采用这种方式，只需要新建一个页面做为辅助导入页面，实现的原理是将EXECL表上传到服务器，然后通过程序将EXECL表转化到AccessDatabase数据暂存，然后转化为DataTable数据，这样你就可以根据自己的要求存储数据；
首先，需要安装一个AccessDatabaseEngine.exe文件；
前端页面代码：
<div class="setting-page-dialog">
<table class="table table-config">
<tr>
<th>
<span class="required">*</span>导入文档：
</th>
<td>
<input type="file" class='action-item' runat="server" ID="txtFile"/>
</td>
</tr>
<tr>
<td colspan="2">
<span class="d_default"> 注意：文档格式：Excel，文档最大5M，最多500条会员数据。</a>
</td>
</tr>
</table>
</div>
<div class="footer-fixed">
<asp:Button ID="SaverButProductNotify" runat="server" Text="导入会员" class="btn" OnClick="LBtnUpProducts_Click" />
</div> 后端代码如下：
//上传按钮触发事件
protected void LBtnUpProducts_Click(object sender, EventArgs e)
{
//上传文件
string url = UpLoadXls(txtFile);
if (string.IsNullOrEmpty(url))
return;
//获取上传文件数据
var dtUsers= ImpExcelDt(url);
if (dtUsers != null)
{
//将数据添加到指定的数据库(这里根据自己实际需求来保存上传的数据)
AddUser(dtUsers);//代码（略）
}
}
/// <summary>
/// 上传Excel文件
/// </summary>
/// <param name="inputfile">上传的控件名</param>
/// <returns></returns>
private string UpLoadXls(System.Web.UI.HtmlControls.HtmlInputFile inputfile)
{
string orifilename = string.Empty;
string uploadfilepath = string.Empty;
string modifyfilename = string.Empty;
string fileExtend = "";//文件扩展名
int fileSize = 0;//文件大小
try
{
if (inputfile.Value != string.Empty)
{
//得到文件的大小
fileSize = inputfile.PostedFile.ContentLength;
if (fileSize == 0)
{
this.Page.ClientScript.RegisterStartupScript(this.GetType(), "ok", "<script type=\"text/javascript\">$(document).ready(function(){Ecshop.Tool.Hint.Error({info:'导入的Excel文件大小为0，请检查是否正确!'});});</script>");
return null;
//throw new Exception("导入的Excel文件大小为0，请检查是否正确！");
}
//获取文件的大小
if (fileSize > 1024*1024*5)
{
this.Page.ClientScript.RegisterStartupScript(this.GetType(), "ok", "<script type=\"text/javascript\">$(document).ready(function(){Ecshop.Tool.Hint.Error({info:'导入的Excel文件大小不能大于5M，请检查是否正确!'});});</script>");
return null;
}
//得到扩展名
fileExtend = inputfile.Value.Substring(inputfile.Value.LastIndexOf(".") + 1);
//if (inputfile.PostedFile.ContentType != "application/vnd.ms-excel")
if (!(fileExtend.ToLower() == "xls" || fileExtend.ToLower() == "xlsx"))
{
this.Page.ClientScript.RegisterStartupScript(this.GetType(), "ok", "<script type=\"text/javascript\">$(document).ready(function(){Ecshop.Tool.Hint.Error({info:'你选择的文件格式不正确，只能导入EXCEL文件!'});});</script>");
return null;
//throw new Exception("你选择的文件格式不正确，只能导入EXCEL文件！");
}
//路径
uploadfilepath = Server.MapPath("/uploads/upexcelusers");
//新文件名
modifyfilename = System.Guid.NewGuid().ToString();
modifyfilename += "." + inputfile.Value.Substring(inputfile.Value.LastIndexOf(".") + 1);
//判断是否有该目录
System.IO.DirectoryInfo dir = new System.IO.DirectoryInfo(uploadfilepath);
if (!dir.Exists)
{
dir.Create();
}
orifilename = uploadfilepath + "\\" + modifyfilename;
//如果存在,删除文件
if (File.Exists(orifilename))
{
File.Delete(orifilename);
}
// 上传文件(保存)
inputfile.PostedFile.SaveAs(orifilename);
}
else
{
this.Page.ClientScript.RegisterStartupScript(this.GetType(), "ok", "<script type=\"text/javascript\">$(document).ready(function(){Ecshop.Tool.Hint.Error({info:'请选择要导入的Excel文件!'});});</script>");
return null;
}
}
catch (Exception ex)
