.Net Excel 導出圖表Demo(柱狀圖，多標簽頁)

1 使用插件名稱Epplus，多個Sheet頁數據應用，Demo為柱狀圖（Epplus支持多種圖表）

2 Epplus 的安裝和引用

   新建一個工程文件或控制台應用程式 打開 Vs2017 Tools 的Nuget 包管理器，使用命令 install-package Epplus 

3 開始在創建的工程中編寫代碼，實現功能

4 具體實現流程代碼如下：

  2 using OfficeOpenXml.Drawing;
  3 using OfficeOpenXml.Drawing.Chart;
  4 using OfficeOpenXml.Style;
  5 using System;
  6 using System.Collections.Generic;
  7 using System.Drawing;
  8 using System.IO;
