将复杂的JSON反序列化为c#对象

我试图将以下JSON反序列化为c#对象。但是，我试图在不为"1"对象创建类的情况下实现这一点。这只是我将要处理的JSON的一小段，一些JSON对象将包含多达40个子对象，这意味着我将不得不复制大量代码。

是否有一种方法可以将这种风格的JSON反序列化为c#对象，而无需为1,2等创建类?

{
"WANConnectionDevice": {
    "1": {
        "WANPPPConnection": {
            "1": {
                "ExternalIPAddress": {
                    "_value": "0.0.0.0",
                    "_timestamp": "2016-08-04T08:51:37.813Z",
                    "_type": "xsd:string",
                    "_writable": false
                    },
                "Password": {
                    "_writable": true,
                    "_timestamp": "2016-08-02T10:40:35.134Z",
                    "_value": "test6",
                    "_type": "xsd:string"
                    },
                "Username": {
                    "_writable": true,
                    "_timestamp": "2016-08-02T10:40:35.134Z",
                    "_value": "test6@test.net",
                    "_type": "xsd:string"
                    },
                "MACAddress": {
                    "_writable": false,
                    "_timestamp": "2016-08-02T16:48:15.188Z",
                    "_value": "",
                    "_type": "xsd:string"
                }
            }
        }
    },
    "2": {
        "WANIPConnection": {
            "1": {
                "ExternalIPAddress": {
                    "_writable": true,
                    "_timestamp": "2016-08-02T16:48:15.188Z",
                    "_value": "",
                    "_type": "xsd:string"
                    },
                "MACAddress": {
                    "_writable": false,
                    "_timestamp": "2016-08-02T16:48:15.188Z",
                    "_value": "",
                    "_type": "xsd:string"
                    }
                }
            }
        }
    }
}

下面是一些类的例子，我可以让它反序列化到不实用或不好的设计，这是我希望避免的。

public class _1
{
    public ExternalIPAddress ExternalIPAddress { get; set; }
    public Password Password { get; set; }
    public Username Username { get; set; }
    public MACAddress MACAddress { get; set; }
}
public class WANPPPConnection
{
    public _1 _1 { get; set; }
}
public class _1
{
    public WANPPPConnection WANPPPConnection { get; set; }
}
public class WANIPConnection
{
    public  _1 { get; set; }
}
public class _2
{
    public WANIPConnection WANIPConnection { get; set; }
}
