解决方案二：
namespace WebApplication9
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender EventArgs e)
{
}

    protected void dr_Click(object sender EventArgs e)    {        string conn = ""Data Source= orc;User ID=xuehp;Password=xue920919"";     OracleConnection cn = new OracleConnection(conn);    cn.Open();    string strsql = ""select count(*) from chicken where name='"" + username.Text + ""' and password='"" + userpassword.Text + ""'"";    OracleCommand cmd = new OracleCommand(strsql cn);   OracleDataReader rd = cmd.ExecuteReader();    if (rd.Read())    {        if (rd.GetValue(0).ToString() == username.Text)        {            if (rd.GetValue(1).ToString() ==userpassword.Text)            {                Response.Redirect(""Default.aspx"");            }            else            {                Response.Write(""<script>alert('密码错误！')</script>"");            }        }        else        {            Response.Write(""<script>alert('用户名错误！')</script>"");        }    }    else    {        Response.Write(""<script>alert('用户不存在！')</script>"");    }}    }}
