从事件接收器更新另一个Web应用程序中的列表项

我试图以编程方式在项目事件接收器 another web application 中的文档库中创建一个文件夹 . 以下是我使用的代码：

public override void ItemAdded(SPItemEventProperties properties)
    {
        SPWeb web = properties.Web;
        Guid currListID = properties.ListId;
        int currListItemID = properties.ListItemId;


        try
        {
            SPSecurity.RunWithElevatedPrivileges(delegate()
            {
                using (SPSite site = new SPSite(web.Site.ID))
                {
                    using (SPWeb elevWeb = site.OpenWeb(web.ID))    
                    {
                        site.AllowUnsafeUpdates = true;
                        elevWeb.AllowUnsafeUpdates = true;
                        SPList elevList = elevWeb.Lists[currListID];
                        SPListItem elevCurrItem = elevList.GetItemById(currListItemID);



                        createProjectFolder(elevCurrItem.Title);



                        elevWeb.AllowUnsafeUpdates = false;
                        site.AllowUnsafeUpdates = false;
                    }
                }
            });
        }
        catch (Exception ex)
        {

        }

        base.ItemAdded(properties);
    }


private void createProjectFolder(string projectTitle)
    {
        try
        {
            SPSecurity.RunWithElevatedPrivileges(delegate()
          {
              using (SPSite spSite = new SPSite(SPSiteUrl))
              {
                  spSite.AllowUnsafeUpdates = true;
                  using (SPWeb spWeb = spSite.OpenWeb())
                  {
                      spWeb.AllowUnsafeUpdates = true;
                      SPList spList = spWeb.Lists[destListName];


                       SPListItem newFolder = spList.Items.Add("", SPFileSystemObjectType.Folder, projectTitle);
                       newFolder.Update();


                      spWeb.AllowUnsafeUpdates = false;
                  }
                  spSite.AllowUnsafeUpdates = false;
              }
          });


        }
        catch (Exception ex)
        {

        }
    }

但是我收到以下错误：

{“访问被拒绝 . （HRESULT异常：0x80070005（E_ACCESSDENIED））”}

Microsoft.SharePoint.SPGlobal.HandleUnauthorizedAccessException（UnauthorizedAccessException ex）at Microsoft.SharePoint.Library.SPRequest.GetListsWithCallback（String bstrUrl，Guid foreignWebId，String bstrListInternalName，Int32 dwBaseType，Int32 dwBaseTypeAlt，Int32 dwServerTemplate，UInt32 dwGetListFlags，UInt32 dwListFilterFlags，Boolean bPrefetchMetaData，布尔bSecurityTrimmed，布尔bGetSecurityData，布尔bPrefetchRelatedFields，ISP2DSafeArrayWriter p2DWriter，Int32和plRecycleBinCount）位于Microsoft.SharePoint.SPListCollection.EetureListsData（Guid webId，String strListName），位于ER.EPMProjectCenterList.ER_ProjectCenterItemAdded的Microsoft.SharePoint.SPListCollection.GetListByName（String strListName，Boolean bThrowException） . Microsoft.SharePoint.Utilities.SecurityContext.RunAsProcess（CodeToRunElevated secureCode）上的Microsoft.SharePoint.SPSecurity . <> c__DisplayClass5.b__3（）中的ER_ProjectCenterItemAdded . <> c__DisplayClass6.b__4（）

我知道我收到此错误，因为我试图访问列表跨域 . 是否有任何工作来实现这一目标 . 拜托我需要你的帮忙 .
