Answer 1

for(int i=0;i<gv_LoanList.Rows.Count();i++)
{
  CheckBox cb=gv_LoanList.Rows[i].FindControl("cbo_checked") as CheckBox ;
}foreach(GridViewRow row in gv_LoanList.Rows)
{
  CheckBox cb=row .FindControl("cbo_checked") as CheckBox ;
}

Answer 2

foreach (GridViewRow gvrow in this.grid.Rows)
            {
                CheckBox chkId = (CheckBox)gvrow.FindControl("chkId");
                if (chkId.Checked == true)
                {
                    //复选框选中
                }            }
