.net生成大量静态页面速度太慢，想使用多线程解决这个问题。但不会用。请大家帮忙！！！！现在1000多条新闻要三四分钟。
附上需要修改的代码：
protected void wznewxq_Click(object sender, EventArgs e)
{
string q1 = "select NS_Id from NewsSort where NS_Stop=0 order by NS_Order desc";
DataSet qq1 = DBHelper.GetDataSet(q1);
int a = 0;

{
string w1 = "select * from News,NewsSort where News.N_Sortid=NewsSort.NS_Id and N_Sortid=" + qq1.Tables[0].Rows[q]["NS_Id"] + " and N_Show=1 order by N_Order desc";
DataSet ww1 = DBHelper.GetDataSet(w1);
