原文:Net Core 实现谷歌翻译ApI 免费版
由于谷歌翻译官方API是付费版本，本着免费和开源的精神。分享一下用 Net Core 实现谷歌翻译API的代码。
项目引用的Nuget 包：
ChakraCore.NET
Newtonsoft.Json
JavaScriptEngineSwitcher.ChakraCore.Native.win-x86(特别说明一下"win-x86",代表程序运行环境。)
翻译地址：https://translate.google.cn (国内可以访问)
参数说明：
text：待翻译文本
sl：需要翻译的语言(中文：zh-CN，英文：en)
tl： 翻译结果的语言(中文：zh-CN，英文：en)
