dynamic这个动态类型早在.net3.5时就已经出现了,当时是伴随的Linq一起让我们认识的,但在使用时总觉得有点别扭,因为它是internal的,所以不能跨程序集使用,这对于分层开发的我们来说显然是不能接受的,所以把dynamic了冷落了很久,应该说是5年吧,哈哈,这几天在睡觉时,突然有个想法,最近在开发SOA时,为了使客户端与服务端有类对应关系,进行序列化,所以总要定义一些DTO,当然你可以把服务端和客户端都引用这个DTO,或者在客户端手动写一个也行,但感觉这两种方式在程序解耦上都不完美,这时我就想起了dynamic,我在序列化时,可不可以用它做中间类型呢?
经过今天的测试,答案是“可以”,这是让我很兴奋的,呵呵
测试代码:
var url = "http://localhost:24334/api/UserApi";
var handler = new HttpClientHandler() { AutomaticDecompression = DecompressionMethods.GZip };
using (var http = new HttpClient(handler))
{
//await异步等待回应
var response = http.GetAsync(url); //将服务端返回的实体序列化为dynamic动态类
var obj = JsonConvert.DeserializeObject<dynamic>(response.Result.Content.ReadAsStringAsync().Result); //遍历这个动态集合
foreach (var item in obj)
{
return Content("userName:" + item.UserName);
}
}
结果代码:
