项目需要实现一个计时的功能,利用Chronometer虽然可以很方便的实现计时功能,但需要的却是一个倒计时控件. 百度了一下方法不少，倒计时的却没有，于是用Chronometer封装了一个倒计时的类,本着开源的精神，分享给大家！

OSS.Http项目对于.Net Standard标准库的支持已经迁移完毕，OSS开源系列两个最底层的类库已经具备跨运行时支持的能力。由于OSS.Http类库是几年前我参照RestSharp的思路，完成的一个轻量型Http请求框架。因为时间较久底层使用的还是HttpWebRequest，这次基本上是完全重构，这篇文章主要包含 1. HttpClient的介绍，2. 重构的思路， 3. 容易遇到的问题。 一. httpclient的基本介绍 HttpClient应该是在.net framework4.5版本左右引用的新功能，在此之前常用的是HttpWebRequest，相比较而言，前者更加的简单
