C#访问序列化json数组中的值

Question

我有一个简单的序列化json数组

string json = "[{"id":100,"UserId":99},{"id":101,"UserId":98}]";
var data = (List<Model>)Newtonsoft.Json.JsonConvert.DeserializeObject(json , typeof(List<Model>));

我的反序列化模型：

public class Model 
{ 
    public int? id { get; set; }
    public int? UserId { get; set; }
}

从每个索引[？]中检索数据并将其打印到控制台的最佳方式是什么？

Answer 1

您可以执行foreach循环：

foreach(var item in data) {
    Console.WriteLine(item.UserId);
}

Answer 2

 string json = "[{"id":100,"UserId":99},{"id":101,"UserId":98}]";
        var objects = JArray.Parse(json);
        var firstIndexValue = objects[0];
        Console.WriteLine(firstIndexValue);
        foreach (var index in objects)
        {
            Console.WriteLine(index);
        }
for (int index = 0; index < objects.Count; index++)
        {
            Console.WriteLine(objects[index]);
        }
