C# 如何向活动添加资源？

是否可以将资源用户/设施添加到服务约会

以下是我要添加资源的记录：

        var serviceAppointment = this.organizationService.Retrieve(
            "serviceappointment",
            serviceActivityGuid,
            new ColumnSet(true));

{
  "ListOfResourceIds": [
    {
      "partyid": "9CDC2C51-6417-4550-A0FE-D825EE75D333"
    },
    {
      "partyid": "9CDC2C51-6417-4550-A0FE-D825EE75D044"
    }
  ]
}

var serviceAppointment = organizationService.Retrieve(
                      "serviceappointment",
                      serviceActivityGuid,
                      new ColumnSet(true));

var updateServiceAppointment = new Entity("serviceappointment")
{
    Id = serviceAppointment.Id
};
updateServiceAppointment["resources"] = new[]
{
    new ActivityParty()
    {
        PartyId = new CrmEntityReference("systemuser", correspondingSystemUserId)
    }
};
organizationService.Update(updateServiceAppointment);

我有一份资源清单：

        var serviceAppointment = this.organizationService.Retrieve(
            "serviceappointment",
            serviceActivityGuid,
            new ColumnSet(true));

{
  "ListOfResourceIds": [
    {
      "partyid": "9CDC2C51-6417-4550-A0FE-D825EE75D333"
    },
    {
      "partyid": "9CDC2C51-6417-4550-A0FE-D825EE75D044"
    }
  ]
}

var serviceAppointment = organizationService.Retrieve(
                      "serviceappointment",
                      serviceActivityGuid,
                      new ColumnSet(true));

var updateServiceAppointment = new Entity("serviceappointment")
{
    Id = serviceAppointment.Id
};
updateServiceAppointment["resources"] = new[]
{
    new ActivityParty()
    {
        PartyId = new CrmEntityReference("systemuser", correspondingSystemUserId)
    }
};
organizationService.Update(updateServiceAppointment);

如何将这些资源添加到上面的ServiceAppointment

我怀疑在添加它们之后，我会调用：

        organizationService.Update(serviceAppointment);

资源属于SystemUser类型。要更新服务预约，请获取资源的相应系统用户ID：

        var serviceAppointment = this.organizationService.Retrieve(
            "serviceappointment",
            serviceActivityGuid,
            new ColumnSet(true));

{
  "ListOfResourceIds": [
    {
      "partyid": "9CDC2C51-6417-4550-A0FE-D825EE75D333"
    },
    {
      "partyid": "9CDC2C51-6417-4550-A0FE-D825EE75D044"
    }
  ]
}

var serviceAppointment = organizationService.Retrieve(
                      "serviceappointment",
                      serviceActivityGuid,
                      new ColumnSet(true));

var updateServiceAppointment = new Entity("serviceappointment")
{
    Id = serviceAppointment.Id
};
updateServiceAppointment["resources"] = new[]
{
    new ActivityParty()
    {
        PartyId = new CrmEntityReference("systemuser", correspondingSystemUserId)
    }
};
organizationService.Update(updateServiceAppointment);

非常感谢你！这会抹去资源中的所有内容并替换为1 ActivityParty记录吗？
