Linux中.NET读取excel组件，不会出现The type initializer for ‘Gdip‘ threw an exception异常

组件，可通过nuget安装，直接搜名字：
ExcelDataReader
在这里插入图片描述

using ConsoleAppReadFileData.Model;
using ExcelDataReader;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace ConsoleAppReadFileData.FileRead
