asp.net用npoi读取ecxel数据到oracle表

1.html部分  

<div style="margin-bottom: 0px; margin-top: 5px; vertical-align: top;">
                    <span style="height: 30px; vertical-align: top;">上传文件：</span> <span id="uploadFile">
                        加载中...</span>
                </div>
           

2.javascript

<script type="text/javascript" language="javascript" src="<%= Page.ResolveUrl("~/Scripts/flash/fileupload.js") %>"></script>    
    <script type="text/javascript">
        $(function () {
            var params = {
                serverUrl: "/Pages/ZHCXPG/ImportAREAExcel.aspx?faid=" + parent.faid,
                jsFunction: "callBackFun",
                uploadText: "上传文件",
                filter: "*.xls;*.xlsx",
                maxFileCount: 1
            }
            initData(params, "uploadFile", 300);
        });
    </script>
           

3.后台代码

4.数据库表

create table Z_GBZ_AREA 
(
   ID                   NUMBER(8)            not null,
   XZQDM                VARCHAR2(38),
   XZQMCNAME            VARCHAR2(50),
   GJJBN                CHAR(1)              default '0',
   GBZJB                CHAR(1)              default '0',
   GJJPK                CHAR(1)              default '0',
   constraint PK_Z_GBZ_AREA primary key (ID)
);
