• Asp.Net 生成.xls文件 C#生成Excel文件下载


    前台导出Excel表格功能,主要是给查询时间和后台返回数据下载。

           $("#something").click(function () {
           var queryjson = {startTime:"",endTime:""};
    $.ajax({ url: "/test/testExcel/exportExcel?queryJson=" + JSON.stringify(queryJson), dataType: "json", type: "GET", success: function (data) {if (data.code == 1) { location.href = data.address;//前台的默认下载就要看这里 } else { alert("数据异常"); } } }); })

    下面主要是看后台了,后台主要是凭借html标签然后写入文件

    这里主要是展示一个表格的画法和循环带入,内容数据有改动,直接拷贝会对不上数据。

    这是一个Excel中多表格画法,只是增加多次表格内容。

            [HttpGet]
            public ActionResult exportExcel(string queryJson)
            {
              
                var jihe = GetReportCompanyTicketTypejson(queryJson).ToList();
                //如没有数据,返回前台提示无数据导出
                if (jihe.Count <= 0)
                {
                    return ToJsonResult(new { code = 3, address = "" });
                }//else nothing
                //获取统计数据
                var ZhiFulist = GetReportCompanyPayjson(queryJson).ToList();

                List<Entity.FoundManage.SS_TicketLevelEntity> createlogino = resList.Where(t => t.CreateLoginNo != null).ToList();
                string Cid = string.Empty, tdid = string.Empty;

                    #endregion
                }
                catch (Exception e)
                {
                    return Error("数据异常," + e.Message);
                    throw;
                }//创建表格
                var dizhi = WriteLog(html, "TestName");
                var result = new { code = 1, address = dizhi };
                return ToJsonResult(result);
            }

    是不是看头晕了,其实很简单,把前台的Html拿过来就好了

    现在  表格已经画好了,就差存储了,存储可以直接拿过去,比较简单啦

      public string WriteToExcle(string content, string singleMark)
            {
                string filename = singleMark + DateTime.Now.ToString("yyyy-MM-dd") + ".xls";
                //Get relative route of IIS
                string folder = System.Web.HttpContext.Current.Server.MapPath("~/excel");
                if (!Directory.Exists(folder))
                {
                    Directory.CreateDirectory(folder);
                }
                using (FileStream fs = new FileStream(folder + "/" + filename, System.IO.FileMode.Create, System.IO.FileAccess.Write))
                {
                    using (StreamWriter sw = new StreamWriter(fs, Encoding.UTF8))
                    {
                        sw.WriteLine(content + " ");
                        return "/excel/" + filename;
                    }
                }
            }

    存储相对简单很多,在服务器生成文件后吧地址返回给前台下载就可以了。

    结束、。。
