    }

我想要得到的對象的列表，每個對象將包含的StreetAddress，估計，城市等的價值..

那麼如何通過名稱訪問這些元素？

您的評論被標記爲「C＃」，但是您沒有說出使用哪個.NET庫來解析JSON。 –

喬懷特所說的背馱式，你有沒有建立你的對象序列化成？ –

那麼看着你的JSON輸入（並假設您正在使用您的代碼表示C＃），也提供了，我明白你的問題是正確的。你可以做到以下幾點：

創建一些對象，你可以映射到，在VS2012 Update 2可以複製，你在你的問題中提供的JSON - >打開cs文件 - >右鍵 - >粘貼特殊 - >「粘貼JSON作爲類」，這將產生如下：

public class Rootobject 
{ 
    public Responseheader responseHeader { get; set; } 
    public Response  response  { get; set; } 
} 

public class Responseheader 
{ 
    public int status { get; set; } 
    public int QTime { get; set; } 
    public Params _params { get; set; } 
} 

public class Params 
{ 
    public string q { get; set; } 
    public string wt { get; set; } 
    public string fq { get; set; } 
} 

public class Response 
{ 
    public int numFound { get; set; } 
    public int start { get; set; } 
    public Doc[] docs  { get; set; } 
} 

public class Doc 
{ 
    public string streetAddress { get; set; } 
    public float estimate  { get; set; } 
    public string city   { get; set; } 
    // etc ... 
}

那麼你可以使用Json.NET（你也可以從NuGet得到）的輸入反序列化到一個適當的C＃對象，如這個：

Rootobject rootObject = JsonConvert.DeserializeObject<Rootobject>(jsonInput);

當然，您現在可以訪問任何它的性能，如 - >rootObject.response.docs等

我希望這有助於。
