c# - Loading PictureBox Image From Database

i'm trying to load images from database to a PictureBox. I use these following codes in order to load them to my picture. I've written some code but don't know what I should do for continuing.

Any help will be appreciated.

private void button1_Click(object sender, EventArgs e)
    {
        sql = new SqlConnection(@"Data Source=PC-PCPC;Initial Catalog=Test;Integrated Security=True");
        cmd = new SqlCommand();
        cmd.Connection = sql;
        cmd.CommandText = ("select Image from Entry where EntryID =@EntryID");
        cmd.Parameters.AddWithValue("@EntryID", Convert.ToInt32(textBox1.Text));
    }

Continue with something like this in the button1_Click:

// Your code first, here.

var da = new SqlDataAdapter(cmd);
var ds = new DataSet();
da.Fill(ds, "Images");
int count = ds.Tables["Images"].Rows.Count;

if (count > 0)
{ 
    var data = (Byte[])ds.Tables["Images"].Rows[count - 1]["Image"];
    var stream = new MemoryStream(data);
    pictureBox1.Image = Image.FromStream(stream);
}
