Error on System.Linq.Enumerable. TakeIterator d__3a`1.MoveNext()

Question

I have the following code to iterate over subwebs of a sharepoint site. If I debug it line by line, it never goes to my catchs.
however on the uls logs I have this exception which I dont know what it means or if I should worry
53b416d1-1497-4b40-beb5-cd261180ece8 Stack trace:
at Microsoft.SharePoint.SPWeb.get_Created()
at xx.SP.DMS.WebParts.WebParts.LastCreatedJobs.LastCreatedJobs.<>c__DisplayClass8.<LoadGridData>b__7(SPWeb d)

at System.Linq.EnumerableSorter`1.Sort(TElement[] elements, Int32 count)
at System.Linq.OrderedEnumerable`1.<GetEnumerator>d__0.MoveNext()
at System.Linq.Enumerable.<TakeIterator>d__3a`1.MoveNext()
My code is as follows
private void LoadGridData()
try
String currentUrl = SPContext.Current.Site.Url;
var jobInfoList = new List<JobInfo>();
SPSecurity.RunWithElevatedPrivileges(delegate
using (var clientSiteCollection = new SPSite(currentUrl))
foreach (
SPWeb web in
clientSiteCollection.AllWebs.AsSafeEnumerable().Where(
c =>
c.AllProperties[Constants.WebProperties.General.WebTemplate] != null &&
c.AllProperties[Constants.WebProperties.General.WebTemplate].ToString() ==
Constants.WebTemplates.JobWebPropertyName).OrderByDescending(d => d.Created).Take(5)
if (web.DoesUserHavePermissions(SPContext.Current.Web.CurrentUser.LoginName,
SPBasePermissions.Open))
web.Dispose();
_lastCreatedJobsGrid.DataSource = jobInfoList;
_lastCreatedJobsGrid.DataBind();
catch (Exception ex)
LoggingService.LogError(LoggingCategory.Job, ex);
Any idea what could be the cause and solution if needed?

Answer 1

Few questions around your code.
1. jobInfoList variable has not assigned any data.
2. Why are you disposing the object in between the loop? Move that to outside.
3. Take below into different variable and use new variable in  foreach loop.
clientSiteCollection.AllWebs.AsSafeEnumerable().Where(
c =>
c.AllProperties[Constants.WebProperties.General.WebTemplate] != null &&
c.AllProperties[Constants.WebProperties.General.WebTemplate].ToString() ==
Constants.WebTemplates.JobWebPropertyName).OrderByDescending(d => d.Created).Take(5)
