image.RawFormat);
        byte[] img = ms.ToArray();
        cmd.Parameters.Add("@StudentImage", SqlDbType.Binary).Value = 
       bytes;
        cmd.ExecuteNonQuery();
        con.Close();
        MessageBox.Show("Succeed");
        DisplayData();
        ClearData();
    }
    else
    {
        MessageBox.Show("Fill Required Informations!");
    }
}
