这个项目的需求：SKYPE软件文字聊天同步翻译，并将翻译后的内容会发送给对方，将对方发给自己的话翻译成自己语种。功能见图：

这里发的话,SKYPE软件也会同步：

这个SKYPE小插件主要用到微软在线翻译api和SKYPE API，微软在线翻译参考使用文档 ，  skype api下载地址，执行文件夹里的reg.bat对此dll进行注册后，方可使用。Skype4COM.dll的引用请参考于小章的博客，接下来我将总结下这个小插件用到的一些知识点。

1.软件界面：

软件界面使用的是常用的DotNetBar破解的.dll类库的下载地址。

2.翻译接口的使用：

利用翻译接口进行翻译的功能制作成了一个WebService，因为考虑到翻译接口API里共用一个APP_ID，首先在自己的WS中引用微软在线翻译的web_service.

代码如下：

 public class WS_Translate : System.Web.Services.WebService
    {
        string appId = System.Configuration.ConfigurationManager.AppSettings["Application_id"];
        ServiceRefer.LanguageServiceClient client = new ServiceRefer.LanguageServiceClient();//微软在线翻译的web service
       
        [WebMethod(Discription="获取翻译结果<BR>参数：string text（要翻译的文本）, string from（该文本的语言代码）, string to（要翻译成的目标语言代码）<BR>返回：string （翻译后的文本）")]
        public string GetTranslateResult(string text,string from,string to)
        {                                
            string resulte=client .Translate (appId ,text ,from,to,"text/html","general");          
            return resulte;
        }      

        [WebMethod(Discription="返回语言代码<BR>参数：无<BR>返回：string[]")]
        public string[] GetLanguagesCode() { string[] LanguagesCode = client.GetLanguagesForTranslate(appId); return LanguagesCode; }

        [WebMethod(Discription="根据提供的显示语言类型，返回对应该语言的语言名称列表。<BR>参数：string localeLanguage<BR>返回：string[]")]
        public string[] GetLanguage() { string[] LanguagesName = client.GetLanguageNames(appId,"zh-CHS", GetLanguagesCode());//"zh-CHS"简体中文 
        return LanguagesName; } 
    }
