如何使用链接按钮获取中继器中所选的值

我有一个链接按钮在我的中继器。lnkEdit和lnkDelete..我的问题是我如何分配选定的值和删除它?

这是我的代码:

protected void rptrInsurance_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    try
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            switch (e.CommandName)
            {
                case "Delete":
                    {
                        HCSInsurance oInsuranceDelete = new HCSInsurance();
                        Insurance oInsurance = new Insurance();
                       // oInsurance.InsuranceCode.ID = "2";
                        oInsuranceDelete.DeleteInsurance(oInsurance);
                    }
                    break;
                case "Edit":
                    {
                    }
                    break;
                default:
                    {
                    }
                    break;
            }
        }
    }
    catch (Exception ex)
    {
    }
}
