dataGridView绑定泛型的筛选功能实现

一次筛选

IList<Model> list = (IList<Model>)dataGridView2.DataSource;

var query = from student in list

//where student.FormCode.StartsWith(textBox3.Text.Trim())
where student.FormCode.Contains(textBox3.Text.Trim())
//where student.FormCode.EndsWith(textBox3.Text.Trim())

select student;
dataGridView2.DataSource = new LocalDataer.BindingCollection<Model>(query.ToList());

真正的仿绑定DataTable实现

var query = from student in listsouse

//where student.FormCode.StartsWith(textBox3.Text.Trim())
where student.FormCode.Contains(textBox3.Text.Trim())
//where student.FormCode.EndsWith(textBox3.Text.Trim())

select student;
dataGridView2.DataSource = new LocalDataer.BindingCollection<Model>(query.ToList());

这里的listsouse是一个不变的泛型集合，采用的是Linq查询，大家可以随意修改可实现不同效果，如果好的方法也请通知我，谢谢
