特点

*
封装导入导出业务,目前仅支持 Excel，有兴趣的小伙伴可以考虑支持 CSV 以及PDF或其他格式的导出

*
配置特性即可控制相关逻辑和显示结果，无需修改逻辑代码

*
推荐配合导入导出DTO 使用

*
导出支持列头自定义处理以便支持多语言等场景

*
导出支持文本自定义过滤或处理

*
导入支持自动根据导入DTO生成导入模板及模板验证

*
导入支持数据验证逻辑

*
导入支持数据下拉选择

*
导入支持注释添加

普通导出

public class ExportTestData { public string Name1 { get; set; } public string
Name2 {get; set; } public string Name3 { get; set; } public string Name4 { get;
set; } } var result = await Exporter.Export(filePath, new List<ExportTestData>

11", }, new ExportTestData() { Name1 = "1", Name2 = "test", Name3 = "12", Name4
="11", } });

特性导出

public string Text { get; set; } [ExporterHeader(DisplayName = "普通文本")] public

列头处理或者多语言支持

[ExcelExporter(Name = "测试", TableStyle = "Light10")] public class

导入 Demo

导入特性（ImporterHeader）：

*
Name：string 表头显示名称(不可为空)。

*
Description：string 表头添加注释。

*
Author：string 注释作者，默认值为X.M。

导入结果（ImportModel<T>）：

*
Data：IList<T> 导入的数据集合。

*
ValidationResults：IList<ValidationResultModel> 数据验证结果。

*
HasValidTemplate：bool 模板验证是否通过。

数据验证结果（ValidationResultModel）：

*
Index：int 错误数据所在行。

*
Errors：IDictionary<string, string> 整个Excel错误集合。目前仅支持数据验证错误。

*
FieldErrors：IDictionary<string, string> 数据验证错误。
