WeihanLi.Npoi 1.7.0 更新介绍

Intro

昨天晚上发布了 WeihanLi.Npoi 1.7.0 版本，增加了 ColumnInputFormatter/ ColumnOutputFormatter，又进一步增强了导入导出的灵活性，来看下面的示例

ColumnInputFormatter/ColumnOutputFormatter

示例 Model:

internal abstract class BaseEntity
{public int PKID { get; set; }
}
internal class TestEntity : BaseEntity
{public Guid SettingId { get; set; }public string SettingName { get; set; }public string DisplayName { get; set; }public string SettingValue { get; set; }public string CreatedBy { get; set; } = "liweihan";public DateTime CreatedTime { get; set; } = DateTime.Now;public string UpdatedBy { get; set; }public DateTime UpdatedTime { get; set; }public bool Enabled { get; set; }
}

示例配置：

var setting = ExcelHelper.SettingFor<TestEntity>();
// ExcelSetting
setting.HasAuthor("WeihanLi").HasTitle("WeihanLi.Npoi test").HasDescription("WeihanLi.Npoi test").HasSubject("WeihanLi.Npoi test");
setting.HasSheetConfiguration(0, "SystemSettingsList", 1, true);
// setting.HasFilter(0, 1).HasFreezePane(0, 1, 2, 1);
setting.Property(_ => _.SettingId).HasColumnIndex(0);
setting.Property(_ => _.SettingName).HasColumnTitle("SettingName").HasColumnIndex(1);
setting.Property(_ => _.DisplayName).HasOutputFormatter((entity, displayName) => $"AAA_{entity.SettingName}_{displayName}").HasInputFormatter((entity, originVal) => originVal.Split(new[] { '_' })[2]).HasColumnTitle("DisplayName").HasColumnIndex(2);
setting.Property(_ => _.SettingValue).HasColumnTitle("SettingValue").HasColumnIndex(3);
setting.Property(_ => _.CreatedTime).HasColumnTitle("CreatedTime").HasColumnIndex(4).HasColumnWidth(10).HasColumnFormatter("yyyy-MM-dd HH:mm:ss");
setting.Property(_ => _.CreatedBy).HasColumnInputFormatter(x => x += "_test").HasColumnIndex(4).HasColumnTitle("CreatedBy");
setting.Property(x => x.Enabled).HasColumnInputFormatter(val => "启用".Equals(val)).HasColumnOutputFormatter(v => v ? "启用" : "禁用");
setting.Property("HiddenProp").HasOutputFormatter((entity, val) => $"HiddenProp_{entity.PKID}");
setting.Property(_ => _.PKID).Ignored();
setting.Property(_ => _.UpdatedBy).Ignored();
setting.Property(_ => _.UpdatedTime).Ignored();

测试代码：

var entities = new List<TestEntity>()
{new TestEntity(){PKID = 1,SettingId = Guid.NewGuid(),SettingName = "Setting1",SettingValue = "Value1",DisplayName = "ddd1"},new TestEntity(){PKID=2,SettingId = Guid.NewGuid(),SettingName = "Setting2",SettingValue = "Value2",Enabled = true},
};
var path = $@"{tempDirPath}\test.xlsx";
entities.ToExcelFile(path);
var entitiesT0 = ExcelHelper.ToEntityList<TestEntity>(path);
