asp.net获取flash里文本框的值

[hujunshengnet]

我有一个游戏flash点击提交时他有积分和所用时间我想把他插入到数据库中用asp.net编写了代码如 if (Request.QueryString["defen"] == null)
{

}
else
{
string userid = "";
int zongfen = int.Parse(Request.QueryString["defen"].ToString());
string tumu = "";
string sql = "insert into fenshu (userid,zongfen,time) values(userid,zongfen,time)";
SqlConnection cn = new SqlConnection("connectionString");
SqlCommand cmd = new SqlCommand(sql, cn);
cn.Open();
cmd.ExecuteNonQuery();
cn.Close();



}
flah里的代码
contactVars = new LoadVars();
contactVars.denfen= xuanzheti的.text;

contactVars.sendAndLoad('Default.aspx',contactVars,'post');
但是查不到数据库里请高手帮帮忙
