json反序列化为C#

对我的Web请求的响应如下(不在我的控制范围内):

The response to my web request coming as the following (not under my control):

{
"nasdaq_imbalance": 
{
    "name": "nasdaq_imbalance", 
    "group": "Market Data", 
    "description": null
},
"DXOpen IM": 
{
    "name": "DXOpen IM", 
    "group": "Daily",
    "description": null
}, 
"Float Shares": 
{
    "name": "Float Shares", 
    "group": "Daily", 
    "description": null
}, 

}

不知何故，我需要将其反序列化为包含对象列表的C#对象...基本上，我需要像这样的对象列表:

Somehow, I need to deserialize that into C# object that contains a list of objects... Basically I need a list of objects like that:

public class Dataset    {
    public string name { get; set; } 
    public string group { get; set; } 
    public string description { get; set; } 
}
