在2个DataGridViews之间移动记录

Question

我有2个GridView，当我选择行时，我想将记录从DataGridView1抛出到DataGridView2。

代码如下：
当我点击按钮时，它不会播放所有项目。

    stuList.Add(new Student() { id=1,Name = "Jacob", Age = 29, City = "London" });
    stuList.Add(new Student() { id=2,Name = "Zulia", Age = 31, City = "London" });
    stuList.Add(new Student() { id=3,Name = "Brandon", Age = 35, City = "London" });

    defaultDGV.DataSource = stuList;

    foreach (DataGridViewRow row in defaultDGV.Rows)
    {
        if (row.Cells[0].Value != null)
        {
            string str = row.Cells[1].Value.ToString();
            var record = stuList.FirstOrDefault(a => a.Name.Equals(str));
            newList.Add(record);
            stuList.Remove(record);

        }
    }

    newDGV.DataSource = defaultDGV.DataSource = null;
    newDGV.DataSource = stuList;
    defaultDGV.DataSource = newList;

我发现var record = stuList.FirstOrDefault (a => a.Name.Equals (str));正在做一些我不知道的事情。
