textBoxXingMing.Text = this.dataGridView1.CurrentRow.Cells["姓名"].Value.ToString();
textBoxXinBie.Text = this.dataGridView1.CurrentRow.Cells["性别"].Value.ToString();
textBoxBuMenHao.Text = this.dataGridView1.CurrentRow.Cells["部门号"].Value.ToString();
textBoxZhiCheng.Text = this.dataGridView1.CurrentRow.Cells["职称"].Value.ToString();
