来自datatable和IList的嵌套JSON

从数据表中,您有一个 IEnumerable<IDictionary<string, string>> ,因此,您要做的是首先创建查找,然后可以安全地投影结果:

var items = listOfObjects.FromJson<IEnumerable<IDictionary<string, string>>>();

var info = objectInfo.FromJson<IEnumerable<IDictionary<string, string>>>()
    .ToLookup(it => it.Single(k => k.Key == "name").Value, it => it.Where(k => k.Key != "name"));

var restructured = items
    .SelectMany(it => it.Keys)
    .GroupBy(it => it)
    .Select(it => new
    {
        Key = it.Key,
        Value = info[it.Key].SelectMany(fo => fo).ToDictionary(fo => fo.Key, fo => fo.Value)
    })
    .ToDictionary(it => it.Key, it => it.Value);

// extension method with NewtonSoft.JSON.net
public static T FromJson<T>(this string json)
{
    var serializer = new JsonSerializer();
    using (var sr = new StringReader(json))
    using (var jr = new JsonTextReader(sr))
    {
        var result = serializer.Deserialize<T>(jr);
        return result;
    }
}
