使用Type类以前需要引用反射的命名空间：

using System.Reflection;

以下是完整代码：

public class ReflectionDemo : MonoBehaviour
{void Start(){A a = new A();B b = new B();A[] abArray=new A[] { a, b };foreach(A v in abArray){Type t = v.GetType();Debug.Log("Object type : " + t.Name);FieldInfo[] fi = t.GetFields();foreach(FieldInfo f in fi){Debug.Log("Field : " + f.Name);}}}
}class A
{public int AField = 0;
}class B : A
{public int BField = 0;
}

输出结果：
