在运行时生成接口实现 [英] Generating interface implementation at runtime

问题描述

我想问一下是否有一个库，该库可以在运行时生成接口的实现，并具有以下所示的一些其他功能。

I would like to ask is there a library which allows to generate implementation of interface at runtime with some additional features illustrated below.

假设我有这样的接口：

interface ICustomer
{
    string Name {get;set;}
    string IAddress { get;set; }
}

interface IAddress
{
    string Street {get;set;}
}

我想做这样的事情：

ICustomer customer = someLibrary.Create<ICustomer>(bool createSubObjects)

其中 Create< ; T>（）方法将在运行时创建这样的实现：

where Create<T>() method would create an implementation like this at runtime:

class RuntimeCustomer : NotifyPropertyChanged,ICustomer 
//NotifyPropertyChanged would be hand written class
{
    string name;
    IAddress address = new RuntimeAddress(); 
    //if createSubObjects == false then `IAddress address = null`

    public string Name 
    {
       get { return name; }
       set { SetProperty(ref name, value); }
    }
    public IAddress Address
    { 
       get { return address; }
       set { SetProperty(ref address, value) }
    }
}

class RuntimeAddress : NotifyPropertyChanged, IAddress
{
    string street;
    public string Street 
    {
        get { return street; }
        set { SetProperty(ref,street, value) }
    }
}

请问有什么想法吗？

推荐答案

如法律上所说的，您可以为此使用DynamicProxy，但这将是适用的方面到界面的JIT实现。请查看以下内容： http：//jonas.follesoe。 no / 2009/12/23 / automatic-inotifypropertychanged-using-dynamic-proxy /

as jure said you can use DynamicProxy for this, but it would be aspects applied to a JIT'ed implementation of your interfaces. Check this out: http://jonas.follesoe.no/2009/12/23/automatic-inotifypropertychanged-using-dynamic-proxy/

PostSharp在此用例上也很出色，但这是由编译时编织与运行时JIT'ing。 http://www.postsharp.net/aspects/examples/inotifypropertychanged

PostSharp excels at this use case as well, but it's done by compile-time weaving vs. runtime JIT'ing. http://www.postsharp.net/aspects/examples/inotifypropertychanged
