如何获取 C# 中 IOrg.associate 的查找字段的 GUID？

Question

I've tried to get the GUID of a record using a lookup field value

var installationSiteEntity = new Entity("csp_installationsite");
var serviceSite = installationSiteEntity.GetAttributeValue<string>("cr3aa_servicesite");

Then I've used service.Associate("account", serviceSite, servicesiteOpp, newCollection);

But I get the error it can't convert string to guid, how do I get the GUID lookup value from this field?

Answer 1

Try getting it as an entity reference

var serviceSite = installationSiteEntity.GetAttributeValue<EntityReference>("cr3aa_servicesite");
service.Associate("account", serviceSite.id, servicesiteOpp, newCollection);

or covert the string back to a guid.

service.Associate("account", new Guid(serviceSite), servicesiteOpp, newCollection);
