如何将我的C＃数组转换为json？

Question

我试图将json用于我的移动应用程序，然后使用http将文件上传到文件托管站点。 现在，我遇到了问题，因为我试图在列表视图中传递它，并且它不检索任何数据。 我已经在jsontoc＃中对其进行了测试，但是我仍然认为json出了点问题。您能告诉我我做得对吗，还是可以告诉我它出了什么问题？

我的json

[
{
"Mountains": [
  {
    "MtName": "TALAMITAM",
    "Masl":  630,
    "Difficulty": 3,
    "Island":  1
    },
    {
    "MtName": "ALTO PEAK",
    "Masl":  1332,
    "Difficulty": 6,
    "Island": 2
    },
    {
    "MtName": "CANDALAGA",
    "Masl":  1232,
    "Difficulty": 7,
    "Island": 3
    }       
  ]
} 
]

这是我在C＃中的数组

 public static List<Mountain> MountainList = new List<Mountain>()
        {

            new Mountain()
            {
                MtName = "ALTO PEAK",
                Masl = 1332,
                Difficulty = 6,
                Island = 2
            },
            new Mountain()
            {
                MtName = "APO",
                Masl = 2956,
                Difficulty = 7,
                Island = 3                   
            },
            new Mountain()
            {
                MtName = "CANDALAGA",
                Masl = 1232,
                Difficulty = 7,
                Island = 3                   
            },              
        } 

Answer 1

您的JSON具有以下格式：

public class Rootobject
{
    public Class1[] Property1 { get; set; }
}

public class Class1
{
    public Mountain[] Mountains { get; set; }
}

public class Mountain
{
    public string MtName { get; set; }
    public int Masl { get; set; }
    public int Difficulty { get; set; }
    public int Island { get; set; }
}

您有Mountains的数组，因此它与格式不符。 尝试使用上述格式，然后使用Json.NET将类转换为JSON，如下所示：

var ro = new Rootobject();
// more code here to populate the ro properties
var json = JsonConvert.SerializeObject(ro);

Answer 2

Mountain类的列表的JSON是

[
  {
    "MtName": "TALAMITAM",
    "Masl":  630,
    "Difficulty": 3,
    "Island":  1
  },
  {
    "MtName": "ALTO PEAK",
    "Masl":  1332,
    "Difficulty": 6,
    "Island": 2
  },
  {
    "MtName": "CANDALAGA",
    "Masl":  1232,
    "Difficulty": 7,
    "Island": 3
  }       
]

您拥有的JSON是一个类数组，其中包含属性public List<Mountain> MountainList;
