Aspose.Words生成饼图，柱状图，NET Core环境

Posted 2022-10-17 棉晗榜

开发环境

• C#
• .NET6

需要引用的组件

• System.Drawing.Common
• System.Security.Permissions
• Aspose.Words 22.5

参考代码：

Program.cs

// See https://aka.ms/new-console-template for more information
using Aspose.Words;
using ConsoleAppNET6._0;
using System;
using System.Data;

Console.WriteLine("Hello, World!");
 
//注册编码提供程序
System.Text.Encoding.RegisterProvider(System.Text.CodePagesEncodingProvider.Instance);

string file = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "1223.docx");

//测试生成饼图
Aspose.Words.Document doc = new Aspose.Words.Document();
DocumentBuilder builder = new DocumentBuilder(doc);

//builder.Writeln("普通饼图：");
MakeShape.AddPieChart(builder, "饼图测试1");

builder.Writeln();
//builder.Writeln("3D饼图：");
//AddPie3dChart(builder);
//柱状图
MakeShape.ColumnChart(builder);

//string file = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "1223.docx");
doc.Save(file, SaveFormat.Docx);

Console.WriteLine("图表生成成功");
