我一直在努力让 C# 的 Wolframalpha API 无济于事。我一直在尝试使用这两个资源:
帖子中的答案是半有用的，但我无法编译任何东西。我是 C# 的新手，所以有点不知所措。我真的很难尝试让它接受输入然后输出结果。
如果有人可以帮助我使此代码正常工作，以便我可以使用有效示例，或者知道我可以从中建模的示例项目，我们将不胜感激。
这是我剪切并粘贴到 C# (Visual Studio) 控制台项目中的代码:

最佳答案
这个 codeplex 项目声称涵盖了最新的 Wolfram Alpha API 并包括一个示例: http://wolframalphaapi20.codeplex.com/
控制台应用程序使用静态 Main 方法作为它们的入口点。此例程通常可以在文件 program.cs 中找到，该文件是在为控制台应用程序创建新项目时自动创建的。
如果编译器说找不到 Main，那么它可能已被删除或从未创建。很难说没有任何代码可以看。当 Main 方法的问题得到解决时，可能会显示更多错误。
关于C# Wolfram alpha API 工作示例，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10778954/
