}<br>清除datagridview的英文列，并且绑定数据

{<br>确保一个工号只能添加一次

}
}<br>添加一个员工信息

}
这是删除的代码
private void toolStripButton3_Click(object sender, EventArgs e)
{
提示点击是才会删除
DialogResult result = MessageBox.Show("提示","是否删除",MessageBoxButtons.YesNo,MessageBoxIcon.Question);
if(result==DialogResult.Yes)
{
string id = dgvList.SelectedRows[0].Cells[0].Value.ToString();
//string id = dgvList.SelectedCells[0].Value.ToString();
如果ID和我选中的ID相等才会删除
foreach (Worker item in Worker.list)
{
if(item.ID==id)
{
Worker.list.Remove(item);
break;
}
}
}
//dgvList.AutoGenerateColumns = false;
dgvList.DataSource = new BindingList(Worker.list);
}
