实现类似MVC ViewBag类型的对象

  public class ViewBag : DynamicObject {
        private readonly  Dictionary<string,dynamic> dic=new  Dictionary<string,dynamic>(); 
 
        public ViewBag() {
             
        }
        private Dictionary<string,dynamic> ViewData {
            get { 
                return dic;
            }
        } 
        public override IEnumerable<string> GetDynamicMemberNames() { 
            return ViewData.Keys;
        } 
 
        public override bool TryGetMember(GetMemberBinder binder, out object result) {
            result = ViewData[binder.Name]; 
            return true;
        }
 
        public override bool TrySetMember(SetMemberBinder binder, object value) {
            ViewData[binder.Name] = value; 
            return true;
        } 
    }

调用:

 dynamic viewBag = new ViewBag();
viewBag.Title="xxx";
Console.WriteLine(viewBag.Title);
