对控件DataGridView1绑定：

List<Student> li=new List<Student>();
Student st1=new Student(1,"张三",20,"男");
li.Add(st1);
dataGridView1.DataSource=li;

如果通过TextBox 输入来查询：

List<Student> li = new List<Student>();
Student st1 = new Student(1, "张三", 20, "男");
Student st2 = new Student(2, "李四", 21, "男");
Student st3 = new Student(3, "王五", 22, "男");
Student st4 = new Student(4, "小红", 21, "女");
li.Add(st1);
li.Add(st2);
li.Add(st3);
li.Add(st4);
List<Student> li1 = new List<Student>();
foreach (Student item in li)
{
    if (item.Name.Contains(TextBox.Text.Trim()))
    {
        li1.Add(item);
    }

}
dataGridView1.DataSource = li1;
