如何从WCF HTTP服务返回动态列表

Question

  public List<dynamic> GetDynamicResult()
        {
            List<dynamic> lstDynamic = new List<dynamic>();
            lstDynamic.Add(new { ID = "1", Name = "ABC" });
            lstDynamic.Add(new { ID = "1", Name = "XYZ" });
            return lstDynamic;
        }

当我将列表从WCF返回到ASP.NET Web App时使用 List<dynamic> lstDynamic = objClient.GetDynamicResult(); 我收到此错误：The underlying connection was closed: The connection was closed unexpectedly

WCF需要定义通过有线发送的DataContract（使用序列化）。使用动态类型与此冲突。您可以使用字符串组合与（反）序列化。
