Google Adwords API:在APIError上获取标准信息

有没有办法从APIError获取标准信息？

    MutateJobService mutateJobService = (MutateJobService)user.GetService(AdWordsService.v201309.MutateJobService);
    JobResult jobResult = mutateJobService.getResult(new BulkMutateJobSelector { includeStats = true, jobIds = jobIDs }); 
    SimpleMutateResult results = (SimpleMutateResult)jobResult.Item;
    if (results.errors != null)
    {
        foreach (ApiError apiError in results.errors)
        {
            // get criterion info
        }
    }

我发现很难获得有关特定错误的详细信息（这对于日志记录目的显然很重要）。任何帮助，不胜感激。
