下面的代码通过radLoginType.SelectedIndex来区分用户是个人或是企业，我现在想要跳过这一步，直接就去找个人表，和企业表，到个人表找到就去个人页面，在企业表里找到用户就去企业页面，要怎么改呢？

protected void imgLogin_Click(object sender, ImageClickEventArgs e)
{
if (radLoginType.SelectedIndex == 0)
{
//用户登陆
JHJob.Module.User user = null;
HttpCookie cok = null;
new UserAgent().UserLogin(this.txtLoginName.Text.Trim(),
JHJob.WebUtility.Security.Secure.Md5(this.txtLoginPwd.Text.Trim()),
Request.UserHostAddress, out user, out cok);
if (user != null)
{
cok.Expires = DateTime.Now.AddMinutes(20);
Response.SetCookie(cok);
this.loginName = user.LoginName;
this.message = "希望您能在这里找到更多适合您的职位！";
this.loginDate = user.LoginDate.ToShortDateString().Equals("1800-1-1") ? "您是第一次登陆" : user.LoginDate.ToShortDateString();
this.loginIp = user.LoginIp.Equals("") ? "无" : user.LoginIp;
this.backURL= "userManager/index.aspx";
this.pan_NoLogin.Visible = false;
this.pan_Logined.Visible = true;
}
else
{
WebUtility.ShowMessage(Page, "帐号或密码错误，登陆失败！");
}
