所以我是一个完全的 C# 和网络东西的菜鸟，并试图弄清楚一些事情。有一些代码是这样说的：

[WebInvoke(UriTemplate = "People", Method = "GET", ResponseFormat = WebMessageFormat.Json)]
public string GetPeople() {
   Person results = DataAccess.ParsePeople();
   System.WebScrip.Serialization.JavaScriptSerializer oSerializer = oSerializer.MaxJsonLength = int.MaxValue;
   string sJSON = oSerializer.Serialize(results);
   return sJSON;

}

当我输入此方法的 url 时，我的响应如下所示：

"{\"AddressesCollection\":[{\"Street\":\"1234 Temp Dr\",\"Zip\":94011},{\"Street\":\"56789 Nothing Dr\",\"Zip\":2222},\"ErrorMessage\":\"SUCCESS\"}"

我试图在 iPad 端遵循本教程：http ://www.raywenderlich.com/5492/working-with-json-in-ios-5

查看他们用作示例的网站，JSON 输出如下所示：

{"paging":{"page":1,"total":4440,"page_size":20,"pages":222},"loans":[{"id":447290,"name":"Rosa" ,"description":{"languages":["es","en"]},"status":"fundraising","funded_amount":0,"basket_amount":0,"image":{"id": 1134583,"template_id":1},"activity":"Animal Sales","sector":"Agriculture","use":"购买稗鸡和饲料。","location":{"country_code":" PE","country":"Peru","town":"M\u00f3rrope - Lambayeque","geo":{"level":"country","pairs":"-10 -76","type" :"点"}},"partner_id":143,"posted_date":"2012-07-13T19:00:05Z","planned_expiration_date":"2012-08-12T19:00:05Z","loan_amount":400,"借款人计数":1},{"id":447292,"na

在 iPad 上，当我这样做时：

NSDictionary *fields = [NSJSONSerialization JSONObjectWithData:response options:kNilOptions error:&error];

或者

NSArray *fields = [NSJSONSerialization JSONObjectWithData:response options:kNilOptions error:&error];

两者都是空的。是不是正确的 JSON 的 C# 输出？谢谢。

]您的 JSON 字符串在某处缺少关闭。

假设您发布的字符串正是服务器返回的字符串，您可能还需要删除反斜杠以使其成为有效的 JSON。

NSString *responseString = [[[NSString alloc] initWithData:response] stringByReplacingOccurrencesOfString:@"\\" withString:@""];
NSDictionary *fields = [NSJSONSerialization JSONObjectWithData:responseString options:kNilOptions error:&error];
