c# - 带有 PartyList 的 QueryExpression 中的错误

Question

我正在尝试检索其“requiredattendees”包含在帐户列表中的实体之一上的约会。 requiredattendees 有一种 PartyList。我的查询看起来像:

var query = new QueryExpression("appointment")
{
      ColumnSet = columnSet,
      Criteria = new FilterExpression(LogicalOperator.Or)
};

并添加条件:

GetAccounts()
.Select(a => new ConditionExpression("requiredattendees", ConditionOperator.Contains, a.Id))
.ForEach(c => query.Criteria.AddCondition(c));


a.Id is the account guid.

我收到以下错误:

Cannot add attribute requiredattendees of type partylist in a condition
System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral]]

此代码用于服务预约，但如果我没记错的话，预约也是一样的。希望这有帮助

QueryExpression qe = new QueryExpression

    EntityName = "serviceappointment",
    Criteria = new FilterExpression
