使用BindingList筛选DataGridView

public class CatalogueEntry
{
    private string _code;
    private string _desc;

    public CatalogueEntry(string code, string desc)
    {
        _code = code;
        _desc = desc;
    }

    public string Code => _code;
    public string Description => _desc;
}

目录列表(使用BindingList):

public class Catalogue : BindingList<CatalogueEntry>
{

}

初始化:

_catalogue = new Catalogue();

_catalogue.Add(new CatalogueEntry("BAGG", "It scares us all"));
_catalogue.Add(new CatalogueEntry("BIGG", "It embiggens us all"));
_catalogue.Add(new CatalogueEntry("BOGG", "It demeans us all"));
_catalogue.Add(new CatalogueEntry("BUGG", "It frightens us all"));

_source = new BindingSource();
_source.DataSource = _catalogue;

dataGridView.DataSource = _source;

我得到了上述数据的一个很好的网格。

var filter = "Description like 'scares'";
_source.Filter = filter;

什么都没有发生,即过滤器似乎不工作。我该怎么做才能让过滤器工作?

我猜底层数据源不是一个数据库,所以不会理解“像‘恐慌’一样的描述”。

编辑:如果我按以下方式更改过滤器:

var text = "scares";
var list = _catalogue.Where(entry => entry.Description.Contains(text));
_source.DataSource = list;
