C＃：如何將類屬性公開給一個類，而不公開給另一個類？

Question

我的類庫中有一個數據協定“ StudentInformation”，如下所示：

public class StudentInformation
{
    public int StudentId { get; set; }
    public bool CanChangeBus { get; set; }
    public List<int> AvailableBuses { get; set; }
}

public class BusChangeRequestModel
{
    public StudentInformation StudentInfo { get; set; }
    ...
    ...
}

public class BusChangeResponseModel
{
    public StudentInformation StudentInfo { get; set; }
    ...
}

Request模型發送StudentId，類庫處理信息並填充屬性“ CanChangeBus”和“ AvailableBuses”，然后在響應模型中將其返回。

我想從請求模型中隱藏屬性“ CanChangeBus”和“ AvailableBuses”。 如果我將這些屬性的設置器更改為“內部”，則無法通過調用應用程序來設置屬性，但它們仍然可見。 如何隱藏它們，使其不調用應用程序的請求模型實例？

Answer 1

public class BasicStudentInformation
{
    public int StudentId { get; set; }
}

public class StudentInformation : BasicStudentinformation
{
    public bool CanChangeBus { get; set; }
    public List<int> AvailableBuses { get; set; }
}

public class BusChangeRequestModel
{
    public BasicStudentInformation StudentInfo { get; set; }
    ...
    ...
}

public class BusChangeResponseModel
{
    public StudentInformation StudentInfo { get; set; }
    ...
}

Answer 2

使用繼承。 就像是：

public class StudentBase
{
    public int StudentId { get; set; }
}

public class StudentInformation : StudentBase
{
    public bool CanChangeBus { get; set; }
    public List<int> AvailableBuses { get; set; }
}

public class BusChangeRequestModel
{
    public StudentBase StudentInfo { get; set; }
    ...
    ...
}

public class BusChangeResponseModel
{
    public StudentInformation StudentInfo { get; set; }
    ...
}

Answer 3

因此，BusChangeRequest僅需要查看ID，然后僅應具有ID。

public class StudentInformation
{
    public int StudentId { get; set; }
    public bool CanChangeBus { get; set; }
    public List<int> AvailableBuses { get; set; }
}

public class BusChangeRequestModel
{
    public int StudentId { get; set; }
}

//I don't know what is expected as a repsonse?  Is StudentInfromation really the correct response
//or is something like "Accepted", "rejected", Fail...???
public class BusChangeResponseModel
{
    public StudentInformation StudentInfo { get; set; }
}
