无法将JSON数组反序列化为“RootObject”类型

Question

我以下面提到的格式获得json。

[{
    "count":"2",
    "data":[{
        "Name": "Pinky",
        "number": "91XXXX",
        "place": "Mumbai"
    },
    {
        "Name": "Rohan",
        "number": "91XXXX",
        "place": "Pune"
    }]
}]

对于练习，我把它变成了像这样的字符串

string json = "[{
    \"count\":\"2\",
    \"data\":[{
        \"Name\": \"Pinky\",
        \"number\": \"91XXXX\",
        \"place\": \"Mumbai\"
    },
    {
        \"Name\": \"Rohan\",
        \"number\": \"91XXXX\",
        \"place\": \"Pune\"
    }]
}]";

我为此创建了一个类。

public class Datum
{
    public string Name { get; set; }
    public string number { get; set; }
    public string place { get; set; }
}

public class RootObject
{
    public string count { get; set; }
    public List<Datum> data { get; set; }
}

但是当我这样写作时，会收到错误。

RootObject cdr = JsonConvert.DeserializeObject<RootObject>(json);

你的json是一个数组使用

var cdr = JsonConvert.DeserializeObject<List<RootObject>>(json);
