我如何序列化有一个接口作为属性的对象？ [英] How can I serialize an object that has an interface as a property?

问题描述

我有2个接口，IA和IB。

I have 2 interfaces IA and IB.

public interface IA
{
    IB InterfaceB { get; set;  }
}

public interface IB
{
    IA InterfaceA { get; set;  }

    void SetIA(IA value);
}

每个接口引用等。

我想序列化ClassA的定义如下：

I am trying to serialize ClassA as defined below.

[Serializable]
public class ClassA : IA
{
    public IB InterfaceB { get; set; }

    public ClassA()
    {
        // Call outside function to get Interface B
        IB interfaceB = Program.GetInsanceForIB();

        // Set IB to have A
        interfaceB.SetIA(this);
    }
}

[Serializable]
public class ClassB : IB
{
    public IA InterfaceA { get; set; }

    public void SetIA(IA value)
    {
        this.InterfaceA = value as ClassA;
    }
}

我得到一个错误，当我尝试过序列化，因为2属性界面。我想序列化的属性。

I get an error when I try too serialize because the 2 properties are interfaces. I want to serialize the properties.

我将如何解决此得到什么？

How would I get around this?

我需要在引用每个接口到另一个。我需要能够序列化类来回。

I need to have references in each interface to the other. And I need to be able to serialize the class back and forth.

推荐答案

您在你的代码的各种错误，否则这会工作得很好。

You have various bugs in your code, otherwise this would work just fine.

1. 在构造 ClassA的，你要设置的地方变量IB，而不是对象的IB对象。


2. 在 ClassB的，你是铸造回对象具体类，而不是把的单独的接口类型

1. In the constructor for ClassA, your are setting an local variable IB, not the object's IB object.
2. In ClassB, you are casting back to the object concrete class, instead of leaving it alone as the interface type.

下面是你的代码应该是什么样子：

Here is what your code should look like:

public interface IA 
{ 
    IB InterfaceB { get; set; } 
}

public interface IB 
{ 
    IA InterfaceA { get; set; } 
    void SetIA(IA value);
}

[Serializable]
public class ClassA : IA
{    
    public IB InterfaceB { get; set; }    

    public ClassA()    
    {        
        // Call outside function to get Interface B        
        this.InterfaceB = new ClassB();

        // Set IB to have A        
        InterfaceB.SetIA(this);    
    }
}

[Serializable]
public class ClassB : IB
{    
    public IA InterfaceA { get; set; }    

    public void SetIA(IA value)    
    {       
        this.InterfaceA = value;    
    }
}

[STAThread]
static void Main()
{
    MemoryStream ms = new MemoryStream();
    BinaryFormatter bin = new BinaryFormatter();

    ClassA myA = new ClassA();

    bin.Serialize(ms, myA);

    ms.Position = 0;

    ClassA myOtherA = bin.Deserialize(ms) as ClassA;


    Console.ReadLine();
}
