class TypeA
{
public TypeA Copy () { ... }
public bool IsEqual(TypeA mytypeA) { ... }
public bool IsSame(TypeA mytypeA) { ... }
...
}
class TypeACollection : List<TypeA>
{
public bool IsSame (TypeACollection typeAs)
{
if (Count != typeAs.Count)
return false;
return this[0].IsSame(typeAs[0]);
}
...
}
TypeB,TypeC具有类似的功能Copy / IsEqual / IsSame作为TypeA。 TypeBCollection,TypeACollection具有类似的IsSame。例外是TypeBCollection使用TypeB.IsSame,TypeCCollection使用TypeC.IsSame。
现在,我计划添加2个新类:LocData和LocDataCollection
class LocData
{
public virtual TypeA Copy () { ... }
public virtual bool IsEqual(TypeA mytypeA) { ... }
public virtual bool IsSame(TypeA mytypeA) { ... }
...
}
class LocDataCollection<T> : List<LocData> where T: LocData
{
public bool IsSame (LocDataCollection<T> typeAs)
{
if (Count != typeAs.Count)
return false;
return this[0].IsSame(typeAs[0]);
}
...
}
并重写现有代码,
class TypeA : LocData
{
public new TypeA Copy () { ... }
public new bool IsEqual(TypeA mytypeA) { ... }
public new bool IsSame(TypeA mytypeA) { ... }
...
}
class TypeACollection : ???
{
???
// so I can remove IsSame here,
// when I call IsSame, it will use one from LocDataCollection and still call
// TypeA.IsSame
...
}
现在我迷失在抽象/虚拟/通用/ ......中,这是最好的方法吗?
答案 0 :(得分:1)
您应该将new
替换为overrides
,然后创建LocDataCollection<T> : Collection<T> where T : LocData
。
