I have Entity "Opportuniy" {ID/EntityName}
(0 -level of depth)

It's easy to get fields. This "Opportuniy" relates to 3 (for example) other entities (1-level depth)

These 3 entities from level-1 have 2 (for example) relating to other entities for each entity. (2-level depth)

So, it looks like some sort of tree:

 Opportunity:  
     |-entity 1
     |-entity 1-1
     |-entity 1-2  
     |-entity 2
     |-entity 2-1
     |-entity 2-2  
     |-entity 3
     |-entity 3-1
     |-entity 3-2

How can i retrieve this structure programatically, using C#?

I tried to use service.retrive(...) but here I must set ID and entity name for each entity. Can this structure be retrieved in single request?

Thank you

Hello,

I don't think you can use Retrieve for this purpose. You should use RetreiveMultiple combining it with FetchXml. To build proper FetchXml you can use XrmToolbox and FetchXmlBuilder plugin.
