I cannot get to the bottom of this error because it happens only in one instance, and I can't find any code that can be the cause of the error.
I have a 3.5 web service that I'm calling from a multi-threaded, CAB client. I have a bunch of unit tests against the web service (from both 3.5 and 2.0 code), and it works fine. However, in the actual application, it doesn't work 90% of the time and, the remaining 10% of the time, it decides to work.
Friend Function ExecuteSearch(ByVal query As String) As List(Of SomeObject) Dim searchResults As List(of Object) = _searcher.UserSearch(query) Return searchResults End Function // In Searcher Public Function UserSearch(ByVal query As String) As List(Of SomeObject) Return Translate(Search.GetResults(query)) End Function // In Search Public Function GetResults(ByVal query As String) As List(Of SomeObject) Dim service As New FinderService.FinderService() Dim results As New List(Of String) Dim serviceResults As IEnumerable(Of String) = service.Search(query) // <-- ERRORS OUT HERE results.AddRange(serviceResults) Return results End Function // In the service Public Function Search(ByVal query As String) As IEnumerable(Of String) Initialize() // Initializes the _accounts variable Dim results As New List(of String) For Each account As User In _accounts If a bunch of conditions Then results.Add(account.Name) End IF End For Return results End Function
The breakpoints hit these codes (in this order). The line that errors out is in the "GetResults" method.
Any help would be appreciated.
