使用反射设置通用属性的值

Question

我希望以动态方式设置 Unit 类的 SyncVar 属性的 .Value 属性。以下内容无法编译，我不想硬编码SynvVar<int>，因为它可能是许多基本类型<int>、<string>、<bool> 等。

class SyncVar<T>
    {
        public T Value { get; set; }
    }

    class Unit
    {
        public SyncVar<int> Health { get; set; } = new SyncVar<int>();
    }

    class Program
    {
        static void Main(string[] args)
        {
            Unit unit = new Unit();
            unit.Health.Value = 100;

            var prop = unit.GetType().GetProperty("Health").GetValue(unit);

            // compile error as prop object doesn't contain .Value
            // I need to dynamically figure out what type was used in this generic property so I can cast to that and set it's value
            prop.Value = 50;
        }
    }

Answer 1

如果任意T你可以尝试Reflection一次：

      prop.GetType().GetProperty("Value").SetValue(prop, 50);
