.net framework导出Excel、Word、Pdf和Html：Magicodes.IE的简单使用

这里介绍一个很方便实用的库：Magicodes.IE，导入导出通用库，通过导入导出DTO模型来控制导入和导出，支持Excel、Word、Pdf和Html。

本篇介绍基本使用方法，使用方法非常简单，不需要学习npoi的应用。

在vs中，新建一个控制台项目（测试用，可以建其他项目，比如asp.net mvc ,winform都可以）

右键单击项目中的引用，选择nuget包管理，导入nuget包：这里只使用excel，所以只导入了Magicodes.IE.Excel

Magicodes.IE.Core
Magicodes.IE.Excel
Magicodes.IE.Pdf
Magicodes.IE.Word
Magicodes.IE.Html

1. 首先准备好一个类，这个类包含需要导出的属性一、导出数据

public class Question
{
    public string Title { get; set; }
    public string Content { get; set; }
    public string Options { get; set; }
    public string Answer { get; set; }
}

2.导出方法

这里如果new List<Question>()不设置数据，就可以直接导出Question的模板

static void ExportQuestion()
        {
            //这里需要补充，如果路径不存在要创建路径，否则会报错
            var filePath = Path.Combine(Directory.GetCurrentDirectory(), "TestFiles", "question.xlsx");
            var exporter = new ExcelExporter();
            var result = exporter.Export(filePath, new List<Question>() {
                new Question()
                {
                    Title = "Question1",
                    Content = "Question content 1",
                    Options = "A:option1,B:option2,C:option3,D:option4",
                    Answer = "A",
                },
                new Question()
                {
                    Title = "Question2",
                    Content = "Question content 2",
                    Options = "A:option11,B:option22,C:option33,D:option43",
                    Answer = "B",
                }
            });
        }

其他方法参考下代码吧：

            await Import3();
            Console.WriteLine("Hello World!");
        }
