1、ExpandoObject
1 dynamic expObj = new ExpandoObject(); 2 expObj.FirstName = "Daffy"; 3 expObj.LastName = "Duck"; 4 Console.WriteLine(expObj.FirstName + " " + expObj.LastName); 5 Func<DateTime, string> GetTomorrow = today => today.AddDays(1).ToShortDateString(); 6 expObj.GetTomorrowDate = GetTomorrow; 7 Console.WriteLine("Tomorrow is {0}", expObj.GetTomorrowDate(DateTime.Now)); 8 9 expObj.Friends = new List<Person>(); 10 expObj.Friends.Add(new Person() { FirstName = "Bob", LastName = "Jones" }); 11 expObj.Friends.Add(new Person() { FirstName = "Robert", LastName = "Jones" }); 12 expObj.Friends.Add(new Person() { FirstName = "Bobby", LastName = "Jones" }); 13 14 foreach (Person friend in expObj.Friends) 15 { 16 Console.WriteLine(friend.FirstName + " " + friend.LastName); 17 }
2、DynamicObject
1 class CusDynamicObject : DynamicObject 2 { 3 Dictionary<string, object> _dynamicData = http://www.mamicode.com/new Dictionary<string, object>(); 4 5 public override bool TryGetMember(GetMemberBinder binder, out object result) 6 { 7 bool success = false; 8 result = null; 9 if (_dynamicData.ContainsKey(binder.Name)) 10 { 11 result = _dynamicData[binder.Name]; 12 success = true; 13 } 14 else 15 result = "Property Not Found!"; 16 17 return success; 18 } 19 20 public override bool TrySetMember(SetMemberBinder binder, object value) 21 { 22 _dynamicData[binder.Name] = value; 23 return true; 24 } 25 26 public override bool TryInvokeMember(InvokeMemberBinder binder, object[] args, out object result) 27 { 28 dynamic method = _dynamicData[binder.Name]; 29 result = method((DateTime)args[0]); 30 return result != null; 31 } 32 33 }
