前台代码是在.net core bootstrap集成框架上的（这是效果浏览地址：http://core.jucheap.com），首先是添加Nuget包，
<button id="btnExport" type="button" class="btn btn-info " onclick="exportModel()"><i class="fa fa-paste"></i> 导出Excel</button>
function exportModel() { //导出
var delDatas = JucheapGrid.GetDataTableDeleteData();
if (delDatas.Len > 0 && delDatas.Data.length > 0) {
if (confirm("确认要导出这" + delDatas.Len + "条数据？")) {
// delDatas.Data 传入的id值
window.location.href = "/***/***?id=" + delDatas.Data;
}
} else {
alert("请选择要导出的数据！");
}
}
下面就是控制器代码：
#region 导出Excel.xlsx文件
public IActionResult ExportText()
{
string sWebRootFolder = _hostingEnvironment.WebRootPath;
string sFileName = $"{DateTime.Now.ToString("yyyyMMddHHmmssfff")}.xlsx";
FileInfo file = new FileInfo(Path.Combine(sWebRootFolder, sFileName));
if (file.Exists)
{
file.Delete();
file = new FileInfo(Path.Combine(sWebRootFolder, sFileName));
}
using (ExcelPackage package = new ExcelPackage(file))
{
string str = Request.Query["id"];//获取传过来的id
String[] str1 = str.Split(",");
long[] ids = new long[str1.Length];
for (int i = 0; i < str1.Length; i++)
{
ids[i] = long.Parse(str1[i]);//装成long数组
}
//根据id在数据库获取集合
IList<FeedbackDto> collection = _usermanagementservice.GetExportAsync(ids);
// 添加worksheet
ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("意见反馈列表");
worksheet.Cells[1, 1].Value = "***";//这的*号表示的是导出后列的名称
worksheet.Cells[1, 2].Value = "***";
worksheet.Cells[1, 3].Value = "***";
worksheet.Cells[1, 4].Value = "*** ";
worksheet.Cells[1, 5].Value = "***";
worksheet.Cells[1, 6].Value = "***";
worksheet.Cells[1, 7].Value = "***";
worksheet.Cells[1, 8].Value = "***";
worksheet.Cells[1, 1].Style.Font.Bold = true;
worksheet.Cells[1, 2].Style.Font.Bold = true;
worksheet.Cells[1, 3].Style.Font.Bold = true;
worksheet.Cells[1, 4].Style.Font.Bold = true;
worksheet.Cells[1, 5].Style.Font.Bold = true;
worksheet.Cells[1, 6].Style.Font.Bold = true;
worksheet.Cells[1, 7].Style.Font.Bold = true;
worksheet.Cells[1, 8].Style.Font.Bold = true;
for (int i = 0; i < collection.Count; i++)
{
worksheet.Cells[2 + i, 1].Value = collection[i].*;//这的*是字段名
worksheet.Cells[2 + i, 2].Value = collection[i].*;
worksheet.Cells[2 + i, 3].Value = collection[i].*;
worksheet.Cells[2 + i, 4].Value = collection[i].*;
worksheet.Cells[2 + i, 5].Value = collection[i].*;
worksheet.Cells[2 + i, 6].Value = collection[i].*;
worksheet.Cells[2 + i, 7].Value = collection[i].CreateTime.ToString();//日期tostring一下，不然是乱的
worksheet.Cells[2 + i, 8].Value = collection[i].UpdateTime.ToString();
}
package.Save();
}
return File(sFileName, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", sFileName);
}
新手代码，大神勿喷，
