我有来自Google地理编码API的JSON blob，其中包含城市名称。我只是在寻找linq表达式来解决它。

这是我的标准： 给定“结果”中的“结果”，结果“类型”包含“地点” 为了得到结果，我希望'address_components'中的项目'types'包含'locality'
更新：
这很有效，但似乎可以更简洁：
if (responseObject["results"].Children().Count() > 0)
{
var postalResult = responseObject["results"].Children().FirstOrDefault((result) =>
{
return result["types"].Children().Contains("locality");
});
if(postalResult !=null)
{
var addressComponent = postalResult["address_components"].FirstOrDefault((ac) =>
{
return ac["types"].Children().Contains("locality");
});
if(addressComponent != null)
{
cityFromGoogle = addressComponent["long_name"].Value<string>().ToLower();
}
}
}
答案 0 :(得分：0)
如果你将你的json转换为具体的类，你可以轻松地处理它们
var resp = JsonConvert.DeserializeObject<Google.Response>(json);
var addresses = resp.results.Where(x => x.address_components.Any(a => a.types.Contains("locality")))
.ToList();
