Question

我现在一直在寻找能够将任何语言翻译成另一种语言的代码，但我发现的代码都没有。我知道谷歌有一个很好的翻译API，但我不能让任何人的Delphi代码工作始终存在错误。任何帮助将不胜感激，我需要一个程序，可以尽快翻译我最后的学校项目。

Answer 1

Google Translate API是个不错的选择，但现在只能作为付费服务使用。您可以尝试使用Microsoft Translator V2 API，查看本文Using the Microsoft Translator V2 API from delphi，了解有关如何在delphi中使用此API的更多详细信息。

<强>更新这是修改为与您的delphi版本兼容的文章的相同演示项目。

Answer 2

也许你没有找到Marco Cantu的作品？Works with REST/AJAX/Delphi

但正如RRUZ所说，Google Translate API现在仅作为付费服务提供。

Answer 3

首先，您找不到100％的工具来从一种语言翻译成另一种语言。你可以拥有一个为你做一些（或多或少）工作的工具，但你需要“抛光”其余部分。正如RRUZ所说，你可以使用微软的翻译，但我所说的也适用于这种情况。任何此类工具都会花费你的钱。谷歌的翻译非常好，但你需要付钱。

PS：我不认为在学校他们会要求你创建一个从任何语言翻译成任何语言的工具。也许一个小工具可以证明你有这个概念。只是我的2美分......
