.Net Excel 导出图表Demo(柱状图，多标签页)

1 使用插件名称Epplus，多个Sheet页数据应用，Demo为柱状图（Epplus支持多种图表）

2 Epplus 的安装和引用

新建一个工程文件或控制台应用程序 打开 Vs2017 Tools 的Nuget 包管理器，使用命令 install-package Epplus

3 开始在创建的工程中编写代码，实现功能

4 具体实现流程代码如下：

 using OfficeOpenXml;
 using OfficeOpenXml.Drawing;
 using OfficeOpenXml.Drawing.Chart;
 using OfficeOpenXml.Style;
 using System;
 using System.Collections.Generic;
 using System.Drawing;
 using System.IO;
 using System.Linq;
 using System.Text;
 using System.Threading.Tasks;

 namespace EpplusTest

         static void Main(string[] args)
         {
             FileInfo newFile = new FileInfo(@"d:\test.xlsx");
             if (newFile.Exists)
             {
                 newFile.Delete();
                 newFile = new FileInfo(@"d:\test.xlsx");
             }

             using (ExcelPackage package = new ExcelPackage(newFile))
