求助..简单问题 先谢谢各位

Question

  if (????)
        {
            
            int ID = Convert.ToInt32(Request.QueryString["ID"]);
            string MarkIP = Request.QueryString["MarkIP"];
            string re = txt_Memo.Text;            cl.UpdateRe(MarkIP, ID, re);
            Page.RegisterStartupScript("alert", "<script>alert('保存成功!');</script>");
            return;
        }
这是我后台页面已经写好的  public bool UpdateRe(string MarkIP, int ID, string re)
        {
            return ((ICallLog)dal).UpdateRe(MarkIP, ID,re);
        }这个是后台UpdateRe的方法
public bool UpdateRe(string MarkIP, int ID, string re)
        {
            DALSqlEngine dal = new HC.Purview.DAO.DALSqlEngine(_loginid);
            try
            {
                DALSqlParameter[] cmdParam = (DALSqlParameter[])dal.GetCachedParameters(SP_UpdateRe);
                if (cmdParam == null)
                {
                    cmdParam = new DALSqlParameter[] { 
                                                    new DALSqlParameter(p_ID,SqlDbType.Int),
                                                    new DALSqlParameter(p_MarkIP,SqlDbType.VarChar,20),
                                                    new DALSqlParameter(p_re,SqlDbType.VarChar,100),
                    };
                    dal.CacheParameters(SP_UpdateRe, cmdParam);
                }
                cmdParam[0].Value = ID;
                cmdParam[1].Value = MarkIP;
                cmdParam[2].Value = re;
                int a = dal.Exec_NonQuery(CommandType.StoredProcedure, SP_UpdateRe, cmdParam);
                if (a > 0)
                {
                    return true;
                }
                else
                    return false;
            }
｝

if (????)
  {
    
  int ID = Convert.ToInt32(Request.QueryString["ID"]);
  string MarkIP = Request.QueryString["MarkIP"];
  string re = txt_Memo.Text;  cl.UpdateRe(MarkIP, ID, re);
  Page.RegisterStartupScript("alert", "<script>alert('保存成功!');</script>");
  return;
  }
这是我后台页面已经写好按钮的方法

Answer 2

public bool UpdateRe(）这个方法不是有返回值么
if (a > 0)
  {
  return true;
  }
  else
  return false;
  }

Answer 3

bool ai =  cl.UpdateRe(MarkIP, ID, re);
if(bool)
{
Page.RegisterStartupScript("alert", "<script>alert('保存成功!');</script>");
}
else
{
//失败
}

Answer 4

    
  int ID = Convert.ToInt32(Request.QueryString["ID"]);
  string MarkIP = Request.QueryString["MarkIP"];
  string re = txt_Memo.Text; if(cl.UpdateRe(MarkIP, ID, re))
  Page.RegisterStartupScript("alert", "<script>alert('保存成功!');</script>");
 else
  return;
