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

导出 Demo
Demo1-1
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() { new ExportTestData() { Name1 = "1", Name2 = "test", Name3 = "12", Name4 = "11", }, new ExportTestData() { Name1 = "1", Name2 = "test", Name3 = "12", Name4 = "11", } });
Demo1-2
特性导出
[ExcelExporter(Name = "测试", TableStyle = "Light10")]public class ExportTestDataWithAttrs { [ExporterHeader(DisplayName = "加粗文本", IsBold = true)] public string Text { get; set; } [ExporterHeader(DisplayName = "普通文本")] public string Text2 { get; set; } [ExporterHeader(DisplayName = "忽略", IsIgnore = true)] public string Text3 { get; set; } [ExporterHeader(DisplayName = "数值", Format = "#,##0")] public double Number { get; set; } [ExporterHeader(DisplayName = "名称", IsAutoFit = true)] public string Name { get; set; } } var result = await Exporter.Export(filePath, new List() { new ExportTestDataWithAttrs() { Text = "啊实打实大苏打撒", Name="aa", Number =5000, Text2 = "w萨达萨达萨达撒", Text3 = "sadsad打发打发士大夫的" }, new ExportTestDataWithAttrs() { Text = "啊实打实大苏打撒", Name="啊实打实大苏打撒", Number =6000, Text2 = "w萨达萨达萨达撒", Text3 = "sadsad打发打发士大夫的" }, new ExportTestDataWithAttrs() { Text = "啊实打实速度大苏打撒", Name="萨达萨达", Number =6000, Text2 = "突然他也让他人", Text3 = "sadsad打发打发士大夫的" }, });
