Just do something like this:

   var username = txtUserName.Text;
   var password = txtPassword.Text;// there is available encryption on the web that you can use on. and your code will be like var password=enc.EncryptToString(txtPassword.Text);
   var isValidUser = from user on UserTable
                     where user.UserName == txtUserName.Text && user.Password == password && user.Status == 1
                     select user;  
   if(isValiduser.Count() > 0)
   {
     //OK you can log on
   }
   else
   {
     //user credential is invalid
   }
