我正在尝试从 Google AJAX 搜索 API 解析一些 JSON 数据。我有这个 URL，我想把它分解，以便显示结果。我目前已经编写了这段代码，但是对于下一步该做什么我很迷茫，尽管那里有许多带有简化 JSON 字符串的示例。
一般来说，作为 C# 和 .NET 的新手，我一直在努力为我的 ASP.NET 页面获得真正的文本输出，因此建议我尝试 JSON.NET。谁能指出我正确的方向，只需编写一些从 Google AJAX 搜索 API 接收 JSON 并将其打印到屏幕上的代码？
编辑：全部修复！所有结果都运行良好。再次感谢 Dreas Grech！

该代码当前可以完美编译和运行，但没有返回任何结果。有人可以帮我返回我需要的东西，准备好打印到屏幕上的结果吗？
编辑：
Json.NET 使用与上述示例相同的 JSON 和类工作。
GoogleSearchResults g1 = JsonConvert.DeserializeObject<GoogleSearchResults>(json);
