This works for me:

public void updatedatabase()
{

    SqlConnection conn = new SqlConnection("Data Source=" + txtserver.Text.Trim() + ";Initial Catalog=" + txtdatabase.Text.Trim() + ";User ID=" + txtuserid.Text.Trim() + ";Password=" + txtpwd.Text.Trim() + "");
    try
    {

        conn.Open();

        string script = File.ReadAllText(Server.MapPath("~/Script/DatingDemo.sql"));

        // split script on GO command
        IEnumerable commandStrings = Regex.Split(script, @"^\s*GO\s*$", RegexOptions.Multiline | RegexOptions.IgnoreCase);
        foreach (string commandString in commandStrings)
        {
            if (commandString.Trim() != "")
            {
                new SqlCommand(commandString, conn).ExecuteNonQuery();
            }
        }
        lblmsg.Text = "Database updated successfully.";

    }
    catch (SqlException er)
    {
        lblmsg.Text = er.Message;
        lblmsg.ForeColor = Color.Red;
    }
    finally
    {
        conn.Close();
    }
}
