使用DocumentFormat.OpenXml.DotNet.Core 1.0.1将数据导出到Excel

我需要在My MVC Core（EF Core）应用程序中将数据导出到Excel中。

在升级到Core之前，我在MVC 6（RC 1）中有一个工作代码（见下文）。

public class ExcelFileResult : FileResult { private object _model; private object _objT; private List<string> _columns; public ExcelFileResult(object model, List<string> columns, object objT) : base(new MediaTypeHeaderValue("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")) { _model = model; _columns = columns; _objT = objT; } protected override Task WriteFileAsync(HttpResponse response) { var enumerable = _model as System.Collections.IEnumerable; if (enumerable == null) { throw new ArgumentException("IEnumerable type required"); } byte[] FileContents = null; using (MemoryStream mem = new MemoryStream()) { using (var workbook = SpreadsheetDocument.Create(mem, DocumentFormat.OpenXml.SpreadsheetDocumentType.Workbook)) { var workbookPart = workbook.AddWorkbookPart(); workbook.WorkbookPart.Workbook = new DocumentFormat.OpenXml.Spreadsheet.Workbook(); workbook.WorkbookPart.Workbook.Sheets = new DocumentFormat.OpenXml.Spreadsheet.Sheets(); var sheetPart = workbook.WorkbookPart.AddNewPart<WorksheetPart>(); var sheetData = new DocumentFormat.OpenXml.Spreadsheet.SheetData(); sheetPart.Worksheet = new DocumentFormat.OpenXml.Spreadsheet.Worksheet(sheetData); DocumentFormat.OpenXml.Spreadsheet.Sheets sheets = workbook.WorkbookPart.Workbook.GetFirstChild<DocumentFormat.OpenXml.Spreadsheet.Sheets>(); string relationshipId = workbook.WorkbookPart.GetIdOfPart(sheetPart); uint sheetId = 1; if (sheets.Elements<DocumentFormat.OpenXml.Spreadsheet.Sheet>().Count() > 0) { sheetId = sheets.Elements<DocumentFormat.OpenXml.Spreadsheet.Sheet>().Select(s => s.SheetId.Value).Max() + 1; } DocumentFormat.OpenXml.Spreadsheet.Sheet sheet = new DocumentFormat.OpenXml.Spreadsheet.Sheet() { Id = relationshipId, SheetId = sheetId, Name = "Sheet1" }; sheets.Append(sheet); DocumentFormat.OpenXml.Spreadsheet.Row headerRow = new DocumentFormat.OpenXml.Spreadsheet.Row(); var allProperties = _objT.GetType().GetProperties(); var columns = _columns; List<System.Reflection.PropertyInfo> properties = new List<System.Reflection.PropertyInfo>(); foreach (string column in columns) { properties.Add(allProperties.FirstOrDefault(o => o.Name == column)); } foreach (var property in properties) { columns.Add(property.Name); DocumentFormat.OpenXml.Spreadsheet.Cell cell = new DocumentFormat.OpenXml.Spreadsheet.Cell(); cell.DataType = DocumentFormat.OpenXml.Spreadsheet.CellValues.String; cell.CellValue = new DocumentFormat.OpenXml.Spreadsheet.CellValue(property.Name); headerRow.AppendChild(cell); } sheetData.AppendChild(headerRow); foreach (var item in enumerable) { DocumentFormat.OpenXml.Spreadsheet.Row newRow = new DocumentFormat.OpenXml.Spreadsheet.Row(); foreach (var header in properties) { DocumentFormat.OpenXml.Spreadsheet.Cell cell = new DocumentFormat.OpenXml.Spreadsheet.Cell(); cell.DataType = DocumentFormat.OpenXml.Spreadsheet.CellValues.String; var value = header.GetValue(item); cell.CellValue = new DocumentFormat.OpenXml.Spreadsheet.CellValue(value?.ToString()); // newRow.AppendChild(cell); } sheetData.AppendChild(newRow); } sheetPart.Worksheet.Save(); workbook.WorkbookPart.Workbook.Save(); workbook.Close(); FileContents = mem.ToArray(); return response.Body.WriteAsync(FileContents, 0, FileContents.Length); } } } } 

我正在使用DocumentFormat.OpenXml：2.5.0 。 显然，现在代码与DocumentFormat.OpenXml.DotNet.Core 1.0.1命名空间不兼容。 而且我不能安装OpenXml 2.5.0包，因为它与dot net core不兼容。

有什么样的代码，我可以使用导出到Excel中的MVC核心？

以下是我的prject.json文件。

先谢谢你。
