关于 C# 中的 isOverrided

Question

如何区分派生的class是否实现了方法的重写？

class BaseClass
{
    public virtual void targetMethod() { return; }
}

class DerivedClass:BaseClass
{
    public bool isOverrideTargetMethod()
    {
        //Here, I wants to judge whether DerivedClass is overrided targetMethod.
     }
     public override void targetMethod()
     {
         base.targetMethod();
     }
}

首先，从设计的角度来看，您尝试做的事情不是很好，但如果您真的想做，反思就是答案。

using System.Reflection;

Type classType = typeof(DerivedClass);
MethodInfo method = classType.GetMethod("targetMethod");
if (method.DeclaringType == typeof(BaseClass))
    Console.WriteLine("targetMethod not overridden.");
else
Console.WriteLine("targetMethod is overridden " + method.DeclaringType.Name);
