1、在vs程序中引用Spire.Xls.dll。（引用前需下载Spire.XLS for .NET包到本地）。
鼠标右键点击“引用”，“添加引用”，
2、添加本地路径中的spire.xls.dll文件
3、点击“ok”,完成引用
4、引用完成效果如图：
1、using Spire.Xls;
using System.Collections.Generic;
using System.Drawing;
using System.Drawing.Imaging;
namespace SaveShapeAsImage
{
class Program
{
static void Main(string[] args)
{
//创建Workbook对象
Workbook workbook = new Workbook();
//加载Excel文档
workbook.LoadFromFile("test.xlsx");
//获取第一个工作表
Worksheet sheet = workbook.Worksheets[0];
//创建SaveShapeTypeOption对象
SaveShapeTypeOption shapelist = new SaveShapeTypeOption();
//保存工作表中的形状和SmartArt图形为图片
List<Bitmap> images = sheet.SaveShapesToImage(shapelist);
int index = 0;
foreach (Image img in images)
{
img.Save("toImage" + index + ".Png", ImageFormat.Png);//这里的图片保存路径为程序文件夹路径（路径可自定义）
index++;
}
}
}
}
2、在程序项目文件夹下可查看保存的图片
1、Imports Spire.Xls
Imports System.Collections.Generic
Imports System.Drawing
Imports System.Drawing.Imaging
Namespace SaveShapeAsImage
Class Program
Private Shared Sub Main(args As String())
'创建Workbook对象
Dim workbook As New Workbook()
'加载Excel文档
workbook.LoadFromFile("test.xlsx")
'获取第一个工作表
Dim sheet As Worksheet = workbook.Worksheets(0)
'创建SaveShapeTypeOption对象
Dim shapelist As New SaveShapeTypeOption()
'保存工作表中的形状和SmartArt图形为图片
Dim images As List(Of Bitmap) = sheet.SaveShapesToImage(shapelist)
Dim index As Integer = 0
For Each img As Image In images
img.Save("toImage" + index + ".Png", ImageFormat.Png) '这里的图片保存路径为程序文件夹路径（路径可自定义）
index += 1
Next
End Sub
End Class
End Namespace
