  protected void Page_Load(object sender, EventArgs e)
  {

  }
  protected void Button1_Click(object sender, EventArgs e)
  {
  string bh = TextBox1.Text;
  string mm = TextBox2.Text;
  string hh = TextBox3.Text;
  string yx = youxiang.Text;
  string sex;
  string constr = "server=localhost;uid=sa;pwd=111111;database=bh";
  SqlConnection con = new SqlConnection(constr);

  if(RadioButtonList1.Items[0].Selected)
  sex=RadioButtonList1.Items[0].Value;
  else
  sex=RadioButtonList1.Items[1].Value;

  string cmdstr = "insert bh values('" + bh + "','" + mm + "','" + hh + "','" + yx + "','"+ sex +"')";
  SqlCommand cmd = new SqlCommand(cmdstr, con);
  con.Open();
  try
  {
  cmd.ExecuteNonQuery();
  }

  catch (Exception err) { Label1.Text = err.Message; }
  finally
  {
  con.Close();Response.Redirect("logion1.aspx");
  }
   
  }
}
为什么插不进数据库的表中，请高手指点，多谢多谢！！！！

string cmdstr = "insert into bh values('" + bh + "','" + mm + "','" + hh + "','" + yx + "','"+ sex +"')";

另外
if(RadioButtonList1.Items[0].Selected)
  sex=RadioButtonList1.Items[0].Value;
  else
  sex=RadioButtonList1.Items[1].Value;

其实只要
sex=RadioButtonList1.SelectedValue;
一句就行了。

掉了 into ，规范为：insert into tablename(各列明)values（各列对应的值）
设断点，将SQL语句放到数据库中执行，很快就能找到错误所在。
