Question

I’m running a small test on a WCF service, so I’m loading up 1000 accounts, and for each I want to call a method that returns an object. I’m missing something here, as the runAccount method is never called.

 private static void RunTest()
    {
        var accounts = CsvHelper.ParseCsv(@"Data\acccounts.csv");

        GeneralHelper.MemberData = (from a in accounts.AsParallel()
                                    select runAccount(a)) as IList<MemberFormDataContract>; //PLINQ
    }


    private static MemberFormDataContract runAccount(Account acct)
    {
        IAccountMasterService accountMasterService = new AccountMasterServiceClient();
        MemberFormDataContract memberFormDataContract = accountMasterService.FindMemberFormByAccountId(acct.Id);
        return memberFormDataContract;
    }

the point here is that I want to run the call for each account in the list, and populate a helper class with the results that is timing the calls and looking for high/low and an average. the problem is that the actual call to the service is never made, which helps the number look fantastic, but totally bogus.

Answer 1

Replace as IList<MemberFormDataContract> by ToList(). The execution of your select statement is deferred until you force it to be executed by (e.g.) ToList().
