问题描述
检查下面请了code:
check the code below please:
static void Main(string[] args) {
IList<dynamic> items = new List<dynamic>();
items.Add(3);
items.Add("solid");
dynamic i = new ExpandoObject();
items.Add(i); //System.Collections.Generic.IList<object>' does not contain a definition for 'Add'
Console.WriteLine();
}
这是在动态机制中的错误?
is this a bug in "dynamic" mechanism?
