毕业了，想做个网站用来放一些同学的资料，做了个登陆控件，却不能达到预期效果，自己也找不出什么毛病，还望有人告诉我啊。

Web控件：  
  protected System.Web.UI.WebControls.RadioButtonList rbtLoginChk;  
  protected System.Web.UI.WebControls.TextBox txtLoginPwd;  
  protected System.Web.UI.WebControls.LinkButton lbtnLostPwd;  
  protected System.Web.UI.WebControls.TextBox txtLoginUser;  
  protected System.Web.UI.WebControls.Button btnLoginIn;  
  
  
编写的代码：  
  private void btnLoginIn\_Click(object sender, System.EventArgs e)  
  \{  
   string LoginUser = this.txtLoginUser.Text.ToString(); //获取登陆用户  
   string LoginPwd = this.txtLoginPwd.Text.ToString();  //获取登陆密码  
   int Result; //定义Result字符串用于把cmd.ExecuteScalar转化为Int类型

SqlConnection con = new SqlConnection("server=.;database=txl;uid=sa;pwd=sa;");  
   con.Open();  
   if(this.rbtLoginChk.SelectedItem.Text == "姓名") //以姓名方式登陆  
   \{  
    SqlCommand cmd = new SqlCommand("select personName,personPwd from beadroll where personName = '"+LoginUser+"' and personPwd = '"+LoginPwd +"'",con); //根据输入的数据从数据库中检索姓名、密码登陆  
    Result = Convert.ToInt32(cmd.ExecuteScalar());  
   \}  
   else //以学号方式登陆  
   \{  
    SqlCommand cmd = new SqlCommand("select personID,personPwd from beadroll where personID = '"+LoginUser+"' and personPwd = '"+LoginPwd+"'",con); //根据输入数据从数据库中检索学号、密码登陆  
    Result = Convert.ToInt32(cmd.ExecuteScalar());  
   \}  
     
   if(Result>0) //有返回值  
   \{  
    Response.Redirect("correct.aspx");  
   \}  
   else //返回值为空  
   \{  
    Response.Redirect("false.aspx");  
   \}  
  \}
