假设有以下C#类定义和代码:
public class BaseClass
{
public virtual void MyMethod()
{
...do something...
}
}
public class A : BaseClass
{
public override void MyMethod()
{
...do something different...
}
}
public class B : BaseClass
{
public override void MyMethod()
{
...do something different...
}
}
public class AnotherObject
{
public AnotherObject(BaseClass someObject)
{
someObject.MyMethod(); //This calls the BaseClass method, unfortunately.
}
}
假设传入的对象是A或B的实例,我想调用实际上在A或B中找到的MyMethod()
,而不是在BaseClass
中找到的。除了这样做:
public class AnotherObject
{
public AnotherObject(BaseClass someObject)
{
A temp1 = someObject as A;
if (A != null)
{
A.MyMethod();
}
B temp2 = someObject as B;
if (B != null)
{
B.MyMethod();
}
}
}
我该怎么做?
