官方的不一定是对的，机器最能证明一切
不知道从什么时候起，我们在写数据库连接，网络连接，文件操作时会习惯加上using，这种习惯被我们误称为一种模式，但事实上，一切事情都有因有果的，使用using的作用是什么？我想这个问题大家都知道应该，它可以释放资源，而对于数据库连接来说，它不是释放数据连接，而只是把连接放里“连接池”，等待下次使用时，直接用池子里取出来即可，好处当然就是省去了很多“建立连接”时的开销，而不对网络连接来说，则不是那么简单了，不能一同而义，这点对于ＭＳＤＮ也有错误的说法和写法，最近在看博文时（老外的，Infoq上翻译的）给出了有利的证据，具体看下文。
using的写法其实就是对IDispose模块的实现
using (var http = new HttpClient(handler))
{
http.Timeout = new TimeSpan(, , timeOut);
HttpResponseMessage response;
response = http.GetAsync(GeneratorUri(requestUri, ApiValidateHelper.GenerateCipherText(nv))).Result;
return response;
}
对于上面的代码，也是ＭＳＤＮ推荐的写法，即在使用完网络资源后，自动释放它，而对于下一次网络资源的访问，还需要从新去构建，事实上，从资源的销毁到下次资源的建立需要很大的代价，而且你的网络连接的构建（套接字）是有限制的，并不是无穷无近的，所以，我们必须要进行控制。

下面是大叔对using方式进行的测试，可以通过截图看到，我们的ＴＣＰ连接有很多，这样当高并发情况下，你的套接字连接将会被用斤。
