[英]How to convert an abstract base class to generic derived class and access properties of the child class?
I have my class hierarchy as follows: 我的班级层次结构如下:
[DataContract]
[Serializable]
[KnownType(typeof(ChildClass2<>))]
public abstract class BaseClass
{
protected BaseClass(string property1)
{
this.Property1 = property1;
}
[DataMember]
public string Property1 { get; private set; }
public abstract bool Method1(string inputValue);
}
[DataContract]
[Serializable]
public abstract class ChildClass1<T> : BaseClass
{
protected ChildClass1(string property1, T property2) : base(property1)
{
this.Property2 = property2;
}
[DataMember]
public T Property2 { get; private set; }
}
[DataContract]
[Serializable]
public class ChildClass2<T> : ChildClass1<T>
{
public ChildClass2(string proprty1, T property2)
: base(property1, property2)
{
}
public override bool Method1(string inputValue)
{
// Some processing....
}
}
Now I am instantiating ChildClass2 as baseClass type like below: 现在,我将ChildClass2实例化为baseClass类型,如下所示:
BaseClass baseClass = ChildClass2<string>("test1", "test2");
How can I cast baseClass to ChildClass2 type so I can access baseClass.Property2? 如何将baseClass强制转换为ChildClass2类型,以便可以访问baseClass.Property2?
I tried something like (ChildClass2)baseClass.Property2 does not work. 我尝试了类似(ChildClass2)baseClass.Property2的操作。
BaseClass baseClass = ChildClass2<string>("test1", "test2");
string value = ((ChildClass2<string>) baseClass).Property2;
