我是靠谱客的博主忐忑朋友，最近开发中收集的这篇文章主要介绍EPPlus.Core导入导出Excel xlsx 文件，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

网上找了很多方法，感觉这是最简约直接的。

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。

涉及：一个视图index，控制器

视图index

@{
}
<h2>ASP.NET Core 导入导出Excel xlsx 文件</h2>
<a asp-action="Export">导出Excel</a>
<hr />
<form enctype="multipart/form-data" method="post" asp-action="Import">
<input type="file" name="excelfile" />
<input type="submit" value="上传" />
</form>

package.Save();

return File(sFileName, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
