C#Reflection - 从一个简单的类中获取字段值

using System;
using System.Reflection;

class MyClass
{
    public string MyField = "Hello, Reflection!";
}

class Program
{
    static void Main(string[] args)
    {
        MyClass obj = new MyClass();
        Type type = obj.GetType();
        FieldInfo fieldInfo = type.GetField("MyField");
        string fieldValue = (string)fieldInfo.GetValue(obj);
        Console.WriteLine("MyField的值是：" + fieldValue);
    }
}
