我有一個 JSON 呼叫，這給我帶來了一個帶有四個陣列的物件。
HttpWebRequest apiRequest = WebRequest.Create(url) as HttpWebRequest;
string apiResponse = "";
using (HttpWebResponse response = apiRequest.GetResponse() as HttpWebResponse)
{
StreamReader reader = new StreamReader(response.GetResponseStream());
apiResponse = reader.ReadToEnd();
}
var dict = new JavaScriptSerializer().Deserialize<Dictionary<string, object>>(apiResponse);
var results = dict["results"];
然后我var dict用來存盤這四個陣列，稍后我必須var results選擇一個特定的陣列。在這種情況下，我想要的陣列是"results".
var 結果“輸出”：
問題是我想訪問每個陣列的資料，但我不知道該怎么做。
ArrayList list = (ArrayList)results;
StringBuilder builder = new StringBuilder();
for (int i = 0; i < list.Count; i )
{
if (builder.Length > 0)
{
builder.Append(", ");
}
object current = list[i];
builder.Append(current);
}
LblTitle.Text = builder.ToString();
我在其他帖子中看到了這段代碼，我適應了我的代碼，但這只會System.Collections.Generic.Dictionary'2[System.String,System.Object],為每個陣列帶來這個。
string[] arrayresult = builder.ToString();
string[] arrayresult2 = builder.ToString();
對于 object 中的每個陣列，我想要這樣的東西
results。然后像這樣訪問每個陣列資料LblTitle.Text = arrayresult[1]; LblTitle2.Text = arrayresult2[1];
編輯：添加 JSON 示例

我將此 JSON 轉換為 Class，感謝您的提示。這是我現在的課：
public class Result
{
public bool adult { get; set; }
public string backdrop_path { get; set; }
public List<int> genre_ids { get; set; }
public int id { get; set; }
public string original_language { get; set; }
public string original_title { get; set; }
public string overview { get; set; }
public double popularity { get; set; }
public string poster_path { get; set; }
public string release_date { get; set; }
public string title { get; set; }
public bool video { get; set; }
public double vote_average { get; set; }
public int vote_count { get; set; }
}
public class Root
{
public int page { get; set; }
public List<Result> results { get; set; }
public int total_pages { get; set; }
public int total_results { get; set; }
}
uj5u.com熱心網友回復：
我建議您創建一個適當的 C# 類來將您的 JSON 反序列化為。我們看不到 JSON 的樣子，所以我只舉一個簡單的例子。假設這是您的 JSON：
{
"results": [
[
"foo",
"bar"
],
[
"baz",
"qux"
]
],
"someOtherField": "someValue"
}
如果您訪問https://json2csharp.com/，您可以將其轉換為 C# 類，如下所示：
public class Root
{
public List<List<string>> results { get; set; }
public string someOtherField { get; set; }
}
要反序列化和訪問資料，您只需執行以下操作（我使用 System.Text.Json 而不是 JavaScriptSerializer - 請參閱下面的評論）：
var root = JsonSerializer.Deserialize<Root>(apiResponse);
// ...
List<string> listResult = root.results[0];
List<string> listResult2 = root.results[1];
// ...
LblTitle.Text = listResult[1]; // "bar"
LblTitle2.Text = listResult2[1]; // "qux"
請參考JavaScriptSerializer 的定義：
對于 .NET Framework 4.7.2 及更高版本，使用 System.Text.Json 命名空間中的 API 進行序列化和反序列化。對于早期版本的 .NET Framework，請使用 Newtonsoft.Json。
請參閱此處了解如何使用 System.Text.Json。
如果您想改用 Newtonsoft.Json，則應替換JsonSerializer.Deserialize為JsonConvert.DeserializeObject：
var root = JsonConvert.DeserializeObject<Root>(apiResponse);
