50分！类的问题！请高手进来看看解决就给分！顶者有分不够加分！
public   class   aa
{
public   string   c1;
public   string   c2;
public   string   c3;
public   string   c4;
public   string   c5;
public   string   c6;
}
public   static   bool   haha()
{
string   PriceID   =   String.Empty;
SqlConnection   con   =   showclass.datacon.AutoCon();
con.Open();
SqlCommand   cmd   =   new   SqlCommand( "cc_cc   "   +   PriceID,con);
aa   PV=new   aa();
using(SqlDataReader   sdr   =   cmd.ExecuteReader(CommandBehavior.CloseConnection))
{
if(sdr.Read())
{
PV.c1   =   sdr[ "auto_price "].ToString();
PV.c2   =   sdr[ "auto_color "].ToString();
PV.c3   =   sdr[ "user_dw "].ToString();
PV.c4   =   sdr[ "user_tel "].ToString();
PV.c5   =   sdr[ "AutoBrand "].ToString();
PV.c6   =   sdr[ "AutoType "].ToString();
}
}
con.Close();
}
这个类那里写的不对！
然后在别的页面如何调用?
