Question

我有班级推销员

public class Salesman
{
    [BsonId]
    [BsonRepresentation(BsonType.ObjectId)]
    [JsonConverter(typeof(ObjectIdConverter))]
    public ObjectId Id { get; set; }

    [BsonElement("complementTime")]
    public DateTime ComplementTime { get; set; }

    [BsonElement("futureWorker")]
    public FutureWorkerInfo FutureWorker { get; set; }
}

和班级顾问

public class Consultant
{
    [BsonId]
    [BsonRepresentation(BsonType.ObjectId)]
    [JsonConverter(typeof(ObjectIdConverter))]
    public ObjectId Id { get; set; }

    [BsonElement("complementTime")]
    public DateTime ComplementTime { get; set; }

    [BsonElement("futureWorker")]
    public FutureWorkerInfo FutureWorker { get; set; }

    [BsonElement("recommendedWorkers")]
    public FutureWorkerInfo[] RecommendedWorkers { get; set; }       
}

这两个类都有类

 public class FutureWorkerInfo
{
    [BsonElement("name")]
    public string Name { get; set; }

    [BsonElement("homeAddress")]
    public FutureWorkerHomeAddress HomeAddress { get; set; }

    [BsonElement("phone")]
    public string Phone { get; set; }

    [BsonElement("secondPhone")]
    public string SecondPhone { get; set; }

    [BsonElement("email")]
    public string Email { get; set; }

    [BsonElement("birthDate")]
    public string BirthDate { get; set; }
}

我需要忽略字段＆＃34; homeAddress＆＃34;当我使用课程＆＃34;推销员＆＃34;。这意味着我不必仅在Salesman中插入或读取mongo数据库这个字段。当我使用顾问我应该＆＃39;可以＆＃39;一些操作与字段＆＃34; homeAddress＆＃34;。

Answer 1

您可以使用界面执行此操作。

创建ISalesmanFutureWorkInfo

public interface ISalesmanFutureWorkInfo
{
    string Name { get; set; }
    string Phone { get; set; }
    string SecondPhone { get; set; }
    string Email { get; set; }
    string BirthDate { get; set; }
}

创建一个具有HomeAddress的IConsultantFutureWorkInfo并继承ISalesmanFutureWorkInfo

public interface IConsultantFutureWorkInfo : ISalesmanFutureWorkInfo
{
    FutureWorkerHomeAddress HomeAddress { get; set; }
}

更改类以使用接口。

public class Consultant
{
    [BsonId]
    [BsonRepresentation(BsonType.ObjectId)]
    [JsonConverter(typeof(ObjectIdConverter))]
    public ObjectId Id { get; set; }

    [BsonElement("complementTime")]
    public DateTime ComplementTime { get; set; }

    [BsonElement("futureWorker")]
    public IConsultantFutureWorkInfo FutureWorker { get; set; }

    [BsonElement("recommendedWorkers")]       
    public IConsultantFutureWorkInfo[] RecommendedWorkers { get; set; }
}

public class Salesman
{
    [BsonId]
    [BsonRepresentation(BsonType.ObjectId)]
    [JsonConverter(typeof(ObjectIdConverter))]
    public ObjectId Id { get; set; }

    [BsonElement("complementTime")]
    public DateTime ComplementTime { get; set; }

    [BsonElement("futureWorker")]
    public ISalesmanFutureWorkInfo FutureWorker { get; set; }
}

Answer 2

[BsonElement("homeAddress")]
[BsonIgnoreIfNull]
public FutureWorkerHomeAddress HomeAddress { get; set; }

现在一切都还好

Bson忽略了字段
