子栏目模型取值问题 [复制链接]

在子栏目模型中取容积流量的值， 容积流量是单选 1，xx  2,xx 3,xx 4,xx 5,xx 6,xx ,但通过后台给的参数只能取出前面的1 2 3 4 5 6来，不能取单选项后面的具体值，前面的123456改成具体值，系统又报错

子栏目模型是这样写的，
<script language="c#" runat="server">
private bool IsNum(string str)
{
  if(string.IsNullOrEmpty(str)){return false;}
  int rv=0;
  if(Int32.TryParse(str,out rv))
   {
    return true;  
   }
  else
   {
    return false;
   }
}
private string GetUrl(string sort,string hx,string fg,string mj,string designer)
{
   string url="/index.aspx?lanmuid=84&sublanmuid=826";
   if(IsNum(sort))
    {
      url+="&sort="+sort;
    }
   if(IsNum(hx))
    {
      url+="&hx="+hx;
    }
   if(IsNum(fg))
    {
      url+="&fg="+fg;
    }
   if(IsNum(mj))
    {
      url+="&mj="+mj;
    }
   if(IsNum(designer))
    {
      url+="&designer="+designer;
    }
  return url;
}
