我正在开发一种用于学习目的的工具，它使用 google apis 执行搜索。使用 HTTPSocket 我以 json 格式获取搜索结果，然后使用 CharcoalDesign.co.uk 编写的 json.parser 将其解析为字典

这是 json 结果的样子：

{"responseData": {
 "results": [
  {
   "GsearchResultClass": "GwebSearch",
   "unescapedUrl": "http://en.wikipedia.org/wiki/Paris_Hilton",
   "url": "http://en.wikipedia.org/wiki/Paris_Hilton",
   "visibleUrl": "en.wikipedia.org",
   "cacheUrl": "http://www.google.com/search?q\u003dcache:TwrPfhd22hYJ:en.wikipedia.org",
   "title": "\u003cb\u003eParis Hilton\u003c/b\u003e - Wikipedia, the free encyclopedia",
   "titleNoFormatting": "Paris Hilton - Wikipedia, the free encyclopedia",
   "content": "\[1\] In 2006, she released her debut album..."
  },
  {
   "GsearchResultClass": "GwebSearch",
   "unescapedUrl": "http://www.imdb.com/name/nm0385296/",
   "url": "http://www.imdb.com/name/nm0385296/",
   "visibleUrl": "www.imdb.com",
   "cacheUrl": "http://www.google.com/search?q\u003dcache:1i34KkqnsooJ:www.imdb.com",
   "title": "\u003cb\u003eParis Hilton\u003c/b\u003e",
   "titleNoFormatting": "Paris Hilton",
   "content": "Self: Zoolander. Socialite \u003cb\u003eParis Hilton\u003c/b\u003e..."
  },
  ...
 ],
 "cursor": {
  "pages": [
   { "start": "0", "label": 1 },
   { "start": "4", "label": 2 },
   { "start": "8", "label": 3 },
   { "start": "12","label": 4 }
  ],
  "estimatedResultCount": "59600000",
  "currentPageIndex": 0,
  "moreResultsUrl": "http://www.google.com/search?oe\u003dutf8\u0026ie\u003dutf8..."
 }
}
, "responseDetails": null, "responseStatus": 200}

我想循环“结果”的每个值并将数据添加到列表框，而不添加任何其他响应数据（例如“光标”）的问题。

Dim d as Dictionary
Dim c as Collection 

data = Json.parse(content) // use the class json.parse
d = data.Value("responseData")
c = d.Value("results")

在那之后，我不知道如何循环每个“结果”值，我尝试了很多方法 for-each ... 与字典一起使用，“对于 d.Keys() 中的每个键”，但不适用于集合。我哪里错了？

要遍历集合，您需要通过 Items 函数访问它。

for i as integer = 1 to c.count //Collection is 1 based
   dim s as string
   s = c.item(i)
next
