请问博客园的高手们！怎么实现MVC中的UpdataModel功能，在WEBFROM中！

这是我一前的做法:

        //自动获取Form中的值 from Name
        public static T GetPost<T>(this NameValueCollection form)
        {
            Type type = typeof(T);
            T objResult = Activator.CreateInstance<T>();
            PropertyInfo[] pi = type.GetProperties();

            pi.ToList().ForEach(O =>
            {
                if (form[O.Name] != null)
                {
                    try
                    {
                        var isNullable = O.PropertyType.ToString().Contains("System.Nullable");
                        if (isNullable)
                        {
                            if (O.PropertyType.FullName.Contains("System.Int32"))
                            {
                                O.SetValue(objResult, int.Parse(form[O.Name]), null);
                            }

                            if (O.PropertyType.FullName.Contains("System.DateTime"))
                            {
                                O.SetValue(objResult, DateTime.Parse(form[O.Name]), null);
                            }
                        }

                        O.SetValue(objResult, Convert.ChangeType(form[O.Name], O.PropertyType), null);
                    }
                    catch
                    {
                    }
                }

            });
            return objResult;
        }

总是觉得不太好！而且还有BUG，请问博客园的诸位高手你们是怎么做的？
