错误提示!!!

Question

string str="";
Response.Write("<table width='750' border='0' align='center' cellpadding='0' cellspacing='0'>");
                        Response.Write("<tr>");
                        for(int i=0;i<dt.Rows.Count;i++){
                            Response.Write("<tr>");
                            str=dt.Rows[i]["fpjmc"];  //这里出现错误,
                            Response.Write("<td>"+str);
                            Response.Write("<td>");
                            Response.Write("<tr>");
                        }如果把str改成str+,就没问题!!!!
