Question

我正在尝试检索其所需的约会＆＃34;包含在帐户列表中的一个实体上。 requiredattendees有一种PartyList。我的查询如下：

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.

我收到了以下错误：

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，那么预约就是一样的。希望这有帮助

QueryExpression qe = new QueryExpression
{
    EntityName = "serviceappointment",
    Criteria = new FilterExpression
    {
        FilterOperator = LogicalOperator.And,
        Conditions = 
        {
            new ConditionExpression
            {
                AttributeName = "scheduledstart", 
                Operator = ConditionOperator.LessThan,
                Values = 
                {
                    endTime
                }
            },
            new ConditionExpression
            {
                AttributeName = "scheduledend",
                Operator = ConditionOperator.GreaterThan,
                Values =
                {
                    startTime
                }
            }
        }
    },
    LinkEntities = 
    {
        new LinkEntity
        {
            LinkFromEntityName = "activitypointer",
            LinkFromAttributeName = "activityid",
            LinkToEntityName = "activityparty",
            LinkToAttributeName = "activityid",
            LinkCriteria = new FilterExpression
            {
                FilterOperator = LogicalOperator.And,
                Conditions = 
                {
                    new ConditionExpression
                    {
                        AttributeName = "partyid",
                        Operator = ConditionOperator.Equal,
                        Values = 
                        {
                            someEntity.id
                        }
                    }
                }
            }
        }
    }
};
