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

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。
