更新约会时出错

Question

我正在尝试添加更多必需的与会者。但是我遇到了错误，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atlast我发现了这个问题，我错过了实体的类型并解决了问题。但它只是简单地将错误作为异常抛出而没有告诉它，并且在添加类型之后它已被修复。

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);
