我想知道是否可以将抽象类的属性（或函数）值传递给实例类参数？还是我必须创建一个私有成员变量，为其分配数据并将其传递给实例类参数？这听起来令人困惑，因此下面的示例将有助于更好地阐明它。

看看“新的 DealerAccountRepository(MyEnvironmentSetting);” “DatabaseDataDealer”类中的部分。

public abstract class AEnvironmentSetting
{
    //Constructor...
    protected AEnvironmentSetting(EnvironmentSetting parmEnvironmentSetting)
    {
        _environmentSetting = new EnvironmentSetting
        {
            Emulation = parmEnvironmentSetting.Emulation, 
            Database = parmEnvironmentSetting.Database
        };
    }

    //Member variables...
    private EnvironmentSetting _environmentSetting = null;

    //Get/Set properties...
    protected string MyEmulation { get { return _environmentSetting.Emulation; } }  //No need for "set {}" property...
    protected string MyDatabase { get { return _environmentSetting.Database; } }  //No need for "set {}" property...

    //Functions...
    protected EnvironmentSetting MyEnvironmentSetting()
    {
        return _environmentSetting;
    }
}

public class DealerAccountRepository : AEnvironmentSetting
{
    //Constructor...
    public DealerAccountRepository(EnvironmentSetting parmEnvironmentSetting) : base(parmEnvironmentSetting)
    {
    }

    //Functions...
    public string Foo_Emulation()
    {
        return MyEmulation;  //This object coming from the abstract class "AEnvironmentSetting"...
    }
    public string Foo_Database()
    {
        return MyDatabase;  //This object coming from the abstract class "AEnvironmentSetting"...
    }
    public EnvironmentSetting Foo_EnvironmentSetting()
    {
        return MyEnvironmentSetting();  //This object coming from the abstract class "AEnvironmentSetting"...
    }
}

public class DatabaseDataDealer : AEnvironmentSetting
{
    //Constructor...
    public DatabaseDataDealer(EnvironmentSetting parmEnvironmentSetting) : base(parmEnvironmentSetting)
    {
    }

    //Get/Set properties...
    public DealerAccountRepository DealerAccount { get { return new DealerAccountRepository(MyEnvironmentSetting); } }  //No need for "set {}" property...

    //Functions...
    //N/A...
}

如果您问一个方法是否可以采用这样的抽象对象：

private void DoSomething(AEnvironmentSetting a)

那么是的，它可以，并且您可以使用抽象类中的每个属性和方法，包括调用抽象方法。但是，无论谁调用此方法，都必须发送一个 cals 的实例，继承抽象类，如下所示：

DatabaseDataDealer d = new DatabaseDataDealer ();
DoSomething(d);

如果将调用抽象方法，则将调用的DoSomething实现DatabaseDataDealer

在构造函数中，您可以调用基础，然后您将进入抽象构造函数。最后让我说学习这个的最好方法就是尝试。编译并运行您的代码并设置一个断点以查看它是如何进行的以及通过哪些步骤
