C#动态添加属性

class DynamicInputParams: DynamicObject
    {
        Dictionary<string, object> property = new Dictionary<string, object>();
                

        public override bool TryGetMember(GetMemberBinder binder, out object result)
        {
            string name = binder.Name;
            return property.TryGetValue(name, out result);
        }
                
        public override bool TrySetMember(SetMemberBinder binder, object value)
        {            
            property[binder.Name] = value;
            return true;
        }
    }

首先继承DynamicObject，添加property属性，并实现下面的两个方法，然后调用方法如下：

dynamic  dyInputParams = new DynamicInputParams();

            dyInputParams.A = "abc";
            dyInputParams.B = "d";

            var s = dyInputParams.A;

s的值为“abc”

但是该属性没有get/set方法，所以在PropertyGrid控件中无法显示该属性。
