示例代码

定义模型

public class ReportModel
{
    [Excel("My Title", Order=1)]
    public string Title { get; set; }
    
    [Excel("User Name", Order=2)]
    public string Name { get; set; }
}

创建模型列表

var models = new List<ReportModel>
{
    new ReportModel{Name="a", Title="b"},
    new ReportModel{Name="c", Title="d"},
    new ReportModel{Name="f", Title="e"}
};

对象转 Excel 文件

var exporter = new ExcelExporter();
var bytes = exporter.ObjectToExcelBytes(models);
File.WriteAllBytes("C:\\demo.xls", bytes);

Excel 文件转对象

var importer = new ExcelImporter();
IEnumerable<ReportModel> result = importer.ExcelToObject<ReportModel>("c:\\demo.xls");

// 也可以直接使用字节数组
// IEnumerable<ReportModel> result = importer.ExcelToObject<ReportModel>(bytes);

自动列宽(新特性)

// 启用自动列宽调整
var bytes = ExcelHelper.ObjectToExcelBytes(models, options =>
{
    options.ExcelType = ExcelType.Xlsx;
    options.AutoColumnWidth = true;        // 启用自动宽度
    options.MinColumnWidth = 8;            // 最小宽度(字符)
    options.MaxColumnWidth = 50;           // 最大宽度(字符)
    options.DefaultColumnWidth = 16;       // 禁用自动时的默认宽度
});

在 ASP.NET MVC 中使用

在 ASP.NET MVC 模型中,DisplayAttribute 可以像 ExcelTitleAttribute 一样被支持。
