Answer 1

SqlConnection con = new SqlConnection();
string _path;
Using SYstem.IO;
Using System.Data.SQLClient;

//convert Image to binary and save in DB

private void button1_Click(object sender, EventArgs e)
{
    if (openFileDialog1.ShowDialog() == DialogResult.OK)
    {
        _path = openFileDialog1.FileName;
        InsertInSQL(_path);
    }
}

private void InsertInSQL(string _path)
{
    con.ConnectionString = Pic.Properties.Settings.Default.ConnectionS;
    string strQ = "insert into dbo.PicTBL(Pic)values(@p)";
    SqlCommand command = new SqlCommand(strQ,con);
    command.Parameters.AddWithValue("@p",ImageToBinary(_path));
    con.Open();
    command.ExecuteNonQuery();
    con.Close();
}      

public static byte[] ImageToBinary(string _path)
{
    FileStream fS = new FileStream(_path, FileMode.Open, FileAccess.Read);
    byte[] b = new byte[fS.Length];
    fS.Read(b, 0, (int)fS.Length);
    fS.Close();
    return b;
}

//Convert Binary to imge and save in a folder
private void button1_Click_1(object sender, EventArgs e)
{
    DataTable dt = Rimage();
    foreach (DataRow row in dt.Rows)
    {
        byte[] b = (byte[])row["Pic"];
        Image img = BinaryToImage(b);
        img.Save("D:\\NewFolder\\" + row["ID"].ToString() + ".jpg");
    }
}

private Image BinaryToImage(byte[] b)
{
    if (b == null) 
        return null;

    MemoryStream memStream = new MemoryStream();
    memStream.Write(b, 0, b.Length);

    return Image.FromStream(memStream);
}

private DataTable Rimage()
{
    con.ConnectionString = Pic.Properties.Settings.Default.ConnectionS;
    SqlCommand cmd = new SqlCommand();
    cmd.CommandText = "select * from dbo.PicTBL";
    cmd.Connection = con;
    SqlDataAdapter adp = new SqlDataAdapter(cmd);
    DataTable dt = new DataTable();
    con.Open();
    adp.Fill(dt);

    return dt;
}
