@插入操作【我這里用到的是存儲過程】
c# 代碼
??????????????????????????public?string?InsertTB_Article(int?AttributeID,?string?Links,?int?TeamBuyInfoID,?string?Title,?string?Content,?string?MemberName,?int?MemberID) ??{ ??????IDataParameter[]?p?=?new?IDataParameter[7]; ??????p[0]?=?new?SqlParameter("AttributeID",?AttributeID); ??????p[1]?=?new?SqlParameter("Links",?Links); ??????p[2]?=?new?SqlParameter("TeamBuyInfoID",?TeamBuyInfoID); ??????p[3]?=?new?SqlParameter("Title",?Title); ??????p[4]?=?new?SqlParameter("Content",?Content); ??????p[5]?=?new?SqlParameter("MemberName",?MemberName); ??????p[6]?=?new?SqlParameter("MemberID",?MemberID); ??????????return?DbHelperSQL.RunProcedureState("Proc_Add_TB_Article",?p); ??} ?? 另外我里面有3個分頁程序，2個是需要用到存儲過程，另一個是由ACCESS演化而來，效率上不比存儲過程差
