cs代码：

//删除好友
protected void DataListFriend_OnClick(object source, DataListCommandEventArgs e)
{
int toId = Convert.ToInt32(DataListFriend.DataKeys[e.Item.ItemIndex].ToString());//获取删除列的主键
if (e.CommandName == "DeleteFriend")
{
//true表示删除双方的好友关系，false表示只删除单方的好友关系
if (_friendService.DeleteFriend(_userId, toId,true) > 0)
{
CommonManager.ShowMessageBox(Page, GetType(), "删除好友成功！", CommonManager.MessageType.Information,
CommonManager.PageType.PageWithAjaxAndWithJump, "FriendList.aspx");
}
