Question

我有一些WebApi控制器，我想从中获取数据。我有各种各样的DTO，我想拥有一个能够处理所有DTO的功能。有办法吗？

我想要实现以下目标：

  public dynamic GetData(string ControllersName, dynamic DTOType)
        {         
            string Url = Settings.baseURLAddress + ControllersName;
            var request = (HttpWebRequest)HttpWebRequest.Create(Url);

                DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(List<DTOType>));
                var response = (List<DTOType>)serializer.ReadObject(request.GetResponse().GetResponseStream());
                return response;
        }

Answer 1

您是否尝试过使用泛型？

public List<T> GetData<T>(string ControllersName, T DTOType)
{         
     string Url = Settings.baseURLAddress + ControllersName;
     var request = (HttpWebRequest)HttpWebRequest.Create(Url);

     DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(List<T>));
     var response = (List<T>)serializer.ReadObject(request.GetResponse().GetResponseStream());
     return response;
}

您可以泛型

public List<T> GetData<T>(string ControllersName)
{         
     string Url = Settings.baseURLAddress + ControllersName;
     var request = (HttpWebRequest)HttpWebRequest.Create(Url);

     DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(List<T>));
     return (List<T>)serializer.ReadObject(request.GetResponse().GetResponseStream());
}

用法

var myList = GetData<SomeType>(someName);

泛型向.NET Framework引入了类型的概念参数，从而可以设计出以下类和方法将一种或多种类型的规范推迟到类或方法之前由客户端代码声明和实例化。
