                             {      
                                             Ads.UpdateCommand    =    "update    Sysconfig(pageSize)    values(@pageSize)";

                                             Ads.Update();      
                             }      
   
页面代码：

             {      
                             SC.PageSize    =    Convert.ToInt32(txtPagesize.Text);      
                             op.UpdateBookSet(SC);

提问：我的sc类设置绝对没有问题！！

public    void    UpdateBookSet(SysConfig    SC)      
                             {      
                                             Ads.UpdateCommand    =    "update    Sysconfig(pageSize)    values(@pageSize)";      
                                             Ads.UpdateParameters.Add(new    Parameter("@pageSize",TypeCode.Int32,SC.PageSize.ToString()));  //加@号和SC.PageSize.ToString()    
                                             Ads.Update();      
                             }
