C#按类型解析JSON分组

// JSON数据示例
string jsonData = @"
{
    ""data"": [
        { ""name"": ""John"", ""age"": 30, ""city"": ""New York"" },
        { ""name"": ""Alice"", ""age"": 25, ""city"": ""Los Angeles"" },
        { ""name"": ""Bob"", ""age"": 35, ""city"": ""Chicago"" },
        { ""name"": ""Emily"", ""age"": 28, ""city"": ""San Francisco"" }
    ]
}";

// 解析JSON数据
JObject json = JObject.Parse(jsonData);
JArray data = (JArray)json["data"];

// 按类型分组处理
var groups = data.GroupBy(item => item.Type);

// 输出分组结果
foreach (var group in groups)
{
    Console.WriteLine($"Group: {group.Key}");
    foreach (var item in group)
    {
        Console.WriteLine($"Name: {item["name"]}, Age: {item["age"]}, City: {item["city"]}");
    }
    Console.WriteLine();
}
