Error CS1061: 'HttpWebRequest'

2017.07.23

错误信息：

Program.cs(26,66): error CS1061: 'HttpWebRequest'does not contain a definition for 'GetResponse' and no extension method'GetResponse' accepting a first argument of type 'HttpWebRequest' could befound

(are you missing a using directive or anassembly reference?)

解决方法：

因为版本更新问题，错误原因是：没有request.GetResponse()方法；修改成request.GetResponseAsync().Result；即可。或者修改同步异步访问设置，优化性能。
