我有一個帶有itemadded事件接收器的文檔庫。文檔庫中的項目是文檔集。ItemAdded如何檢測添加的項目是文檔集本身還是文檔到文檔庫
當我在文檔庫中創建一個項目時，添加的項目被執行。然而，這個邏輯，我只想爲文檔集本身執行它，而不是當我將文件添加到文檔集時。創建文檔時設置的，但行
下面的代碼工作正常：
string recurrent = item[Meetings.Common.Constants.FIELDS_AGENDAPOINTSRECURRENT_NAME].ToString();
拋出的對象引用異常時，當一個文件被上傳到文件執行事件接收器設置
public override void ItemAdded(SPItemEventProperties properties)
{
Logger.LogDebug("AgendaPointsProposedEvents", "ItemAdded(SPItemEventProperties properties)", "BEGIN");
base.ItemAdded(properties);
try
{
base.EventFiringEnabled = false;
SPListItem item = properties.ListItem;
SPItemEventDataCollection afterProperties = properties.AfterProperties;
string listName = item.ParentList.RootFolder.Name;
string recurrent = item[Meetings.Common.Constants.FIELDS_AGENDAPOINTSRECURRENT_NAME].ToString();
bool recurrentBln = bool.Parse(recurrent);
if (recurrentBln)
{
#region NLNSSV-169
// If the user selects recurrent the agenda proposed item cant have an associated meeting.
// Also the security is reset to its initial state.
properties.ListItem[Meetings.Common.Constants.FIELDS_MEETING_NAME] = null;
properties.List.ResetRoleInheritance();
properties.ListItem.Update();
#endregion
