我下载GoogleTranslateAPI.dll文件，并添加它的引用到我的项目。 现在，我参加了一个文本框，并写下约翰在里面，并采取了标签，并希望这样写：约翰的，但在法国的语言。所以我写了button_click事件......

I download the GoogleTranslateAPI.dll file and added the reference of it to my project. Now i took a textbox and wrote 'John' in it and took a label and want to be written 'John' in it but in 'French' language. So i wrote in the button_click event....

    private void button1_Click(object sender, EventArgs e)
    {
        string TT = Txt1.Text;

        Label1.Text=Google.API.Translate.Translator.Translate(TT, Google.API.Translate.Language.English,Google.API.Translate.Language.French);
    }

这给出了一个错误说翻译失败......谁能告诉我做错了什么？ 这是一个桌面应用程序，并运行脱线。

This gives an error saying "TRANSLATE FAILED"... Can anyone tell what i did wrong ?? This is a desktop application and will run off line.
