ASP.NET Core 使用EPPlus.Core导入导出Excel xlsx 文件,EPPlus.Core支持Excel 2007/2010 xlsx文件导入导出,可以运行在Windows, Linux和Mac。
EPPlus.Core 是基于EPPlus 更改而来,在Linux 下需要安装libgdiplus 。
EPPlus:http://epplus.codeplex.com/
EPPlus.Core:https://github.com/VahidN/EPPlus.Core
下面在ASP.NET Core 中导入导出Excel xlsx 文件。
新建项目
新建一个ASP.NET Core Web Application 项目ASPNETCoreExcel,选择Web 应用程序 不进行身份验证。
然后添加EPPlus.Core 引用。
使用NuGet 命令行:
Install-Package EPPlus.Core
也可以使用NuGet包管理器安装。

public class XlsxController : Controller { private IHostingEnvironment _hostingEnvironment; public XlsxController(IHostingEnvironment hostingEnvironment) { _hostingEnvironment = hostingEnvironment; } public IActionResult Index() { return View(); } public IActionResult Export() { string sWebRootFolder = _hostingEnvironment.WebRootPath; string sFileName = $ "{Guid.NewGuid()}.xlsx" ; FileInfo file = new FileInfo(Path.Combine(sWebRootFolder, sFileName)); using (ExcelPackage package = new ExcelPackage(file)) { // 添加worksheet ExcelWorksheet worksheet = package.Workbook.Worksheets.Add( "aspnetcore" ); //添加头 worksheet.Cells[1, 1].Value = "ID" ; worksheet.Cells[1, 2].Value = "Name" ; worksheet.Cells[1, 3].Value = "Url" ; //添加值 worksheet.Cells[ "A2" ].Value = 1000; worksheet.Cells[ "B2" ].Value = "LineZero" ; worksheet.Cells[ "C2" ].Value = "http://www.cnblogs.com/linezero/" ; worksheet.Cells[ "A3" ].Value = 1001; worksheet.Cells[ "B3" ].Value = "LineZero GitHub" ; worksheet.Cells[ "C3" ].Value = "https://github.com/linezero" ; worksheet.Cells[ "C3" ].Style.Font.Bold = true ; package.Save(); } return File(sFileName, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" ); } } |
通过依赖注入获取HostingEnvironment,对应可以获取程序的相关目录及属性。
然后添加Index 视图增加一个链接导出Excel

[HttpPost] public IActionResult Import(IFormFile excelfile) { string sWebRootFolder = _hostingEnvironment.WebRootPath; string sFileName = $ "{Guid.NewGuid()}.xlsx" ; FileInfo file = new FileInfo(Path.Combine(sWebRootFolder, sFileName)); try { using (FileStream fs = new FileStream(file.ToString(), FileMode.Create)) { excelfile.CopyTo(fs); fs.Flush(); } using (ExcelPackage package = new ExcelPackage(file)) { StringBuilder sb = new StringBuilder(); ExcelWorksheet worksheet = package.Workbook.Worksheets[1]; int rowCount = worksheet.Dimension.Rows; int ColCount = worksheet.Dimension.Columns; bool bHeaderRow = true ; for ( int row = 1; row <= rowCount; row++) { for ( int col = 1; col <= ColCount; col++) { if (bHeaderRow) { sb.Append(worksheet.Cells[row, col].Value.ToString() + "\t" ); } else { sb.Append(worksheet.Cells[row, col].Value.ToString() + "\t" ); } } sb.Append(Environment.NewLine); } return Content(sb.ToString()); } } catch (Exception ex) { return Content(ex.Message); } } |
运行程序打开http://localhost:5000/xlsx
上传对应文件,显示如下。
