.NET 核心中的 FetchXML - CRM Web API

Question

I'm learning how to use CRM Web API with .NET Core to work with entities and I found this very useful library . There is an option to retrieve record data using FetchXML .

string fetchXml = "<fetch mapping='logical'><entity name='account'><attribute name='accountid'/><attribute name='name'/></entity></fetch>";
var fetchResults = await api.GetList("accounts", QueryOptions: new CRMGetListOptions() { FetchXml = fetchXml });

Is there any option how to compose more easily and elegantly the fetchXML , for example by using QueryExpression ( Microsoft.CrmSdk.CoreAssemblies ) or something similar?

Answer 1

1. Design the Advanced find query & download the fetchxml
2. Develop fetchxml queries using XrmToolBox FetchXML builder

You can use QueryExpressionToFetchXmlRequest to convert the QueryExpression into FetchXml.

I have found Mike Ochs's FetchXmlWrapper helpful in certain projects.
