public ActionResult ExportToExcel() { var package = new ExcelPackage(); var worksheet = package.Workbook.Worksheets.Add("Sheet1"); //表格边框 worksheet.Cells[1,1,3,3].Style.Border.Left.Style = ExcelBorderStyle.Thin; worksheet.Cells[1, 1, 3, 3].Style.Border.Right.Style = ExcelBorderStyle.Thin; worksheet.Cells[1, 1, 3, 3].Style.Border.Top.Style = ExcelBorderStyle.Thin; worksheet.Cells[1, 1, 3, 3].Style.Border.Bottom.Style = ExcelBorderStyle.Thin; //表格居中 worksheet.Cells[1, 1, 3, 3].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center; //表格字体颜色 worksheet.Cells[1, 1].Style.Font.Color.SetColor(Color.Red); //设置单元格背景色 worksheet.Cells[1, 1].Style.Fill.PatternType = ExcelFillStyle.Solid; worksheet.Cells[1, 1].Style.Fill.BackgroundColor.SetColor(Color.FromArgb(128, 128, 128)); // 添加表头 worksheet.Cells[1, 1].Value = "姓名"; worksheet.Cells[1, 2].Value = "年龄"; worksheet.Cells[1, 3].Value = "性别"; // 添加数据 worksheet.Cells[2, 1].Value = "张三"; worksheet.Cells[2, 2].Value = 25; worksheet.Cells[2, 3].Value = "男"; worksheet.Cells[3, 1].Value = "李四"; worksheet.Cells[3, 2].Value = 30; worksheet.Cells[3, 3].Value = "女"; // 自适应列宽 //worksheet.Cells.AutoFitColumns(); // 设置文件名 string fileName = "Export.xlsx"; // 将 Excel 文件转换为字节数组 byte[] fileContents = package.GetAsByteArray(); // 返回文件 return File(fileContents, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", fileName); }在里面添加个图表

可以在以下代码中添加图表：

// 添加图表
var chart = worksheet.Drawings.AddChart("Chart1", eChartType.ColumnClustered);
chart.SetPosition(4, 0, 6, 0);
chart.SetSize(600, 400);
var series = chart.Series.Add(worksheet.Cells["B2:B3"], worksheet.Cells["A2:A3"]);
chart.Title.Text = "年龄统计";
chart.Style = eChartStyle.Style2;

这段代码会在表格下方添加一个柱状图，用于展示年龄统计信息。你可以根据需要修改图表的类型、位置、大小、数据源等属性。

public ActionResult ExportToExcel() { var package = new ExcelPackage();//是一个epplus中的类 var worksheet = package.Workbook.Worksheets.Add("Sheet1");//Workbook 是 Excel 工作簿，Worksheets 是工作簿中的工作表集合 // 添加表头 cell代表表格或单元格 worksheet.Cells[1, 1].Value = "姓名"; worksheet.Cells[1, 2].Value = "年龄"; worksheet.Cells[1, 3].Value = "性别"; // 添加数据 worksheet.Cells[2, 1].Value = "张三"; worksheet.Cells[2, 2].Value = 20; worksheet.Cells[2, 3].Value = "男"; worksheet.Cells[3, 1].Value = "李四"; worksheet.Cells[3, 2].Value = 25; worksheet.Cells[3, 3].Value = "女"; // 自适应列宽 worksheet.Cells.AutoFitColumns(); // 导出 Excel 文件 var fileStream = new MemoryStream(package.GetAsByteArray()); var fileName = "export.xlsx"; var contentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; return View(new FileViewModel { FileStream = fileStream, ContentType = contentType, FileName = fileName }); }@model该怎么写

您可以这样写：

public class FileViewModel
{
public MemoryStream FileStream { get; set; }
public string ContentType { get; set; }
public string FileName { get; set; }
}

public ActionResult ExportToExcel()
{
var package = new ExcelPackage();
var worksheet = package.Workbook.Worksheets.Add("Sheet1");

worksheet.Cells[1, 1].Value = "姓名";
worksheet.Cells[1, 2].Value = "年龄";
worksheet.Cells[1, 3].Value = "性别";

worksheet.Cells[2, 1].Value = "张三";
worksheet.Cells[2, 2].Value = 20;
worksheet.Cells[2, 3].Value = "男";

worksheet.Cells[3, 1].Value = "李四";
worksheet.Cells[3, 2].Value = 25;
worksheet.Cells[3, 3].Value = "女";

worksheet.Cells.AutoFitColumns();

var fileStream = new MemoryStream(package.GetAsByteArray());
var fileName = "export.xlsx";
var contentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";

return View(new FileViewModel { FileStream = fileStream, ContentType = contentType, FileName = fileName });
}

public ActionResult ExportToExcel() { var package = new ExcelPackage(); var worksheet = package.Workbook.Worksheets.Add("Sheet1"); // 添加表头 worksheet.Cells[1, 1].Value = "姓名"; worksheet.Cells[1, 2].Value = "年龄"; worksheet.Cells[1, 3].Value = "性别"; // 添加数据 worksheet.Cells[2, 1].Value = "张三"; worksheet.Cells[2, 2].Value = 20; worksheet.Cells[2, 3].Value = "男"; worksheet.Cells[3, 1].Value = "李四"; worksheet.Cells[3, 2].Value = 25; worksheet.Cells[3, 3].Value = "女"; // 自适应列宽 worksheet.Cells.AutoFitColumns(); // 导出 Excel 文件 var fileStream = new MemoryStream(package.GetAsByteArray()); var fileName = "export.xlsx"; var contentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; return File(fileStream, contentType, fileName); }接下来该如何操作

这是一个 ASP.NET MVC 控制器中导出 Excel 文件的示例代码。你可以将这段代码复制到你的项目中，并根据需要进行修改。如果你想要在浏览器中下载导出的 Excel 文件，可以将该控制器方法作为一个 Action 方法，并在 View 中添加一个链接或按钮，以便用户点击下载。
