一个需求：将一个Excel文件中的数据导入到数据库中去。

思路：上传一个excel文件，读取该excel文件中数据，转成DataTable(或List)，循环insert到数据库中去

截图如下：

前端用到：jQuery-File-Upload-8.8.5    后台用到：Spire.Office.3.6.0

html代码:

@{
    ViewBag.Title = "djk8888";
}









用jQuery-File-Upload上传Excel文件(ASP.NET MVC)

上传

    

mvc代码：

using Spire.Xls;
using System.Collections.Generic;
using System.Data;
using System.IO;
using System.Web;
using System.Web.Mvc;

namespace workbook.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }
        /// 

        /// 上传excel文件
        /// 
        [HttpPost]
        public ActionResult UploadFiles()
        {
            bool b = false;
            var statuses = new List();
            var headers = Request.Headers;
            if (string.IsNullOrEmpty(headers["X-File-Name"]))
            {
                b = UploadWholeFile(Request, statuses);//上传文件
            }
            if (b)//上传成功
            {
                JsonResult result = Json(statuses);

            }
            var r = new List();
            return Json(r);//上传失败
        }
        private string StorageRoot
        {
            get { return Path.Combine(Server.MapPath("~/Files")); }//文件上传的路径：根目录下的/Files 文件夹
        }
        private bool UploadWholeFile(HttpRequestBase request, List statuses)
        {
            try
            {
                var file = request.Files[0];//文件源
                var fullPath = Path.Combine(StorageRoot, Path.GetFileName(file.FileName));//服务器文件完整路径
                file.SaveAs(fullPath);//复制文件

                Workbook workbook = new Workbook();
                workbook.LoadFromFile(fullPath);

                Worksheet worksheet = workbook.Worksheets[0];
                var dt = worksheet.ExportDataTable();

                //至此：已经获取上传的Excel文件中的内容并转成DataTable，即可进行写入(导入)数据库的操作(略)     
                Session["Upload"] = dt;//存到Session,用于展示上传的excel文件中的内容
