1、安装引用ExcelReport(NPOI)

1）使用Nuget界面管理器

搜索"ExcelReport"和“ExcelReport.Driver.NPOI”,在列表中分别找到它，点击"安装"

相关文档：VS(Visual Studio)中Nuget的使用

2）使用Package Manager命令安装

PM> Install-Package ExcelReport -Version 3.1.6
PM> Install-Package ExcelReport.Driver.NPOI -Version 2.0.3

3）使用.NET CLI命令安装

> dotnet add package ExcelReport --version 3.1.6
> dotnet add package ExcelReport.Driver.NPOI --version 2.0.3

2、ExcelReport(NPOI)简单的参数替换渲染示例代码

using ExcelReport;
using ExcelReport.Driver.NPOI;
using ExcelReport.Renderers;
using System;
using System.Drawing;
namespace _1.参数渲染器示例
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            try
            {
                // 项目启动时，添加
                Configurator.Put(".xls", new WorkbookLoader());
                ExportHelper.ExportToLocal(@"Template\Template.xls", "out.xls",
                        new SheetRenderer("参数渲染示例",
                            new ParameterRenderer("String", "Hello World!"),
                            new ParameterRenderer("Boolean", true),
                            new ParameterRenderer("DateTime", DateTime.Now),
                            new ParameterRenderer("Double", 3.14),
                            new ParameterRenderer("Image", Image.FromFile("Image/C#高级编程.jpg"))
                            )
                        );
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
            }
            Console.WriteLine("finished!");
        }
    }
}

3、ExcelReport(NPOI)单行重复渲染

使用ExcelReport(NPOI)单行重复渲染生成Excel文件中的数据表格

using ExcelReport;
using ExcelReport.Driver.NPOI;
using ExcelReport.Renderers;
using System;
namespace _2.单行重复渲染示例
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            // 项目启动时，添加
            Configurator.Put(".xls", new WorkbookLoader());
            try
            {
                var num = 1;
                ExportHelper.ExportToLocal(@"Template\Template.xls", "out.xls",
                        new SheetRenderer("学生名册",
                            new RepeaterRenderer<StudentInfo>("Roster", StudentLogic.GetList(),
                                new ParameterRenderer<StudentInfo>("No1", t => num++),
                                new ParameterRenderer<StudentInfo>("Name", t => t.Name),
                                new ParameterRenderer<StudentInfo>("Gender", t => t.Gender ? "男" : "女"),
                                new ParameterRenderer<StudentInfo>("Class", t => t.Class),
                                new ParameterRenderer<StudentInfo>("RecordNo", t => t.RecordNo),
                                new ParameterRenderer<StudentInfo>("Phone", t => t.Phone),
                                new ParameterRenderer<StudentInfo>("Email", t => t.Email)
                                ),
                             new ParameterRenderer("Author", "hzx")
                            )
                        );
            }
            catch (Exception e)
            {
                Console.WriteLine(e);
            }
            Console.WriteLine("finished!");
            Console.ReadKey();
        }
    }
}
