C# 字符串訪問屬性

//1.公開字段的實現
public class Foo{
    public float aa=100;
    public void test(){
        this["aa"]=300;
    }
    public float this[string name]{
        get{
            return (float)GetType().GetField(name).GetValue(this);
        }
        set{
            GetType().GetField(name).SetValue(this,value);
        }
    }
}
//2.私有屬性的實現
public class Foo{
    private float m_aa=100;
    public float aa{ get=>m_aa; set=>m_aa=value;}
    public void test(){
        this["aa"]=300;
    }
    public float this[string name]{
        get{
            return (float)GetType().GetProperty(name).GetValue(this);
        }
        set{
            GetType().GetProperty(name).SetValue(this,value);
        }
    }
}

var v=new Vector2(10,20);
Debug.Log(v.GetType().GetField("x").GetValue(v));//output:10
Debug.Log(v.GetType().GetField("y").GetValue(v));//output:20

var foo=new Foo();
Debug.Log(foo["aa"]);//output:100
foo["aa"]=200;
Debug.Log(foo["aa"]);//output:200
foo.test();
Debug.Log(foo["aa"]);//output:300
