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);
