C#:通过反射访问继承的私有实例成员

using System;
using System.Reflection;

class BaseClass
{
    private int _privateInt = 5;
}

class DerivedClass : BaseClass
{
    public void AccessPrivateInt()
    {
        Type baseType = typeof(BaseClass);
        FieldInfo fieldInfo = baseType.GetField("_privateInt", BindingFlags.NonPublic | BindingFlags.Instance);
        int value = (int)fieldInfo.GetValue(this);
        Console.WriteLine("Value of _privateInt: " + value);
    }
}

class Program
{
    static void Main(string[] args)
    {
        DerivedClass derived = new DerivedClass();
        derived.AccessPrivateInt();
    }
}
