Question

正如我从谷歌搜索中了解到的那样，MSCRM 2011检索最多5000个实体，但我希望我的所有实体都来自营销列表。正如在Web上创建的，在HKLM \ Software \ Microsoft \ MSCRM上创建“TurnOffFetchThrottling”字段并将值设置为1可以解决此5000限制问题（此外，我在注册表中添加了MaxRowsPerPage字段并将其值设置为超过5000，但它也不起作用）。我试了一下，我得到了System.OutOfMemory Exception错误。顺便说一句，当我删除“”并只是获取id属性代码完美，但我需要所有属性。这是我的fetchxml代码：

enter code here
string fetchXml = "<fetch mapping='logical' >"
                  + "<entity name='" + entityType.LogicalName + "'>"
                    + "<all-attributes />"
                    + "<link-entity name='listmember' to='" + entityType.LogicalName + "id" + "' from='entityid'>"
                        + "<filter>"
                          + "<condition attribute='listid' operator='eq' value='" + chosenMarketingListGuid + "'/>"
                        + "</filter>"
                    + "</link-entity>"
                  + "</entity>"
                + "</fetch>";

我又尝试了一件事，我将fetchxml更改为：

enter code here
string fetchXml = "<fetch mapping='logical' >"
                  + "<entity name='listmember'>"
                    + "<all-attributes />"
                        + "<filter>"
                          + "<condition attribute='listid' operator='eq' value='" + chosenMarketingListGuid + "'/>"
                        + "</filter>"
                  + "</entity>"
                + "</fetch>";

如图所示，我尝试仅检索成员列表而不是联系人/主管/帐户enttiy类型，并且它有效！我需要联系人/主管/账户实体类型而非会员名单。如果有人帮我走出这条黑暗的MSCRM隧道，我将非常感激！

存在5000限制的原因是作为一个粗略的障碍来防止您遇到的问题。你已经绕过了软件限制，你现在需要克服硬件限制（内存不足）......

您没有说明您是如何编写代码或使用结果的，但我认为在执行查询后会有其他处理。在此基础上，我的建议是将分页引入查询表达式并以5000的批量处理记录。

一个粗略的例子：

// get records to process
string pagingCookie = null;
bool moreRecords = false;
int pageNum = 1;
DataCollection<Entity> myBatchOfRecords;    

bool continueProcessing = true;
while (continueProcessing)
{
    myBatchOfRecords = GetRecords(pageNum, ref pagingCookie, ref moreRecords);

    // process those records
    ProcessRecords(myBatchOfRecords);
    pageNum++;    
    continueProcessing = moreRecords;
}

function DataCollection<Entity> GetRecordsList(int pageNumber, ref string pagingCookie, ref bool moreRecords){
    var query = new QueryExpression(blahblahblah...);
    query.PageInfo = new PagingInfo { 
        Count = 5000, 
        PageNumber = pageNumber, 
        PagingCookie = pagingCookie };
    var results =  myOrgService.RetrieveMultiple(query);
    pagingCookie = matchedContacts.PagingCookie;
    moreRecords = matchedContacts.MoreRecords;
    return results;
}
