各位大侠，这样子代码为什么在textbox输入数值后，datagridview中没选中相应的行数据，没反应？？？？

private void textBox4_TextChanged(object sender, EventArgs e)
{
foreach (DataGridViewRow each in dataGridView1.Rows)
{
if (textBox4.Text == this.dataGridView1.CurrentRow.Cells["序号"].Value.ToString())
{
this.dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;

}
}

}
