C# code

     for (int i = 0; i < rptFriend.Items.Count; i++)        {            if ((rptFriend.Items[i].FindControl("chkId") as CheckBox).Checked)            {                         }        }
------解决方案--------------------------------------------------------
foreach (Control ctl in Repeater1.Controls)
       {
           if (ctl is CheckBox)
           {
               (ctl as CheckBox).Checked = true;
           }
       }

  CheckBox check = (CheckBox)c.FindControl("cbDelete1");
if( check != null )
  {
    check.Checked = true;
  }
}
