数据导出总结

1.首先引用ExcelLib.cs这个文件。

2.插入如下代码：

DataTable dt = GetTable(resu);

                ExcelLib excHelper = new ExcelLib();

                //write content

                excHelper.WriteCells(dt, 0, 0, true);

                //set style,optional

                excHelper.SetHeaderRowStyle(0, 0, dt.Columns.Count);

                excHelper.SetAltRowStyle(0, 0, dt, true);

                excHelper.SetColumnsWidth(0, dt.Columns.Count, 30);



                string fileName = string.Format("{0}-{1}.xls", Lincoln3R.Resources.Resource.lbl_Report, Lincoln3R.Resources.Resource.Submenu_Report2);

                byte[] buffer = excHelper.GetMemoryStream();

                TransmitFile(fileName, buffer);

3.GetTable方法：举例说明，就是生成一个DataTable。

private DataTable GetTable(IList<TVehicle> countResult)

        {

            //re-do this job, so that the header is in right language.

            columnHead = new string[16]{

                Lincoln3R.Resources.Resource.Lbl_VIN,    

                Lincoln3R.Resources.Resource.Lbl_Last3RServiceDealerCode,

                Lincoln3R.Resources.Resource.Lbl_Last3rServiceAdvisorNo,    

                Lincoln3R.Resources.Resource.Lbl_SegmentNo,

                Lincoln3R.Resources.Resource.Lbl_SegmentDescription,    

                Lincoln3R.Resources.Resource.Lbl_ModelNo,    

                Lincoln3R.Resources.Resource.Lbl_ModelDescription,    

                Lincoln3R.Resources.Resource.Lbl_LicenseNo,    

                Lincoln3R.Resources.Resource.Lbl_InitRegDate,    

                Lincoln3R.Resources.Resource.Lbl_Mileage,    

                Lincoln3R.Resources.Resource.Lbl_lastwarrentyrepairdate,    

                Lincoln3R.Resources.Resource.Lbl_Last3Rstatusupdatedate,    

                Lincoln3R.Resources.Resource.Lbl_TotalWarrantyRepairs,    

                Lincoln3R.Resources.Resource.Lbl_AccumulativeRepairDays,    

                Lincoln3R.Resources.Resource.Lbl_3RRepairs,    

                Lincoln3R.Resources.Resource.Lbl_3RStatus

            };



            DataTable dt = new DataTable();

            //this part of code is generated by excel

            dt.Columns.Add(new DataColumn(columnHead[0]));

            dt.Columns.Add(new DataColumn(columnHead[1]));

            dt.Columns.Add(new DataColumn(columnHead[2]));

            dt.Columns.Add(new DataColumn(columnHead[3]));

            dt.Columns.Add(new DataColumn(columnHead[4]));

            dt.Columns.Add(new DataColumn(columnHead[5]));

            dt.Columns.Add(new DataColumn(columnHead[6]));

            dt.Columns.Add(new DataColumn(columnHead[7]));

            dt.Columns.Add(new DataColumn(columnHead[8]));

            dt.Columns.Add(new DataColumn(columnHead[9]));

            dt.Columns.Add(new DataColumn(columnHead[10]));

            dt.Columns.Add(new DataColumn(columnHead[11]));

            dt.Columns.Add(new DataColumn(columnHead[12]));

            dt.Columns.Add(new DataColumn(columnHead[13]));

            dt.Columns.Add(new DataColumn(columnHead[14]));

            dt.Columns.Add(new DataColumn(columnHead[15]));



            for (int i = 0; i < countResult.Count; i++)

            {

                

                DataRow dr = dt.NewRow();

                dr[0] = countResult[i].Vin;

                dr[1] = countResult[i].Last3rRepairDealerCode;

                dr[2] = (string.IsNullOrWhiteSpace(countResult[i].Last3rsaNo) && string.IsNullOrWhiteSpace(countResult[i].Last3rsaName))?

                    "":string.Format("{0}-{1}",countResult[i].Last3rsaNo,countResult[i].Last3rsaName);

                dr[3] = countResult[i].SegmentNo;

                dr[4] = countResult[i].SegmentDescription;

                dr[5] = countResult[i].ModelNo;

                dr[6] = countResult[i].ModelDescription;

                dr[7] = countResult[i].LicenseNo;

                if (countResult[i].InitialRegistrationDate.HasValue) dr[8] = countResult[i].InitialRegistrationDate.Value.ToString("yyyy-MM-dd HH:mm:ss");

                dr[9] = countResult[i].Mileage.ToString("F0");

                if (countResult[i].LastWarrantyRepairDate.HasValue) dr[10] = countResult[i].LastWarrantyRepairDate.Value.ToString("yyyy-MM-dd HH:mm:ss");

                if (countResult[i].Last3rRepairStatusUpdateDate.HasValue) dr[11] = countResult[i].Last3rRepairStatusUpdateDate.Value.ToString("yyyy-MM-dd HH:mm:ss");

                dr[12] = countResult[i].TotalWarrantyRepairTimes;

                dr[13] = countResult[i].AccumulativeRepairDays;

                dr[14] = countResult[i].Total3rRepairTimes;

                switch( countResult[i].ThreerStatus)

                {

                    case "R":

                        dr[15] = Lincoln3R.Resources.Resource.Tip_Red;

                        break;

                    case "Y":

                        dr[15] = Lincoln3R.Resources.Resource.Tip_Yellow;

                        break;

                    case "O":

                        dr[15] = Lincoln3R.Resources.Resource.Tip_Orange;

                        break;

                }

                dt.Rows.Add(dr);

            }



            return dt;

        }

4.TransmitFile方法是将数据输出。

private void TransmitFile(string fileName, byte[] buffer)

        {

            Response.ContentType = "application/octet-stream;charset=UTF-8";

            if (true)//UserSession.CurrentUser.CurrentCulture == Lincoln3R.Framework.I18N.CultureHelper.I18N_ZH_CN)

            {

                fileName = HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8);

            }

            Response.AddHeader("Content-Disposition", "attachment;  filename=" + fileName);

            Response.BinaryWrite(buffer);

            Response.Flush();

            HttpContext.Current.ApplicationInstance.CompleteRequest();

        }
