C#解析多个数组嵌套并且有其他数据类型混合的json字符串

你可以使用Json.NET库来解析这样的JSON字符串。下面是一个示例代码：

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System;

class Program
{
    static void Main(string[] args)
    {
        string json = @"
        {
            ""name"": ""John Smith"",
            ""age"": 30,
            ""isMarried"": true,
            ""hobbies"": [""reading"", ""swimming""],
            ""address"": {
                ""street"": ""123 Main St"",
                ""city"": ""New York"",
                ""state"": ""NY"",
                ""zip"": ""10001""
            },
            ""scores"": [
                [80, 90, 85],
                [70, 75, 80]
            ]
        }";

        JObject obj = JsonConvert.DeserializeObject<JObject>(json);

        string name = obj["name"].ToString();
        int age = (int)obj["age"];
        bool isMarried = (bool)obj["isMarried"];

        JArray hobbies = (JArray)obj["hobbies"];
        foreach (string hobby in hobbies)
        {
            Console.WriteLine(hobby);
        }

        JObject address = (JObject)obj["address"];
        string street = address["street"].ToString();
        string city = address["city"].ToString();
        string state = address["state"].ToString();
        string zip = address["zip"].ToString();

        JArray scores = (JArray)obj["scores"];
        foreach (JArray row in scores)
        {
            foreach (int score in row)
            {
                Console.Write(score + " ");
            }
            Console.WriteLine();
        }
    }
}

在这个示例中，我们使用Json.NET将JSON字符串解析为JObject对象。然后，我们可以使用JObject的索引器来访问对象中的属性和嵌套对象，使用JArray来访问数组和嵌套数组。
