C# Deserialize JSON data

I have a JSON 

{{  "action": "rma",  "devices": "[95001105,30013103,300117]",  "devandreason": [    {      "device": 95001105,      "reason": 100    },    {      "device": 30013103,      "reason": 300    },    {      "device": 300117,      "reason": 200    }  ]}}

for which I'm trying to get the devandreason as an array. I've tried creating classes

public class DevReasonList
    {
        public List<DevReason> devandreason { get; set; }
    }
    public class DevReason
    {
        public Double device { get; set; }
        public Double reason { get; set; }
    }

and the json_serializer:

JavaScriptSerializer json_serializer = new JavaScriptSerializer();
DevReasonList deviceAndReasonList = json_serializer.Deserialize<DevReasonList>(json.devandreason);

but it throws an exception:

json_serializer.Deserialize<DevReasonList>(json.devandreason) 'json_serializer.Deserialize<DevReasonList>(json.devandreason)' threw an exception of type 'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException' dynamic {Microsoft.CSharp.RuntimeBinder.RuntimeBinderException}

But I don't know what I'm doing wrong :(

It is possible to deserialize devandreason and make it an array?

This should be your model according to 

public class Devandreason
{
    public int device { get; set; }
    public int reason { get; set; }
}

public class RootObject
{
    public string action { get; set; }
    public string devices { get; set; }
    public List<Devandreason> devandreason { get; set; }
}

I removed the beginning { and trailing } and it now validates

{  "action": "rma",  "devices": "[95001105,30013103,300117]",  "devandreason": [    {      "device": 95001105,      "reason": 100    },    {      "device": 30013103,      "reason": 300    },    {      "device": 300117,      "reason": 200    }  ]}

Edit: As raised by @Sven in the comments: RootObject would be so much easier to traverse if your devices type was List.

Here is the json that would be required, I just removed the quotes before the value: 

{  "action": "rma",  "devices": [95001105,30013103,300117],  "devandreason": [    {      "device": 95001105,      "reason": 100    },    {      "device": 30013103,      "reason": 300    },    {      "device": 300117,      "reason": 200    }  ]}
