都可以改变外部变量的值 void jiafa(int a, int b, ref int c) { c = a + b; } // Start is called before the first frame update void Start() { //ref修饰的必须在外面赋值 int res=0; jiafa(1, 2,ref res); print(res); } void jiafa(int a, int b, out int c) { c = a + b; } // Start is called before the first frame update void Start() { //out修饰的不用在外面赋值 int res; jiafa(1, 2, out res); print(res); }
常见泛型约束如下1.值类型 where 泛型字母:struct 2.引用类型 where 泛型字母:class 必须是引用类型 3.存在无参公共构造函数 where 泛型字母:new() 4.某个类本身或者其派生类 where 泛型字母:类名 5.某个接口的派生类型 where 泛型字母:接口名 6.另一个泛型类型本身或者派生类型 where 泛型字母:另一个泛型字母
