Visual Studio / Resharper Extract Interface to break god object

Question

我正在尝试将一个大对象分解成更小的界面。示例：

public class SomeService
{
    readonly GodObject _god; // <-- Replace this with an Interface

    public SomeService(GodObject god)
    {
        _god = god;
    }

    public string SomeProperty => _god.GetSomeValue();
    public string SomethingElse => _god.SomethingDifferent;
}

public class GodObject
{
    public string GetSomeValue()
    {
        // do something and return
    }
    public string SomethingDifferent { get; set; }

    // Lots and lots more Members
}

重构后它应该看起来像这样：

public interface IPartialGodObject // <-- Extracted from GodObject
{
    string GetSomeValue();
    string SomethingDifferent { get; }
}

public class SomeService
{
    readonly IPartialGodObject _god; // <-- Now only references the Interface

    public SomeService(IPartialGodObject god)
    {
        _god = god;
    }

    public string SomeProperty => _god.GetSomeValue();
    public string SomethingElse => _god.SomethingDifferent;
}

public class GodObject : IPartialGodObject
{
    //...
}

Visual Studio 或 Resharper 是否能够自动执行此类操作？我确实知道 Extract Interface，但是对于一个大对象来说，从一个大列表中只检查几个 Properties/Methods 是非常痛苦的。

Update：澄清一下，我只想提取 SomeService class.

使用的成员

Answer 1

似乎没有自动化流程可以执行此操作。我最终做的是以下 (Resharper 2018):

1. Extract Interface
2. Select Public
3. 用新界面替换了有问题的成员
4. 进入界面，依靠Resharper的"Property is never used"删除所有不用的属性
