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:

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
