C#在类外部实现对私有字段的值的修改

1 class RefHero
2 {
3     string name = "Tom";
4     int age = 10;
5     bool isBoy = false;
6 }

 1 static void ModifyRefHeroFiled()
 2 {
 3     //收集需要修改的私有字段的名字
 4     string Filed_name = "name";
 5     string Filed_age = "age";
 6     string Filed_isBoy = "isBoy";

 8     Type type = typeof(RefHero);
 9     RefHero hero = new RefHero();
10     //获取 RefHero 中所有的实例私有字段
11     FieldInfo[] fieldArray = type.GetFields(BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.DeclaredOnly);
12     foreach (FieldInfo filed in fieldArray)
13     {
14         string fileName = filed.Name;
15         if (Filed_name == fileName)
16             filed.SetValue(hero, "Jick");
17         else if (Filed_age == fileName)
18             filed.SetValue(hero, 18);
19         else if (Filed_isBoy == fileName)
20             filed.SetValue(hero, true);
21         Console.WriteLine(string.Format("字段名字:{0} 字段类型:{1} 值 = {2}", filed.Name, filed.MemberType, filed.GetValue(hero)));
