ASP.NET利用MD.DLL转EXCEL具体实现
网络编程 2021-07-04 22:40www.168986.cn编程入门
引入MD.dll 文件(附有下载地址)然后建立无CS文件的DownExcel.aspx 文件，接下来是调用方法，感兴趣的朋友可以参考下哈
前提
引入MD.dll 文件；

1、建立无CS文件的DownExcel.aspx 文件

2、调用方法
http://localhost:13042/report/downexcel.aspx?procedure=P_PP_SPC_FindCount&strWorkCenterNum=0&strStatus=全部&strPartno=
注解
P_PP_SPC_FindCoun:存储过程
WorkcenterNum:参数
在每个参数前都要加上‘Str'表示该参数是字符串型
所以参数要写成StrWorkcenterNum
