OSMeteorTranslationAPI（百度，有道）对比

今天做翻译的时候分别用百度和有道的api做了对比

首先声明一下，百度和有道的APIKEY需要自己去申请

界面：

代码：

private void btn_translation_Click(object sender, EventArgs e)
        {
            //string baiduKey = "aMkc5Tcs2sGoTM56XGL1FlQc";

            // string rs = BaiduTans_Get(baiduKey, this.richTxt_src.Text, "zh", "en");
           if(!NetworkIsCoon())

        }

各种API地址：包括有道、百度： http://blog.csdn.net/osmeteor/article/details/17023559

结论：

在使用百度API的时候最好不要使用自动 ，比如百度APi：在英文翻译成中文的时候自动翻译的时候会这样

所以还是别偷懒：尽量别用aoto。

但是对有道API处理的时候：这个理对中文翻译成英文的是换行没有出来很好，

我们在看看有道怎么处理换行的 ，这里是有道返回的结果

但是我用有道在线翻译的时候又是正常的，可能我不了解内部转换算法吧

希望有这方面研究的同学看到之后能给予指点。。。

也希望百度和有道提供更好的翻译API。。。
