通用IBindingListView实现

Question

任何人都可以建议实现通用集合类的良好实现,实现IBindingListView&IBindingList接口并提供过滤和搜索功能吗？

我将目前的选项视为:

• 使用其他人编写和测试过的类
• 继承BindingList<T>和实现IBindingListView接口
• 从头开始编写自定义集合,实现IBindingListView和IBindingList.

显然,第一个选择是我的首选.

我使用并构建了几年前我在MSDN论坛上发现的一个实现,但最近我再次搜索并找到了一个名为BindingListView的sourceforge项目.它看起来很不错,我还没有把它拉进去替换我的黑客版本.

nuget包: Equin.ApplicationFramework.BindingListView

示例代码:

var lst = new List<DemoClass>
{
    new DemoClass { Prop1 = "a", Prop2 = "b", Prop3 = "c" },
    new DemoClass { Prop1 = "a", Prop2 = "e", Prop3 = "f" },
    new DemoClass { Prop1 = "b", Prop2 = "h", Prop3 = "i" },
    new DemoClass { Prop1 = "b", Prop2 = "k", Prop3 = "l" }
};
dataGridView1.DataSource = new BindingListView<DemoClass>(lst);
// you can now sort by clicking the column headings 
//
// to filter the view...
var view = (BindingListView<DemoClass>)dataGridView1.DataSource;            
view.ApplyFilter(dc => dc.Prop1 == "a");
