如何将数千条记录导入CRM？
我有一个列表，可能有数千条记录，并希望在CRM中创建记录。

目前我有一个方法接收列表调用另一种方法，它创建批量为200的记录，直到创建整个列表。
最初它一次是1000，因为这是ExecuteMultipleRequest的限制，但有时超时。
不能增加ExecuteMultipleRequest的限制。

此方法传递整个列表

    /* Receives a list of Entity Records and executes an executemultiplerequest, Returns false if any fail */
    public bool CreateStagingRecords<T>(List<T> records) where T : Entity
    {
        try
        {
            return CreateStagingRecordsInBatches(records, 0, records.Count);
        }
        catch { }
        return false;
    }

此方法以小块递归方式导入列表

    /* int start is used both as the start point to process the list and as subImportNo **/
    private bool CreateStagingRecordsInBatches<T>(List<T> records, int start, int end, int tries=0) where T : Entity
    {
        var createAmount = (end - start > 200) ? 200 : end - start; // 200 or the difference between end and start
        var records200 = records.Skip(start).Take(createAmount);
        var multipleRequest = new ExecuteMultipleRequest
        {
            Settings = new ExecuteMultipleSettings { ContinueOnError = false, ReturnResponses = true },
            Requests = new OrganizationRequestCollection()
        };
        foreach (var staging in records200)
        {
            multipleRequest.Requests.Add(new CreateRequest { Target = staging });
        }
        ExecuteMultipleResponse responses = null;
        try
        {
            responses = (ExecuteMultipleResponse)service.Execute(multipleRequest); // this can timeout
        }
        catch (System.TimeoutException) // The request timed out
        {
            if (tries < 4) // re-try if this is not already been retried 5 times
                return this.CreateStagingRecordsInBatches(records, start, end, tries + 1);
            return false; // we have already tried too many times, abandon the entire import
        }
        foreach (var response in responses.Responses)
        {
            if (response == null || response.Fault != null) //error
            {
                if (tries < 4)
                    return this.CreateStagingRecordsInBatches(records, start, end, tries+1);
                return false; // response not good, rather than trying to recover, abandon this import
            }
        }
        if (createAmount == 200 && start + 200 < end) // if createAmount is less than 200 then everything has been created, and start+200 is not equal to or more than end
        {                
            return this.CreateStagingRecordsInBatches(records, start + 200, end); // create the next 200 or less stagings records with the sub-import number incremented
        }
        return true; // this should only happen if there are under 200 records
    }

上述方法有效，但由于这是一个常见问题，我想知道其他开发人员如何处理它。

这是建议的方法之一，特别是如果你想要更严格的程序控制。
