动态crm 4 -更新约会时出错

Question

我正在尝试添加更多所需的与会者。但是我正在运行错误，代码是-2146233087。

activityparty activityParty = new activityparty();         
activityParty.partyid = new Lookup();            
activityParty.partyid.Value = contact.contactid.Value;     
appointment.requiredattendees = new activityparty[] { activityParty };   
service.Update(appointment);

Answer 1

嗨，我终于发现了问题，我错过了实体的类型，并指出了问题。但是它只是将错误作为异常抛出而不告诉它，并且在添加类型之后它是固定的。

activityparty activityParty = new activityparty();         
activityParty.partyid = new Lookup();            
activityParty.partyid.Value = contact.contactid.Value;     
**activityParty.partyid.type = "contact";**
appointment.requiredattendees = new activityparty[] { activityParty };   
service.Update(appointment);
