我正在尝试从CRM中检索实体列表,但我想让每个实体都与相关实体相关联.到目前为止,我有以下代码:

FilterExpression filterExpression = new FilterExpression();
ConditionExpression condition = new ConditionExpression(Constants.ModifiedOnAttribute, ConditionOperator.GreaterEqual, lastSync);
filterExpression.AddCondition(condition);

QueryExpression query = new QueryExpression()
{
     EntityName = entityName,
     ColumnSet = new ColumnSet(attributesMetadata.Select(att => att.Name).ToArray<string>()),
     Criteria = filterExpression,
     Distinct = false,
     NoLock = true
};

RetrieveMultipleRequest multipleRequest = new RetrieveMultipleRequest();
multipleRequest.Query = queryExpression;

RetrieveMultipleResponse response = (RetrieveMultipleResponse)proxy.Execute(multipleRequest);

在变量响应中,我可以看到EntityCollection属性,但在内部,相关实体总是空的.

我想知道是否可以使用RetrieveMultipleRequest检索具有相关实体的给定实体的集合,而不是使用RetrieveRequest逐个检索.
