c# - 将 Json 对象数组转换为最合适的 .Net 集合

Question

我有以下 Json 集合，我需要将其表示为 .Net 集合。从本质上讲，它是一个键值对列表，其中的键 (col) 可能有重复项(现阶段字典已出)。

我排序和分组会很好，但不是必需的。能否帮助确定最适合的 .Net 枚举？

[
    {
        "col": "thiscol",
        "val": "thisval"
    },
    {
        "col": "thiscol",
        "val": "thisval2"
    },
    {
        "col": "thiscol2",
        "val": "thisval2"
    },
    {
        "col": "thiscol3",
        "val": "thisval3"
    }
]

Answer 1

使用 Json.Net

dynamic dynObj = JsonConvert.DeserializeObject(yourstring);
foreach (var item in dynObj)
{
    Console.WriteLine(item.col + " " + item.val);
}

或

JArray jArray = (JArray)JsonConvert.DeserializeObject(yourstring);
var newlist = jArray.OrderByDescending(x => x["val"]).ToArray();

或

JArray jArray = (JArray)JsonConvert.DeserializeObject(yourstring);
dynamic dynObj1 = jArray.OrderByDescending(x => x["val"]);
foreach (var item in dynObj1)
{
    Console.WriteLine(item.col + " " + item.val);
}

或内置JavaScriptSerializer & dynamic

dynamic dynObj2 = new JavaScriptSerializer().Deserialize<List<object>>(yourstring);
foreach (var item in dynObj2)
{
    Console.WriteLine(item["col"] + " " + item["val"]);
}
