关于.net：C＃依赖注入示例

C# Dependency Injection Sample

我想知道在处理依赖项注入时让对象从实现接口的类继承是否有意义例子

public interface IPeople
{
string Name { get; set; }
int Age { get; set; }
string LastName { get; set; }

}

public class CPeople : IPeople
{..implemented IPeople Methods..}

这样我只需要在一个地方实现接口。我只是不确定这是否会被认为是一个很糟糕的结合。

m_Parent = new Parents(objMom,objDad);

}
public override string ToString()
{
return m_Parent.Mom.Name +"" + m_Parent.Mom.LastName + " is" + m_Parent.Mom.Age +" years of age," + m_Parent.Dad.Name +"" + m_Parent.Dad.LastName +" aged" + m_Parent.Dad.Age.ToString();
}
